What does boundary routing mean and what are its benefits?
Boundary routing system architecture is an innovative software technology that is of great interest to wide area network (WAN) designers, which can greatly simplify full-function routing across the WAN periphery. Therefore, it will first make it a reality to reduce the expensive WAN maintenance costs. In addition to the software advantages of boundary routing, boundary routing can also save access to remote hardware related to routing without limiting the supported protocols.
The so-called boundary routing is to regard standard routing software as n-path local routing and extend the local area network part of the software to the wide area network. This will result in a new set of routing software capabilities for remote routers.
In other words, boundary routing treats central and remote devices as a single system, and this innovation to solve the routing problem provides all the advantages of configuring only a single interface that is very similar to a central device in a centralized backbone LAN environment, but in a large WAN network. The complexity of management is reduced because there is little need to configure the WAN port of the center or remote router.
The software innovation of border routing adds the advantages of simplicity and inexpensiveness to the hardware advantages related to accessing routers, but it does not limit the choice of routing protocols at remote points.
Boundary routing simplifies router management by shifting the complexity of routing management to a routing management center; with boundary routing, network administrators can quickly and effectively manage multiple remote locations. If the WAN connection needs to be transferred from the boundary route to the usual route, the software upgrade tool can quickly convert a remote boundary route device to a normal router. Boundary routing supports the following powerful routing improvement capabilities:
·Data compression, which allows greater information flow to be carried on low-speed lines and greatly reduces WAN costs.
·Service class, implement data priority to accelerate the processing of key applications.
Flexible filtering to provide network security and traffic control.
·Switched 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, dial-up backup can be provided when the router detects a main line failure.
· Powerful network management based on proxy identification of the entire system.
Boundary routing technology reduces the cost of purchasing equipment by bringing together most router operations to several fully functional routers in the central office, enabling services to low-cost routers on the periphery of the network.
