The invention provides a network protection method and a network protection framework. Through a double-node protection mould of the invention, a part of networks needing to be protected on a provider backbone bridge traffic engineering (PBB-TE) tunnel which supports traffic engineering are provided with a protection domain consisting of a primary section and a standby section, so that a certain section and an end point bridge of a part of the PBB-TE tunnel are protected to the maximum extent. The PBB-TE segmented protection network framework provided by the invention realizes the partial segmented protection of the PBB-TE tunnel, protects a partial section needing to be protected and solves the problem that the entire Ethernet tunnel needs to be switched when a part fails. The method and the framework have the advantages of enhancing the utilization ratio and reliability of the network, achieving high flexibility on the protection of networking implementation and meeting common requirements during practical networking.
