Multi-Service Router

The application of multi-service routers is very extensive. So I studied the application of Multi-Service Router instances. I would like to share it with you here and hope it will be useful to you. Multi-Service routers have a series of functions such as data processing, voice, security, and optimization. What functions do users most care about? Almost everyone puts "data exchange capabilities" at their first choice. The user has placed "WAN performance optimization" at an equally important position as "voice and security", followed by "good scalability" and "good manageability ". Data exchange capabilities, voice and security functions are well understood by users. Why is WAN performance optimization so concerned? In fact, this once again reflects the application-oriented principle.

As enterprises increasingly distribute data center-based applications to remote organizations, the experience of IT staff and users on application performance is reduced due to Wan latency and other issues. To this end, WAN performance optimization has become a huge emerging market, and integration is undoubtedly a good solution in Multi-Service routers. In addition, all users put QoS first in terms of support for PoE, QoS, MPLS and IPv6. Indeed, the core of multiple businesses is to differentiate the types of businesses, and then provide corresponding policies based on different businesses to allocate different service quality. As said Wu Jianxin, Cisco ISR product manager, "QoS is critical and quality of service must be allocated to each application ." Currently, there are many applications in the network. Only by implementing different policies for different types of applications can key business applications and P2P applications be mutually independent. While providing different bandwidth control for various businesses, it ensures business efficiency and reduces bandwidth costs.

Currently, multiple service routers have excellent QoS capabilities. For example, the Samsung Ubigate iBG integration platform not only has strong routing functions, enterprise-level switching capabilities, but also provides VoIP and integration security, in addition, QoS also has a good performance. The Ubigate iBG series products use a wide range of QoS features to truly integrate enterprise voice and data services and support analog/digital and IP phone calls. In addition, by securely expanding the IP phone service on the Wide Area Network, the Ubigate iBG series can increase the user's business communication efficiency to a new level.

Effectively reduce total investment

In today's selection from the perspective of total TCO), it is difficult for any product to achieve the desired success if it cannot effectively reduce TCO. In the answer, "what do you think is the biggest benefit of Multi-Service routers ?" Among the problems, 55% of users chose "one machine and multiple machines", while only 25% chose "Saving total network investment ". It seems that many users ignore this. The reporter obtained the following "accounting" from a vendor, which is worth studying. To save the cost of leased lines, a company plans to use IPSec VPN for virtual leased line interconnection and integrate all 30 offices in China into one network. In addition, VoIP should be used to achieve unified communication nationwide. Because this network is carried by the Internet, in order to achieve the desired transmission effect, you must implement wide area acceleration to improve the Web and voice service capabilities.

In the traditional way, you can plan the network as follows: each office is configured with a WAN router and the following is connected to a central Ethernet switch. Because of the large data volume and the demand for absolute confidentiality, therefore, the VPN gateway must have a strong encryption performance. The Voice Gateway is configured with an E1 Programmable switch, one E1 is connected to the carrier, and two 10-Gigabit ports are connected to the IP network. Dedicated WAN optimization devices are added. In a rough calculation, each office only needs more than 0.25 million yuan of equipment. In addition to the integration cost and installation cost, the initial investment of each office is about yuan. In addition, maintenance is required in the medium term. The service cost of each device, coupled with the cost of replacement of vulnerable devices such as fans, power supplies, cables, and optical modules, is no less than five thousand RMB per year. In addition, the power of these devices is not small, and the power of each power is calculated as 0.5 yuan. The cost of electricity is only several thousand yuan a year. After all calculations, the O & M cost for each office should be at least 60 thousand yuan in five years. There is also a resizing problem. In the next five years, an office will have to invest more than 0.3 million yuan, and 30 offices will have to invest 9 million yuan.

What if I use a multi-service router? If you configure a Multi-Service Router for each office, the situation is quite different. A certain brand of Multi-Service routers) can achieve a route throughput of 600 Kpps, supports high-density switching modules, and supports up to one hundred Ethernet port access; it takes tens of thousands of yuan to configure an IPSec Encryption Engine with a Mbps encryption performance. This engine can replace the high-performance VPN gateway, and then configure an E1 speech module with two ports, one E1 is connected to the PBX, and one E1 is connected to the PSTN, which requires tens of thousands of yuan. WAN optimization can be achieved by configuring the router's open business platform, and then you only need to purchase the corresponding software. In this case, it takes only 10 million CNY to purchase the device. Each office has only one device, and the Integration fee and installation fee are also reduced accordingly. The initial investment in each office cannot exceed 0.12 million RMB. Each Multi-Service Router costs several thousand yuan of maintenance every year, and only one device is managed, and the power consumption is greatly reduced.

In this way, if a Multi-Service Router is used, one office will only spend 0.17 million yuan in five years, and the total investment of 30 offices in five years will not exceed more than 5 million yuan. Compared with the traditional method that requires 9 million yuan, does it save nearly 4 million yuan?

Case Analysis

What are the application effects of Multi-Service routers that are widely favored? Let's analyze it through an instance. Supporting multiple services and reducing costs is the biggest role of Multi-Service routers. McHenry savings bank is located in McHenry County, Illinois, with five branches offering comprehensive financial services. Banks always invest a lot of money in technology to enhance customer service, promote business growth, and maintain a competitive advantage. Bryan Nash, senior vice president of the Information Technology Department of McHenry Savings Bank, said: "Cisco ISR 2800 and 3800 have helped us improve network reliability, performance, and service capabilities, so that we can be on par with large-scale multinational banks. ISR's voice function greatly simplifies the network running process of McHenry and prolongs the normal running time of the network. Implementing Cisco solutions has helped us reduce our operating costs by $46 thousand ."

Let's take a look at domestic cases. In the three-level network transformation project implemented by the Agricultural Bank of China Hebei Branch (ABC), all county-level branches in the province use cisco ISR 250. Through Cisco's ISR 2800, ABC of Hebei transformed its original independent production, office, intermediate business, and customer service networks into a unified physical network, while logically maintaining the independence of several networks, this ensures data security, saves Wan lines, and facilitates management. Cisco ISR integrates multiple features such as voice and security, which are easy to manage and supports advanced applications for future network expansion. It is very suitable for the development of ABC's business. A good QoS mechanism is used to classify multiple businesses and provide bandwidth assurance for latency-sensitive businesses. Hardware acceleration for voice, IPS, and other functions ensures high performance of the ISR router and provides support for many businesses of ABC in Hebei.

In the banking industry, production networks generally only run business systems, which are relatively secure. office system applications are often vulnerable to viruses, Trojans, and other security threats. The separation of production network and office network helps to ensure the safety of production network. The mpls vpn technology is used to solve the problem of ABC in Hebei. According to Neil Rickard, vice president of R & D at Gartner, "for a long time, companies have been hoping to encrypt traffic transmitted through excessive protocol tags for VPNMPLS/VPN exchange to meet system compliance requirements. The existing tunnel-based encryption technology makes it difficult to meet this requirement without affecting the service quality and capability ." Cisco get vpn provides scalable, extremely secure, and arbitrary connection while using inherent routing capabilities. Customers can use cisco get vpn in a variety of Wan environments, including Multi-Protocol Label Switching MPLS), without Point-to-Point Tunneling, thus reducing the latency of large networks, it also improves the performance of speech and video applications.

Focus on the System

Data, voice, security, optimization ...... There are indeed many things that multi-service routers need to solve. However, as a unified integrated platform, we cannot separate various functions, but should focus more on the system. In other words, a Multi-Service Router cannot be viewed as a simple building block, but as a whole.

The system is easy to implement. Because, first of all, this requires the effective and reasonable integration of hardware, software, and applications. This is beyond the "performance" and "function", and whether the fish and the bear's paw have both advantages. Second, this requires the overall optimization of the system and efficient management at the system level. In addition, this also requires the ability to meet new user needs. In other words, we need to constantly add new "things" to multi-service routers. However, there is good news that Cisco ISR can provide 3G modules and satellite modules, which is a good choice for users in some remote areas. In this case, the Multi-Service Router has a very broad path, but it is just on the road.
