The invention provides a network protection method and a network protection architecture. In a network, one or more protected local networks are determined according to practical situations and a protection characteristic set of the local network is set; a link in the protected links of the protection characteristic is set as a protection link; and whether a protection switching request exists is judged, if the protection switching request does not exist, a node to which the protection link belongs blocks a port connected with the protection link; and if the protection switching request exists, a node of the protection switching request blocks a designated port of the protection switching request, and the node to which the protection link belongs unblocks the port connected with the protection link. This solution is suitable for networks with various kinds of topologies, when a protocol channel of a protection protocol for a transmit path of a protocol frame indicating the existence of the protection switching request is set up in the protection characteristic set, the protection protocol is prevented from being implemented on each node. |
