Patent ID: 7570638

Claim:
An information processing method executed by a management server that manages paths between arbitrary nodes in a specific domain, comprising: detecting an event in which a path is constituted between a source address associated with said specific domain and a destination address associated with a second domain different from said specific domain; constituting a plurality of paths between a first node associated with said source address and a second node associated with said second domain and included in said specific domain; identifying, as registered paths, a number of paths based on bandwidth information of said plurality of paths; storing said source address, said destination address and data concerning said registered path for each said registered path into a path data storage; transmitting, to a management server in a third domain connected to said second node, a constitution request including said source address and said destination address, and including, for each said registered path, data concerning bandwidth of said registered path and data concerning said second node; receiving constitution information including said source address and said destination address, and including, for each said registered path, data concerning a connection link between said second node and a connection node on the third domain side from said management server in said third domain; storing said data concerning said connection link into said path data storage, in association with a combination of said source address, said destination address, and said data concerning said registered path; and carrying out setting for routing to nodes associated with said registered path in said specific domain by using data stored in said path data storage.
