1 Preface

Under the dual pressure of the WHO Framework Convention on Tobacco Control and domestic monopoly law, the tobacco industry is actively exploring new ways of development, according to the information provided by China Tobacco, the sales volume of industry cigarette 2014 year-on-year growth: annual production of domestic cigarettes 51.7 million cartons, up 2.02% YoY , the cumulative sales of cigarettes 50.9904 million cases, an increase of 2.1% yoy. International tobacco industry is accelerating to globalization, monopoly development, the accession to the WTO to the tobacco enterprises to face more fierce competition, and the WHO Framework Convention on tobacco Control, so that China's tobacco enterprises into the broad merger, remote technology and other high tide, tobacco enterprises demand for information more and more, Integrated cabling system plays an increasingly important role in tobacco enterprises.

In recent years, Rosenberg has actively participated in the comprehensive cabling of many different kinds of tobacco enterprises, and has accumulated a lot of feasible industry experience from various types and different scales of tobacco enterprises ' comprehensive cabling projects. This article will share the experience gained in the actual case for reference in the ongoing or forthcoming project of the Tobacco Enterprise Technical Transformation (offsite or in situ).

2 Cabling and network architecture for the tobacco industry

As an important part of the weak construction project, the integrated cabling system is the most basic physical platform to realize the information communication of tobacco enterprises, and it is the guarantee to realize the application of network communication. Depending on the field of application, the tobacco industry network generally has an intranet (production network), external Network (office network), special Network (Government network) and other points, the different application network between the need for physical or logical isolation. These application networks respectively, the tobacco enterprise's various buildings, such as joint workshop, power Center and raw material storehouse, auxiliary materials storehouse, sewage station, rubbish station and other areas link up (different enterprise name is slightly different, this name is for reference only), finally formed the Tobacco Enterprise Complete network system, 1.

Figure 1 The overall structure of the Tobacco Enterprise network

1. Design and planning of backbone cable in 2.1 Park

Tobacco Enterprise building monomer between the physical distance is relatively far, especially the sewage treatment station, the garbage station access between IDF wait until the aggregation room backbone data cable distance may be far greater than 500 meters, this for the million-gigabit access as the main transmission mode network system, the use of multimode fiber optic cable will not meet the requirements of the entire system, Although the standard specifies that the gigabit multimode OM4 Fiber supports gigabit Ethernet distances of up to 550 meters. Therefore, for tobacco enterprises, especially cigarette factories, the independent construction to the convergence/core room between the access to optical cable is mainly used outdoor single-mode fiber.

In order to ensure the independence and security of different networks, the integrated cabling system of tobacco enterprises needs to support the application of multiple sets of networks. In the traditional network planning design, the network isolation uses the logical isolation way, namely through the switch port different network IP address setting to achieve the network isolation goal. With the continuous development of network technology, the daily production and life of tobacco enterprises is more and more dependent on the network, which puts forward higher requirements for the safety and reliability of the network. In the current tobacco industry in the design of integrated cabling, many tobacco enterprises in the new project has adopted a more reliable dual data backbone, physical isolation and other ways.

1. 2.2 Design and planning of traditional weak motor room

It is well known that tobacco enterprise building monomer number, large building area (basically more than 100,000 square meters), network systems used more than three-storey star-type architecture, weak motor room is divided into the core layer CD (Enterprise Core Room), the aggregation layer BD (Building equipment MDF) and Access layer FD (floor wiring between IDF) and other categories, In order to ensure the safety and reliability of the network, the integrated cabling system of the tobacco enterprise is equipped with two data backbone cables, such as the core layer CD and the aggregation layer BD, the aggregation layer BD and the Access layer FD, the overall network cabling Planning 2 is shown.

1. 2.3 Cabling planning for the tobacco industry

2. 2.3.1 Core layer CD, Convergence layer BD weak device planning

The core CD room needs to be terminated from the aggregation room, operator access network and tobacco system in the introduction of various types of optical fiber, optical fiber core number, in the CD room should be based on the specific number of optical fiber and cabinet installation space, select suitable for the project needs of the fiber-optic fusion wiring rack products, such as 1hu-24 Core, 1hu-48 core, 5hu-288 core and so on.

Tobacco enterprises in the number of end-fiber aggregation room, access to the engine room upstream and a large number of optical fiber and upstream to the core room of optical fiber are to be terminated, management, the general aggregation room at the same time assume the function of the access room, in a limited cabinet space, the need to install a large number of optical fiber and copper cable distribution rack. This area of optical fiber wiring frame is recommended to use 1hu-48 Core, 5hu-288 core, such as higher density fiber distribution rack products, such as 5hu-288 core fused fiber wiring frame, its fusion fiber modular structure, self-equipped with cable, more than conventional 1hu-24 core fiber cable rack can save 80% of cabinet space.

2.3.2 Access Layer FD weak motor room (IDF) planning

Compared to the core layer and the aggregation layer, the access layer weak motor room of the IDF backbone fiber is generally less (except for optical fiber to the desktop project), for the termination and management of fiber optic fiber distribution rack selection of conventional 1hu-24 core fused fiber structure can be. For a small number of access to the IDF, such as cabinet space allows to avoid the use of higher densities of different specifications of the optical fiber distribution rack.

The access room carries the entire project project level information Point management work, in from the point aspect each access room needs to manage dozens of to hundreds of information points, in the area area covers to the entire even several production work floor. For the IT maintenance personnel of tobacco enterprises, it is very complicated and difficult to manage the whole enterprise's large network system, the system reliability and management convenience of the whole cabling are very important to improve and improve the enterprise's it efficiency.

1. 2.3.3 Access Layer FD weak motor Room (IDF) scheme optimization

Access room in the selection of integrated wiring rack products, in addition to consider the need for maintenance management, but also to consider the wiring frame module terminal dust-proof function. Room decoration and cleaning process of dust, water droplets, etc. will be the wiring frame module gold-plated pin needle damage, this damage will directly affect the service life of the module, and this damage is generally relatively covert, in the project completion test, the link performance is good, After 3-5 years of product use after a sharp decline in performance (PIN gold plating layer after wear and tear caused by oxidation), to this time the project's warranty period has been finished, thereby causing a great loss to the user.

In order to solve this potential risk, when choosing the horizontal copper cable rack, we should choose the products with dustproof function as far as possible. If you choose a cable rack port with a push-pull dust door copper cable rack, when the wiring rack port has not been connected jumper (the room decoration when the wiring rack port is not connected to the jumper), the wiring rack on the dust door from the reset to the module pin completely covered, to prevent dust, water droplets and other entry. In order to prevent the label and other labels from falling and missing, the label system of the wiring frame should choose a way of long-term retention, such as transparent arc flip tag protection cover structure, 3 Rosenberg dust-proof cable rack.

The access room of tobacco enterprises is distributed in all kinds of building monomers, although most of the weak motor room has the space of standard floor room, the other part of the building monomer to save limited building space, choose to use small wall-mounted cabinet, this kind of cabinet capacity is small, cabinet can only be front-end maintenance. For this type of area in the distribution rack products, can choose to use the light copper mixing, front-end maintenance structure of products, such as the Rosenberg company taurusii Light copper mixed wiring rack.

Actual operation of each project in the access room will have their own specific special needs, and even the same project different areas of the requirements are not the same, in the network planning should try to choose suitable for the project needs of the product, from the design stage began to control the incidence of network failures, avoid the potential risks of integrated cabling, improve network reliability, Stability.

1. Cabling Management in 2.3.4 tobacco industry

The distribution of information points in each building monomer in tobacco enterprises is very scattered, the daily management and maintenance is very difficult, in order to improve the system reliability and management convenience, the access room recommended the use of self-management function of intelligent cabling System (electronic wiring rack). The system is used to track the daily jumper maintenance by electronic work order, to avoid the loss or error of work order record in conventional mode. The jumper plug is booted by the LED display light of the corresponding port of the electronic wiring frame to avoid the network risk caused by the port jumping error; For unauthorized jumper operation, the alarm prompt is passed in real time. To detect network failure and nausea damage; the physical location of all information points of the enterprise is quickly located through the plane drawing, which helps IT staff to quickly find the fault location and restore the network application as soon as possible. Graphical computer room management helps enterprise IT staff to understand the cabinet and equipment resources, etc. It can save a lot of time for on-site checking, and the network management mode greatly improves the efficiency of IT management, and enterprise IT staff can know the network running status in time by remote login. The smart cabling system can implement some of the features shown in 5:

Figure 5 What the smart cabling system can achieve

Intelligent Cabling System to achieve the management of integrated cabling, the system uses a completely independent of the Ethernet Management Network, has its own independent intelligent host, Management unit and scanning module, the use of dual wiring frame architecture of the link technology, the information points and switch ports are mapped to different electronic wiring rack ports, Through the smart jumper according to the requirements of the map of the information point port and switch/voice distribution rack port of the wiring rack port for proper connection, and finally through intelligent management software to the integrated cabling system intelligent management.

1. 2.3.5 Tobacco Enterprise Information Point Planning scheme

The production automation degree of the new tobacco enterprise is very high, whether it is silk, reel or finished goods warehousing has realized the assembly line automation production mode, the safety and reliability of production network are of vital importance to the production efficiency and product control of tobacco enterprises. Work area information Point Copper module should choose the RJ45 interface general-purpose products, in order to reduce the difficulty of late maintenance, we recommend the use of no installation tools without the tool-free module (especially do not use the manufacturer to provide special installation tools of the so-called tool-free module), for the fiber module is recommended to use the RJ45 module installation compatible type, Not only is the installation more reliable, it can also be integrated with the wall or floor mounting panel of the copper module.

1. Cabling scheme for Special area of 2.3.6 tobacco

For some special occasions such as VIP reception room, wall decoration is generally more characteristic, the use of ordinary wall panels may not be in harmony with the style of these areas. In such areas it is recommended to select special products, such as the Central Rosenberg pop-up panel, which can be customized according to the decoration style. When the information point is not used, the module is hidden under the information Panel, you need to use a simple press the button under the Panel, routine maintenance is done through the front panel, no need to remove the panel frame, will not affect the decoration wall and damage.

650) this.width=650; "style=" width:648px;height:211px; "title=" Untitled -3.jpg "src=" http://s3.51cto.com/wyfs02/M00/72/ 2e/wkiom1xeep6gp65vaaqrxsrfr8o337.jpg "width=" "height=" 849 "alt=" wkiom1xeep6gp65vaaqrxsrfr8o337.jpg "/>

Figure 6 Pop-up wall panel

Some projects in the planning and design needs are not completely clear, such as a tobacco enterprise new project is the merger of 2 different tobacco factories, many offices in the number of office staff, desk location, etc. can not be determined, the choice of conventional wall or ground installation information points can not solve the problem. For similar problems, can be solved by the way of two wiring: the project design of all the information points in this area are installed in the same wiring box, follow-up according to the change of office personnel, through the way of long jumpers to connect to the office personnel Terminal equipment. The wiring box can be pre-installed in the wall or installed in ceiling ceilings.

Some projects, such as the provincial and municipal tobacco Monopoly Bureau, due to a wide range of business, the growth of data demand is very rapid, network planning should be at least to meet the needs of the next 10 years. Due to the inability to predict the development of terminal equipment ports within 10 years, in order to meet the current RJ45 copper interface-based network needs, in some important areas should also be reserved for future equipment fiber optic interface needs. In order to meet the future change of equipment port, at the same time make the project investment more economical, optical fiber information points recommended the use of centralized cabling, from the weaknesses into the computer room IDF cloth cable to the office area of the central cabling area such as wall-mounted optical fiber wiring frame, the wiring frame can be installed in the daily office of the corner or ceiling ceiling area With the increase of the fiber-optic port device, the corresponding fiber jumper is added.

Whether for wall or ground mounting, single or double-hole panel/interpolation should be used as much as possible, since in each of the bottom boxes there is a need to coiled a cable for subsequent maintenance in addition to the information module. If the module installed in the same bottom box reaches 3 and above, there is almost no space to coil the reserved cable, especially for six types of shielding and the above level of cable products, each bottom box to accommodate 2 shielding module space is already relatively tight, 3-well and 4-hole panel panel almost no matching with the installation of the bottom box.

For the use of welding fiber information points, horizontal cable should be selected in favor of welding products such as tight-type indoor cable, such as the use of on-site crimp connectors, the tight sleeve indoor cable and leather cable can be selected.

1. 2.4 Tobacco Data Center Network Architecture Planning

2. 2.4.1 Tobacco Enterprise Data Center room cabling characteristics

Compared with the data centers of hundreds of thousands of cabinets, such as the Internet and the financial industry, the data centers of tobacco enterprises are generally smaller in size and the number of cabinets is within 100. This kind of enterprise's self-occupied data center construction initial equipment Port utilization is relatively low, network system for the comprehensive cabling in the scalability, flexibility and management requirements higher. Data Center network architecture design whether from the economic or practical aspects of consideration, the use of EOR approach is more suitable, according to the specific needs of different projects, you can choose the switch direct or cross-mode wiring.

Tobacco Enterprise Data Center network architecture design, according to the number of cabinets, management needs, such as the choice of whether to adopt the Mda-hda-eda three-layer network architecture. When the number of cabinets is less than 20, such as the location of the cabinet is reasonable, the use of Mda-eda two-layer network architecture can also be very good to meet the requirements.

Tobacco Enterprise Data Center each region according to function can be divided into: main wiring area, switch zone, server area and storage area. The whole network is mainly composed of LAN network based on TPC/IP and FC-based storage network SAN, because the two kinds of networks follow the different transport protocols, the integrated cabling planning design should be designed separately for them.

For data transmission requirements higher SAN Network, integrated cabling planning regardless of the network architecture, are recommended directly through the pre-fabricated optical cable connected to the main wiring area, that is, the Mda-eda two-layer network architecture, minicomputer, storage and other areas using centralized integrated cabling method.

The main wiring area brings together the backbone copper cables and optical cables from each of the header cabinets (or server cabinets), planning and design should not only meet the current wiring requirements, but also for future expansion to reserve enough space for wiring.

In particular, when the switch area is distributed for the core switch, it is recommended to use cross wiring to plan the layout of the integrated cabling, in the core switch cabinets in the assembly line rack, through the horizontal cable connected to the main wiring area, in the main wiring area through the jumper and the header of the line over the trunk/horizontal link to jump, all the backbone/ The connection of the horizontal link to the core switch port is done only in the main wiring area.

Server cabinets, including core network equipment cabinets, each cabinet should be installed according to the number of device ports enough light, copper wiring rack, the number of ports according to each server 2 optical ports, 2 copper ports (one Master one) and 1 for the KVM System copper port for the calculation, but also for future system expansion to reserve some ports.

According to the model provided above, the typical Tobacco Enterprise data Center network topology 7 shows that the main wiring area adopts the cross wiring method.

Figure 7 Data Center room topology diagram

In the current environment of Chinese tobacco enterprises to carry out merger and reorganization extensively, the scale of the tobacco enterprises after reorganization is increasing, the production automation degree is increasing, and the adoption of the virtualization technology also brings the rapid growth of the data volume, so the data volume of the Enterprise Data center will continue to increase, in its current in the million backbone, Gigabit access based on the network, we should also consider how integrated cabling to meet the needs of the next few years of network transmission, data center in the next few years will gradually realize the gigabit access, 40g/100g backbone of the network transmission mode.

Tobacco Enterprise Data Center in the selection of media can refer to the following scenarios: from the head cabinet to the server cabinet horizontal link between the deployment to million access, copper cable Select Super Six series, cable is more cost-effective OM3-based. The integrated cabling plan is as follows: The MPO/MTP-MPO/MTP Multi-core pre-connected optical cable is deployed between the main distribution area and the horizontal distribution area header cabinet, respectively, to the main distribution area wiring cabinet and the fiber optic wiring rack module in the header cabinet, Connecting the core switch to the access switch via the configured Gigabit fiber module and the Gigabit jumper, as the physical link supporting the current backbone Gigabit Network application, when the network needs to be upgraded from 10G to 40g/100g, simply replace the cable rack 10G module and the device jumper on both ends of the pre-connected optical cable to 40g/ 100G modules and jumpers, the deployment of gigabit copper cables between the access switch and the server.

1. 2.4.2 Main wiring Area integrated cabling

The main wiring area MDA is the core of the whole data center, and also the central distribution point of the data center structured cabling system, the backbone optical cable of the whole data room will be connected to the MDA for cross wiring, so the region needs to manage the number of optical fibers and high density. Fiber optic wiring Frame recommended the use of 4u-288 core/384 cores and other high-density products, such as the Rosenberg Taurusii, Vela High-density fiber distribution rack, 4U space can be achieved 288-core ~384 core pre-connected cable installation, with a cable and light two sets of labeling system, From the installation density of more than the traditional fiber distribution rack to save more than 60% of the installation space, modular installation mode to make the management of optical fiber more convenient and flexible, with the Rosenberg low-loss, anti-bending fast plug fiber jumper, achieve a high density and maintenance of the perfect combination of convenience, 8 shows.

1. 2.4.3 Server, network equipment cabinet integrated cabling

In the tobacco enterprise data servers, network equipment cabinets and the use of rack storage equipment and other areas, in order to make management more efficient and flexible, integrated cabling more EOR way, that is, on each cabinet installed a sufficient number of fiber optic wiring rack and copper cable distribution rack. In order to meet the needs of the virtualized network system for data volume, we should choose the million gigabit transmission medium such as CAT6A Super Six million Gigabit copper cable and the cost-effective OM3 million Gigabit optical fiber cable.

For different EDA cabinets integrated cabling Planning is also different, server cabinets because the installed server network port may be copper cable connection, may also be an optical cable connection, according to the above mentioned in accordance with each server cabinet reserved 2 optical ports, 2 copper ports and 1 KVM Copper port configuration, considering the need for partial redundancy, Each server cabinet configuration 24-core fiber, 24 copper port should be able to meet most of the tobacco Enterprise Server cabinet cabling needs, network equipment cabinets installed in most of the network equipment is a light-mouth mode, considering that there will also be a part of the demand for copper, so in the planning and design according to the 48-core cable per cabinet, 24 copper cable calculation more appropriate , and storage cabinets and small machines and other areas of optical fiber number is relatively high, the device interface basic not copper, copper cable is only used for KVM cabling, so the region in accordance with each cabinet laying 48~72 core fiber, 12 copper cable Basic can meet the demand.

The above-mentioned regional cabinets recommended transmission media and the specific number of tobacco enterprise data Center planning and design as a reference, the actual project case of integrated cabling should be based on actual needs and predictable expansion needs, and then add about 50% redundant link. Considering the characteristics of the Tobacco enterprise Data Center, whether it is the traditional field cabinet assembly method or the present more popular micro-module room, the EOR network architecture should be given priority.

3 concluding remarks

As a industry with its own characteristics, the construction of its integrated cabling system has its own unique characteristics: The main link is due to the large campus, the single building is more, so the choice can support longer transmission distance of the mono-mode fiber optic cable; the rest of the office area includes the joint workshop, The distribution of information points, such as power centers, is more dispersed, and because production needs can not fully provide the space for the standard weak motor cabinets, more flexible small wall-mounted enclosures may be considered as weak motor cabinets in these areas, and scattered information points provide a lot of trouble for daily management and maintenance. Therefore, the use of electronic wiring rack in the integrated cabling system is worthy of reference in the tobacco industry; In addition, the construction and installation of special Area information points is one of the problems that can not be neglected.

For the tobacco industry Data Center room, in addition to the need to manage the internal production, management and daily office data, but also need to maintain data interoperability with the superior units in real-time, so the construction of data center can not only meet the current data transmission requirements, but also to meet the future of the minimum 10 network upgrade required transmission link requirements, Therefore, the data room should consider the access layer to meet the gigabit transmission, backbone link should be able to support smooth upgrade to 40g/100g Ethernet.

With the stricter standards of tobacco control in the country, the increasing demand for informatization of the newly-built enterprises is becoming more and more important in the development of the integrated cabling system in tobacco enterprises. China's tobacco industry in a certain period of time will still be in a wide range of mergers and technological upgrading of the climax period, hope that the introduction of this article on the tobacco industry Integrated cabling Construction has a certain reference significance.
