Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments, which should be understood to be presented only to enable those skilled in the art to better understand and implement the present invention, and not to limit the scope of the present 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.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
The terms that may be involved in the embodiments of the present application explain:
SPF algorithm: the SPF algorithm is the basis of the OSPF routing protocol. The SPF algorithm, sometimes also referred to as Dijkstra algorithm, calculates the distance from each router to each destination router using each router as a ROOT (ROOT), and calculates a topology structure diagram of the routing domain from a unified database, the structure diagram being similar to a tree, and in the SPF algorithm, referred to as a shortest path tree. 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 OSPF Cost, and its algorithm is: cost 100 x (10) 6/link bandwidth.
OSPF protocol: the OSPF protocol is a link-state protocol. Each router is responsible for discovering and maintaining the relation with the neighbor, describing a known neighbor list and a Link State Update (LSU) message, and learning the network topology structure of the whole autonomous system through the reliable periodic interaction of flooding and other routers in the autonomous system AS (autonomous System); and the router at the boundary of the autonomous system is used for injecting the routing information of other AS, thereby obtaining the routing information of the whole Internet. Every other specific time or when the link state changes, the LSA is regenerated, and the router advertises the new LSA through the flooding mechanism so as to realize the 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 specify how routing is to be performed. IGP protocols include RIP, OSPF, IS-IS, IGRP, EIGRP. At present, the operator networking commonly uses IS-IS and OSPF protocols.
IS-IS (Intermediate System-to-Intermediate System) routing Protocol was originally a dynamic routing Protocol designed by ISO (the International Organization for Standardization) for CLNP (Connection Less Network Protocol).
LSPID, the unique identification of the local terminal equipment.
NeiLspid is the unique identifier of the opposite terminal equipment.
According to the embodiment of the invention, the device offline warning method and device based on the IGP-SPF algorithm are provided, the real-time network state of the device can be rapidly acquired by collecting real-time link information through the IGP-SPF algorithm and analyzing the real-time link information, whether the current device is offline or not is positioned, and a warning process is triggered to notify maintenance personnel, so that the purposes of real-time and high efficiency are achieved.
