Editor's note: In recent years, broadband backbone networks have developed rapidly, and the access network connecting users and core networks has become a bottleneck in the development of broadband services due to various conditions. Edge routing with higher speed, higher performance and higher security has become the first choice for users.
New requirements for marginalized networks
In order to meet people's growing network needs, as a network that provides continuous enrichment of services, it is inevitable that it will develop towards a marginalized network, and edge users are increasingly involved in promoting the development of the network. In this case, the broadband access router needs to be able to provide integrated intelligent services access. The future network should be a borderless network, where users can access the network anytime, anywhere to obtain the resources they want. Therefore, the broadband access router should be more flexible to meet different access methods, such as xDSL access, Ethernet access, wireless access, etc.
"Three networks in one" is the future development trend of network convergence. As a marginalized access device, it should have access functions for video, voice and data. At the same time, it has QoS skills, which can well perceive network changes and control network traffic, and provide high-quality access capabilities for the network.
In addition, as operators' requirements for IPv6 technology in building networks become clearer and more relevant standards are being formed, and broadband access routers support IPv6 is also very realistic.
Access should be developed in line with the core
In order to adapt to the future development of networks, the performance improvement of broadband access routers cannot be ignored, otherwise it will cause unbalanced development of the entire network. The harmonious beauty of the network is reflected in performance. The continuous improvement of the core network performance will inevitably require corresponding improvement in the performance of the access network and then coordinate development. This is like the core net is a torso, and the access net is the limbs of the torso. When the torso continues to grow, it must also continue to grow in full bloom, so that it can be called harmonious development. Only a harmonious development network can reflect the beauty of harmony. Specifically, broadband access routers need to use an intelligent core engine to achieve 10M Ethernet line speed processing capability in forwarding performance; they fully cooperate with the development and application of VPN technology in terms of security, and have the professional hardware encryption processing capability of multiple IPSec concurrent connections and 5Mbps.
The backbone layer router equipment is the core device of the entire network. It is known for its advantages such as powerful data forwarding capabilities, massive routing table entries, and end-to-end fine QoS control capabilities. High-speed interfaces are its essential weapon. Compared with the high-speed interface of the backbone core router, the low-speed, flexible and rich service interfaces of the broadband access router are necessary conventional weapons. The rich service interfaces can fully meet the needs of different user networks, and flexible deployment and flexible access fully protect users' existing investments.
Development direction of broadband routing
Broadband access routers are low-end devices, but they do not mean that broadband access routers only have low performance and simple access. Future low-end devices should have high performance to match the increasing backbone network performance and pave the generation gap between the access network and the core network. At the same time, broadband access routers should absorb the design concepts of high reliability and high security of high-end equipment, and migrate high-end technologies to low-end equipment, so that their own high technical content can better meet network needs.
Convergence and combination are the foundation of the development of broadband access routers. The continuous integration and combination of high technologies such as wireless technology, routing technology, firewall technology, layer two switching technology, voice technology and even video technology will inevitably lead to the development of broadband access routers to multiple types of fixed interfaces and desktop devices. Such a development trend will inevitably continue to emerge with rich access routers.
In recent years, more and more key businesses have been carried in IP networks, such as finance, network management, OA, decision support, voice, video, etc. This change in application requires broadband access routers to have high performance, high reliability, high security, and strict service quality assurance similar to high-end routers. MPLS VPN, multicast, voice, QoS and other services have gradually become threshold service features that broadband access routers must support.
In addition to requiring high security and reliability for broadband access routers, it requires support for user management (AAA), service distinction and tagging (stream classification), security management (service distinction and isolation), multicast, MPLS VPN and other services, and there is also future support for IPv6. In addition, it is important to emphasize the smooth upgrade capabilities of broadband access routers to services.
In addition, with the construction of China Unicom's comprehensive service access broadband network, broadband access routers need to support richer broadband access methods, such as XDSL, LAN, Cable, WLAN, etc., and extend to small and medium-sized office environments and home network environments, which will provide a broader space for the development of routers.
