<p>A barrier boundary node and a method for establishing connection between barrier boundary nodes are disclosed. The barrier boundary node is composed of a connection controller, a link resource manager and a routing controller. The method includes steps that: an entrance boundary node queries and validates the barrier information of an entrance subnet point after receiving connection establishment request message, and sends a barrier information query request to an exit boundary node after validating successfully; the exit boundary node queries and validates the barrier information of an exit subnet point, and returns the barrier information to the entrance boundary node after validating successfully; the entrance boundary node takes the barrier information of the entrance subnet point and the exit subnet point as the querying parameter to query the routing, and sends connection request information to the exit boundary node after querying routing successfully; the entrance boundary node receives the connection confirming information returned by the exit boundary node, and then the connection establishment is completed. The method can effectively reduce invalid flood message and ensure the success rate of the connection establishment.</p> |
