Complex dynamic routing analysis method for realizing telecommunication network based on intelligent routing simulation technique

The invention relates to a complex dynamic routing analysis method for realizing a telecommunication network based on the intelligent routing simulation technique. A BGP router is simulated by a software program at a monitoring host computer and is only used for monitoring all neighbors and does not forward BGP packets of the neighbors; the software router configures the neighbors at a front page; the router receives and analyzes the update information transmitted by the neighbors and writes the information into a local routing table and a database after shaking hands with the neighbors through open information, but does not broadcast the local routing table to the neighbors, so that the neighbors can not know the reachable destination network through a local software router, and the neighbors can not transmit a BGP protocol packet to the local software router for the forwarding service; and the software router adopts the steps for configuring monitoring neighbors: after a user edits the increase of neighbors, elimination of the neighbors and edition of the neighbor's information on the front page of the software router, the configuration of BGP neighbors is realized through TCP connection to transmit the BGP background of the monitoring host computer.
