Description
Technical Field
The invention relates to the technical field of routing tables, in particular to a method for establishing and monitoring a routing table on line.
Background
By routing table is meant a table stored on a router or other internet network device that stores paths to a particular network terminal and, in some cases, metrics associated with those paths. In computer networks, a routing table or routing domain information base (RIB) is a spreadsheet (file) or class database stored in a router or networked computer. The routing table stores the path (and in some cases, the route metric value of the path) that points to a particular network address. The routing table contains topology information of the network periphery. The main goal of routing table establishment is to implement routing protocols and static routing.
In modern router architectures, the routing table is not directly involved in the transmission of packets, but is used to generate a small lookup table containing only the packet transmission priority paths selected by the routing algorithm, which is usually compressed or compiled in advance for optimized hardware storage and lookup. The establishment process of the routing table is also an enumeration process, in the existing enumeration process, any two devices cannot be accessed through a maintenance package, and a monitoring system is not arranged in the establishment process of the routing table, so that the devices cannot be dynamically accessed and complete the configuration of a new node when going on and off, and when going off accidentally, the information of the devices in the network cannot be deleted for the devices which are accidentally going off the line.
