Edge routes must be upgraded along with the core layer.

New requirements of marginalized Networks

In order to meet people's increasing network needs, networks that provide constantly enriched services are bound to the development of marginalized networks. Edge users are increasingly involved in promoting the development of networks. In this case, the Broadband Access Router must be able to provide integrated access to smart services. In the future, the network should be a borderless network. Users can access the network anytime, anywhere to obtain the desired resources. Therefore, broadband access routers should be more flexible to meet different access methods, such as xDSL access, Ethernet Access, and wireless access.
"Three-in-one" is the development trend of network convergence in the future. As a marginalized access device, it should have video, voice, and data access functions, and have both QoS skills, it can well perceive network changes and control network traffic, and provide high-quality access capabilities for the network.
In addition, with the increasingly clear requirements of IPv6 technology in the construction of networks by operators and the formation of relevant standards, the support for IPv6 by broadband access routers is also very realistic.
Access should be matched with core development
To adapt to the future development of the network, the performance improvement of the Broadband Access Router cannot be ignored. Otherwise, the entire network may not be balanced. The harmony of the network is reflected in the performance, and the core network performance is constantly improved. Therefore, the access network performance must be improved accordingly. This is like the core network is a trunk, and the access network is the trunk limbs, the trunk continues to grow tall, it is inevitable that the limbs must continue to enrich the growth, so that it can be called a harmonious development. A harmonious network can reflect the beauty of harmony. Specifically, the Broadband Access Router needs to use an intelligent Core Engine to achieve 10 M Ethernet line rate processing capability in terms of forwarding performance. In terms of security, it fully cooperates with the development and application of VPN technology, supports multiple IPSec connections and 5 Mbps of professional hardware encryption.
The backbone layer router is the core device of the entire network. It is famous for its powerful data forwarding capabilities, massive route entries, and end-to-end precision QoS control capabilities. High-Speed interfaces are essential weapons. Compared with the high-speed interface of the core router in the backbone layer, the low-speed, flexible, and rich service interfaces of the Broadband Access Router are essential conventional weapons. The rich service interfaces can fully meet the needs of different user groups, flexible Deployment and flexible access fully protect users' existing investment.
Development Direction of broadband Routing
The Broadband Access Router is a low-end device, but it does not mean that the Broadband Access Router only has low performance and simple access. In the future, the low-end devices should have high performance to work with the increasing backbone network performance, paves the way for the generation gap between the access network and the core network. At the same time, the Broadband Access Router should absorb the high reliability, high security and other design concepts of high-end devices, and migrate high-end technologies to low-end devices, so that their high-tech content can be increased to better meet network needs.
Convergence and combination are the foundation of the development of broadband access routers, the continuous integration and combination of wireless technology, routing technology, firewall technology, L2 switching technology, voice technology, and even video technology will make the Broadband Access Router more and more open to multiple types of fixed interfaces and desktop devices. development. Such a development trend will inevitably emerge with a variety of forms of access routers.
In recent years, more and more key services have been hosted in IP networks, such as finance, network management, OA, decision support, voice, and video. Such application changes require 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 the threshold service features that must be supported by broadband access routers.
In addition to high security and reliability, broadband access routers require user management (AAA), Business differentiation and marking (stream classification), and security management (Business differentiation and isolation), multicast, mpls vpn, and other services must be supported, as well as IPv6 support in the future. In addition, it is important to emphasize the smooth upgrade capability of the Broadband Access Router to the business.
In addition, with the construction of China Unicom's comprehensive business access to broadband networks, broadband access routers need to support more diverse broadband access methods, such as XDSL, LAN, Cable, and WLAN, it will also extend to the small and medium-sized office environment and home network environment, which will provide a broader space for the development of routers.
