Abstract
A method and system for managing protocol connection in a PBB network and a BEB node. A first BEB node in the PBB network receives a Pseudo Wire (PW) connection requesting message sent by a second BEB node which has a PBB instance. When it is determined according to the PW connection requesting message that the first BEB node has the same PBB instance as that of the second BEB node, the first BEB node sends a PW response message back to the second BEB node and establishes protocol connection between the first BEB node and the second BEB node for forwarding backbone frame.
