Ethernet switch requirements in the cloud computing era

How much do you know about cloud computing? Today's small series will give you a brief introduction, welcome to study together. Because of the continuous development of ASIC technology and network processor, as well as the network slowly occupied by IP technology, Ethernet technology has already crossed the LAN era, and more and more applications have been developed in metropolitan area Network and WAN. All routers have a rich network interface, at present, it can be implemented on the switch, while the rich routing protocol in the router can also get a lot of applications in the switch, and the router's large capacity routing table can also be realized in the switch, which lays a solid foundation for the multi service carrier of the switch.

And as more and more businesses migrate to the cloud, different services must have different quality of service assurance, which requires the switch can provide a guarantee of differentiated quality of service, especially the voice and video and so on the network delay and Jitter has a high demand for real-time business class, requiring the switch must be able to support QoS, Flow engineering and other technologies, but also in the flow identification, bandwidth control, traffic engineering and other aspects need to have the requirements of the telecommunications level.

ZTE Exchange has 10GE, GE, FE, POS, Pon and other rich interface modules, and fully support IPV4, IPV6, MPLS, NAT, multicast and other business functions, support hierarchical QoS, to achieve accurate business control, Ensure that the desired quality of service is met by a variety of services hosted on the network. In early 2009, Australia Telecom (Amcom) selected the ZXR108900 series switch to build its national backbone network, carrying its complex operations through ZXR108900 's rich MPLS features.

High Security

Cloud computing brings us great convenience at the same time, the shortcomings are also obvious, the enterprise data and applications are located in the cloud, once the security is insufficient, the consequences are very serious, sensitive data theft will directly on the Enterprise intellectual property rights, corporate reputation and other serious impact. Cloud Security is a systematic project, involving many aspects. In the network security aspect, not only needs the traditional firewall, the IPs and so on security equipment, as the network core Ethernet switch also must have the prevention attack, the anti-virus and so on security function. Advanced network equipment, must have an enhanced security design, so that every network element in the network has a security mission to meet the security needs of cloud computing, ZTE built in the switch firewall module, can fully filter the internal subnet between the flow, to prevent the virus across the subnet attack. Highlight the security design, you can defend the "exhaustion of resources", "fake camouflage attack" and "equipment control rights attack" and so on, the network of common ARP attacks, deception, etc., can be perfect defense. In addition to the firewall module, also built-in DPI unit, DPI unit can detect 7 layer of application layer data flow, so that can effectively manage peer-to-peer and other traffic.

Green Energy Saving

As people pay more and more attention to the living environment, how to reduce the energy consumption, reduce the emissions of harmful substances, and deal with the climate warming become a hot spot in the world. Enterprises to achieve Low-carbon management will be the inevitable trend, it is green will become an enterprise to build IT environment is a very important link. Can you imagine? Last year China's IT industry used energy equivalent to the entire Three Gorges a year of power generation! How to better energy saving and emission reduction, how to achieve "green it" will become a research hotspot. On the one hand, ways to reduce the use of mobile phones, PCs, servers, such as the use of server virtualization technology, cloud computing technology, can greatly reduce energy consumption, efficiency can be greatly improved. On the other hand, the development of green energy-saving products can also achieve the purpose of energy saving and emission reduction.

ZTE is one of the first communication equipment manufacturers to start green energy-saving network research, has launched the green energy-saving ZXR10 Series Ethernet Switch products. Through advanced architecture design, the use of highly integrated devices, advanced chip production technology, intelligent fan speed control, intelligent power, single board and port power adjustment, such as a series of technologies to achieve energy saving and consumption. ZTE Core Switch ZXR108908 as an example, full time maximum power of 1200W, which than the industry's main core switch 4000w~6000w power-saving 60%~70%, the annual equipment at least 20,000 degrees of electricity savings, this does not include low power in the room air-conditioning equipment savings parts. With advanced design, with high bandwidth, high security, high availability, low energy consumption, easy management and other characteristics, ZTE's Ethernet switch will be in the era of cloud computing, the first to dominate.
