Border node barrier and method for establishing a connection between nodes border barrier

摘要

Border node a block comprising a connection controller (20), a resource manager link (21) and a controller travel (22), the border of block block information node on conversion wavelength, characterized in that, the connection controller (20) is configured to send a request to query block information to the administrator (21) of connection resources after receiving a request message connection, check and verify information block point input the subnet of a local terminal, check information block an exit point of the subnet of an egress border node once it has passed the verification and submit a request for consultation travel to running controller using information block entry point for the local subnet and information terminal block exit point of the subnet node exit border as query parameters; administrator (21) of connection resources is configured to feed information block entry point of the subnetwork local terminal back to the connection controller (20) in response to the request to query information block controller connection (20); and the path controller (22) is configured to provide travel information to establish a connection in response to the request from the route; wherein the information block entry point of the subnetwork comprises interchangeability between the entry point of the subnetwork and other parts of the subnet local terminal in a domain route, and information block exit point the subnet includes the interchangeability between the exit point of the subnet and other parts of the subnet egress border node in the domain of travel.
