New features of the switch

Environmental characteristics:

Enterprise Application surge drives Ethernet switch development

Ethernet has the advantages of simple connection and better performance price, and has more and more development space. Therefore, the current use of Ethernet technology to achieve broadband communications has become the focus of industry attention.

The superiority of the network can only be vividly manifested in the practical application, and the specific application demand changes with the market environment. Initially, the enterprise's demand for the network is office automation, which is manifested in file printing, file transfer, file storage, Web browsing, and simple graphics and image fast transfer. In the enterprise implementation of office automation, CRM and ERP implementation needs to be put on the agenda, the media has been a lot of related reports in this regard. After the advent of broadband networks, people's demand for the network has become higher, such as video on demand and MP3 multimedia applications. In the continuous development of the environment, Cisco and other network companies to integrate market demand in the network, according to customer demand to develop new products, new equipment, improve people's work, study and quality of life.

Technical Features:

Switch heavy on "smart swap"

The meaning of intelligent Exchange is to provide an architecture to meet the needs of applications and solve existing problems. To put it simply, is to bring to the user what is actually needed. The concept of intelligence is relatively not intelligent, then, what does network intelligence mean?

Let's use the example of broadband to illustrate the meaning of intelligence.

For a 10 Gigabit Ethernet individual user, this 10 Gigabit Ethernet can be called the real broadband? No. This is because, as the user's increase, the network's demand for bandwidth is more and more high, but the network's own attributes make backbone network bandwidth is difficult to change.

Furthermore, if the bandwidth increases, although the connection between the user and backbone network expands, but if the Exchange processing device located in the Network Center can not store the data well, then the network can not be well applied.

In addition, users tend to use gigabit technology at the edge of the network to transmit data to the backbone network, then, in the implementation of data forwarding, from 10 trillion to 1000 trillion line transmission is no problem, but if you want to 1000 trillion backbone data through the central forwarding processing equipment to 10 trillion users, there are some problems, No reasonable technology is impossible to deal with.

To sum up, the switch requires intelligent exchange, which Cisco has vigorously advocated.

function characteristic:

The importance of network management is increasingly highlighted

The biggest difference between a PC and a network device is that a single PC has value, but network devices are only useful when connected to each other.

In the interconnection of network devices, there are problems of how to connect and how to optimize.

From the date of the birth of the network, the concept of NMS has appeared. Network management system, refers to SNMP Simple Network Management Protocol, that is, in the hardware or network management system software plus hardware to reflect the way. For example, a device vendor will hardware a set of management software into a switch and router, or put it on the backbone of other network systems, the device in this network can be called network management devices.

Network management is not only the administration of networked devices, but also the monitoring and management of network data flow. Because the switch is the network data flow establishment management, needs the massive computational resources, therefore, in order to save the equipment cost the goal, some company has introduced omits the network management function part the switch. However, all Cisco products are network management equipment.

The concept of network management can be divided into two aspects, first refers to the network device itself to the data flow management, it is through the exchange of equipment and routing equipment to achieve; Next is the network device itself can be managed, the user can through the network platform to the IP address, network equipment and so on management.

The beginning of the network, the structure is relatively simple, the application is not too complex, at that time the main reference standard of network management is: whether the equipment can be managed, the switch can be NMS. With the improvement of the network requirements, the network structure becomes more and more complex, and the network management function can be better regulated and integrated with the business, so that the IP business invested by the enterprise could be carried out better. This also prompts switch technology to extend from the original second tier to the third and fourth tiers, from the original two priority queues to the current four priority queues, from simple permutations to complex, recyclable, and optimized systems.

Market Features:

Product competition is fierce

With the development of domestic information technology, the switch market is also expanding. However, because the domestic network environment differs from the foreign network environment, the technology management, the development idea also has the very big difference, therefore, the domestic manufacturer and the international manufacturer still at the different development stage.

China has officially joined the WTO, the domestic exchange market competition will be more intense, in this field of the various manufacturers have both cooperation and competition, in many technologies, products and services, domestic development level with the distance has been pulled very close. After China's entry into WTO, it is a good idea for Chinese and foreign manufacturers to win in this market with more in-depth cooperation in higher level and wider areas.

Objectively speaking, the emergence of new competitors in the market, this is a good thing for any manufacturer. There is competition, manufacturers will be more efforts to provide customers with better services, users have a greater choice of space.
