Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments, with the understanding that these embodiments are merely provided to enable those skilled in the art to better understand and practice the invention and are not intended to limit the scope of the invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Accordingly, the present disclosure may be embodied in the following forms, namely: complete hardware, complete software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Explanation of terms that may be involved in the embodiments of the present invention:
SPF algorithm: the SPF algorithm is the basis of the OSPF routing protocol. The SPF algorithm, sometimes also referred to as Dijkstra algorithm, uses each router as a ROOT to calculate its distance to each destination router, and each router calculates the topology of the routing domain from a unified database, which is similar to a tree, referred to as the shortest path tree in the SPF algorithm. In the OSPF routing protocol, the trunk length of the shortest path tree, i.e., the distance from the OSPF router to each destination router, is called the Cost of OSPF, and the algorithm is: cost=100× (10)/(6)/link bandwidth.
OSPF protocol: the OSPF protocol is a link state protocol. Each router is responsible for discovering and maintaining the relationship with neighbors, describing a known neighbor list and a known link cost LSU (Link State Update) message, and learning the network topology structure of the whole autonomous system through periodic interaction between reliable flooding and other routers in the autonomous system AS (Autonomous System); and the router of the autonomous system boundary is used for injecting the routing information of other AS, so AS to obtain the routing information of the whole Internet. The LSA is regenerated every specific time or when the link state changes, and the router advertises the new LSA through a flooding mechanism so as to realize real-time update of the route.
IGP protocol: is a protocol for exchanging routing information between gateways (hosts and routers) within an autonomous network. The routing information can be used in an Internet Protocol (IP) or other network protocol to describe how the routing is performed. The IGP protocol includes RIP, OSPF, IS-IS, IGRP, EIGRP. Currently, the IS-IS and OSPF protocols are commonly used for operator networking.
ISIS-IS (Intermediate System-to-Intermediate System, intermediate System to intermediate System) routing protocol initially was a dynamic routing protocol designed by ISO (the International Organization for Standardization, international organization for standardization) for CLNP (Connection Less Network Protocol, connectionless networking protocol).
