ABSTRACT:
A communication network with a database consistency mechanism is disclosed, wherein a sequence number and a set of routing information for each of a set of virtual circuits of the communication network are maintained in a main database and an auxiliary database in each of a set of communication nodes in the communication network. The sequence numbers in the main database or the auxiliary database in each of the communication nodes are verified if one of the communication nodes switches between the main database and the auxiliary database, and then virtual circuits are rerouted when necessary.
