Where are the future market of Ethernet switch ?

Ethernet switch Huawei Switch is people are developing the next generation of switching technology, the current switching technology is all based on the electrical signal,with the progress of technology, half Double Union gradually withdraw from the stage of history, take out here and share with you.

At present, more and more manufacturers to enter the Ethernet market, the new brand, new products continue to emerge, seems to have been the homogenization of the competition trend. However, it is worth mentioning that,Ethernet switches in the market to expand the number at the same time, quality requirements are also rising.

Just meet the simple connection and data transmission function, apparently unable to adapt to future needs. Cisco believes that, in the actual market, the development of Ethernet switch products are along the three direction of development speed, intelligent application and coverage, whether for modulechassis Ethernet switch in the high-end, or for a fixed port switch in the low-end,can adapt to this development trend.

Speed is the main sign of network performance. From fast / Gigabit to Gigabit /Gigabit Ethernet, is an important milepost 30 years of development history of.Gigabit network era will bring new experience is completely unthinkable to people.At present, people demand on bandwidth is rapidly increasing, as the rapid development of the network storage required massive data transmissionchannel;

Lots of 100m bandwidth aggregation of metropolitan area network; broadband applications continue to enrich the bandwidth required to support the large financial institutions; data collection; extended enterprise core business, ERP,CRM and other complex. Today the mainstream Gigabit backbone structure, 100Mbit access, will gradually to the structure transition 10 Gigabit backbone, Gigabitaccess. On behalf of Cisco to launch a new generation of Ethernet switch products Catalyst6500 and 3750 series is a new generation of 10G / Gigabitswitch.

On the basis of many years experience in network construction and the development trend of speculation, Cisco believes that the current Ethernet switch technology applied in the following exchange implementation and securityof QoS, support for voice will become a development direction. Intelligent voice service Ethernet switches can be integrated data and voice transmission,customers only need to maintain a unified network system, which greatly saves the cost of network management.

Ethernet voice service can not only ensure the excellent call quality, but also hasrich value-added application development. In addition, as a part of the switch to start directly connected to the network, more and more switches possess somerouting function. Considering the next generation Internet Protocol IPv6 large-scale application in the future, a new generation of Cisco switches also adopted the hardware support for IPv6.

Ethernet is expanding its coverage, positive wireless and long distance direction.Cisco Wireless Network provides a perfect solution for the user, the wireless network in the application of group users, office and convenient customer. Based on the wired network system, Cisco has set up a wireless network, the wired and wireless complement each other, so that the two form a fusion and unity of the good.

In addition, Si chief range Ethernet scheme, also the expansion of Ethernet in the distance. This technology is a telephone line Ethernet, transmission at the physical layer is VDSL signal, transmitted in the second layer Ethernet signal. It can extend the transmission distance, from the original 100 meters extended toup to 5 kilometers, is especially suitable for the metro area, and the speed is constant, any cable can support, greatly facilitate the application.

System development

From the system point of view, Ethernet switches can be divided into fixed port switch and Ethernet switch module chassis. Among them, switch port fixed port of the switch and switch is basically fixed together; and each module chassis switch the switch port is inserted plate.

Modular, according to need or. Under normal circumstances, in the low-endapplication of the former is mainly used for the network, which is mainly used forhigh-end applications. These two systems products, will develop to speed,intelligent application and coverage of the three directions.

Extended the capacity utilization of stacking manner can be fixed port of the Ethernet switch, so that improve the speed of the whole network, but the stackshould not just physically together. A new generation of stackable switch CiscoCatalyst3750 introduced an innovative technology of intelligent stack(StackWiseT).

Innovative stacked architecture which provides the stacked interconnection of a 32Gbps, can stack up to 9 switches, and make them realize from physical stack to logical data comprehensive unified management and planning. The integrationand optimization of the whole equipment, can provide customers with more confidence the deployment of voice, video and data application.

For many the most important trend of chassis module of core network ofEthernet switch is ten thousand, the product key components within the chassisperformance is more and more powerful. Due to the adoption of more flexible modular structure, it can provide the basic functional modules connected withvarious.

Cisco is a new generation of Catalyst6500 switch, is ten thousand excellentswitching performance of the most striking. A switching matrix it is equipped with a switch engine powerful and built-in hardware acceleration, and to realize thehigh performance embedded network management functions, such as MPLS,IPv6 intelligent service hardware support, through distributed forwardingtechnology to achieve the performance up to 400Mpps.

Cisco is the original Catalyst6500 based on the development of many newfunction module, these modules are compatible with all existing Catalyst6500interface and service module, provides an efficient and economic way totransplant to Gigabit Ethernet for users. Technical progress of the wheel still rolling forward, broke three speed, intelligent application and coverage, Quidway S7700 the Ethernet switch has leapt to a new level.
