Analysis on the Development of IP routers in the New Situation

There are many things worth learning about IP Routers. Here we mainly introduce vrouters under the changing trend of IP networks, including the trend of exchange capability towards sea quantization and clustering. The Multi-Service bearer of an IP network has the advantages of uniform protocols and interfaces. It can quickly expand services, simplify network layers, reduce costs of construction, O & M, and business marketing services, and simplify customer relationship management, therefore, a Unified IP bearer network can support larger business economies of scale.

To adapt to this change, the traditional IP bearer network must be changed to achieve the goal of Multi-Service bearer. As the main equipment of the IP network, the security, availability and reliability of the IP router have an important impact on national security, industrial development, and social information construction.

IP router under the IP network Change Trend

In recent years, due to the widespread use of IP networks and the new demands for Multi-Service bearer of IP networks, IP router equipment has the following new development trends.

High-speed Interfaces

At the beginning of the design, IP router equipment has a major role, that is, to adapt to high-speed LAN and low-speed Wan. As technology advances, IP Routers become the core devices of the IP network. IP routers require increasingly high-speed interfaces to construct a broadband backbone network. Currently, commercial IP routers have reached 40 Gbit/s, and the lab has already exceeded 100 Gbit/s, which is about to reach the electrical signal processing limit.

Exchange capability tends to quantify and cluster by sea

With the rapid development of information technology, the business carried by the communication network is becoming more and more abundant, especially the rapid growth of IPTV, mobile voice, P2P and other services. Backbone Networks require more and more bandwidth. In the past few years, the growth rate of China's trunk line business volume and bandwidth demand has exceeded 200%, and the annual growth rate is expected to reach about 100% in the next few years. Therefore, the IP backbone network is facing the pressure of frequent upgrades and resizing, and scalability has become an important bottleneck for sustainable development.

The most critical issue in the expansion of the IP backbone network is the expansion of the Core IP router capacity. With the rapid growth of backbone network services, the IP network infrastructure needs to be fully upgraded every two years. operators can no longer bear this frequent network upgrade, A new generation of ultra-high-capacity IP routers is urgently needed. This kind of "sustainability" is mainly reflected in two aspects. First, capacity sustainability: the system capacity can be continuously and smoothly upgraded to meet the operator's business growth needs for a long time in the future. Second, hardware sustainability: there is no need to replace the original equipment for capacity upgrades. All hardware can be used continuously to minimize the impact of upgrades on the business.

Pay more and more attention to security issues

Network security includes network security, network service provision security, network user information security, and harmful information control. As the main device of the network, the IP router has a direct relationship with network security, which can also protect the information security of network users.

The initial security of IP router equipment mainly focuses on the reliability of network equipment, backup of important parts, electrical characteristics of network equipment, and performance indicators of network equipment. As the Internet grows and technology advances, network security has new requirements for IP router devices. At the control level, security should be guaranteed in terms of controlling information access control, controlling information identification, controlling information availability, controlling information non-repudiation, controlling information communication security, and controlling information integrity and privacy.
