Embodiment Construction
[0027] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0028] In this embodiment, a method for deleting a link state notification is provided, image 3 is a flowchart of a method for deleting a link state notification according to an embodiment of the present invention, such as image 3 As shown, the process includes the following steps:
[0029] Step S302, when the duration of the first LSA reaches a first preset value, determine whether the first LSA is in the retransmission list of the neighbor;
[0030] Step S304, if the first link state announcement is not in the neighbor's retransmission list, then obtain the number of neighbors in the database digest exchange phase and the number of neighbors in the database synchronization completion phase with...

The invention discloses a method of deleting a link state advertisement and an apparatus thereof. The method comprises the following steps of when an existed time length of a first link state advertisement reaches a first preset value, determining whether the first link state advertisement is in a neighbor retransmission list; if the first link state advertisement is not in the neighbor retransmission list, acquiring the number of neighbors which are in a database abstract exchange phase and the number of neighbors which are in a database synchronization completion phase in a propagation scope of the first link state advertisement; if the number of the neighbors which are in the database abstract exchange phase equals to the number of the neighbors which are in the database synchronization completion phase, deleting the first link state advertisement. By using the method and the apparatus of the invention, a problem that parts of LSA which can be deleted can not be deleted so that resource wastes are caused in a correlation technology is at least solved.
Description
technical field [0001] The present invention relates to the field of communications, in particular to a method and device for deleting link state notifications. Background technique [0002] There are two main types of dynamic routing protocols, one is the distance vector routing algorithm, and the other is the link state routing algorithm. Distance vector routing algorithms include Routing Information Protocol (Routing Information Protocol, referred to as RIP), Border Gateway Protocol (Border Gateway Protocol, referred to as BGP), link state routing algorithms include Open Shortest Path First (OpenShortestPathFirst, referred to as OSPF), intermediate system-intermediate System (Intermediate System-to-Intermediate System, referred to as ISIS). In the distance vector routing algorithm, each router maintains a table, which lists the currently known best path to each destination, and these tables are constantly updated by exchanging information between neighbors, and finally e...
