The architecture of the border routing system is an innovative software technology that interests Wide Area Network (WAN) designers. This technology can greatly simplify full-featured routing on the WAN perimeter. Therefore, it will first make it a reality to reduce the expensive WAN maintenance costs. In addition to the software advantages of the border routing, the border routing can save the cost of accessing the remote hardware related to the routing without limiting the protocols supported.
The so-called border routing is to regard the standard routing software as a n-path local route, and extend the LAN part of the software to the WAN. This will lead to a new set of remote routers, which greatly simplifies the routing software features.
In other words, border routing regards the central and remote devices as a single system. The innovation to solve the routing problem provides all the advantages of configuring only one interface, this interface is very similar to a central device in a centralized Backbone Network LAN environment, but in a large WAN network. The management complexity is reduced because the WAN port of the center or remote router is rarely required.
The software innovation of border routing adds the advantages of simplicity and low cost to the hardware advantages related to access routers, but it does not limit the selection of routing protocols at remote points.
Border routing transfers the complexity of route management to a Routing Management Center to simplify the management of routers. With border routing, network administrators can quickly and effectively manage multiple remote locations. If the WAN connection needs to be transferred from the border route to the normal route, the software upgrade tool can quickly convert a remote border routing device to a normal router. Border routing supports the following powerful route improvement capabilities:
Data Compression allows larger information traffic to be carried on low-speed lines and significantly reduces WAN costs.
Services to prioritize data so as to accelerate the processing of key applications.
Filters can be set flexibly to provide network security and traffic control.
Exchange line support, including support for Frame Relay, ISDN, dial-up lines, and X.25, to reduce the cost of remote office WAN connections.
Fault recovery capability. When the router detects a fault in the main line, it can provide dial-up backup.
Powerful Network Management Based on proxy identification of the entire system.
Border routing technology integrates most router operations so that several full-featured routers in the Central Office can provide services for low-cost routers on the periphery of the network to reduce the cost of equipment purchase.
