Embodiment Construction
[0047] The specific implementation of the method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0048] After a linear multiplex section protection group or a two-fiber bidirectional multiplex section sharing protection ring is configured on an ASON network, and a unique protection group identifier is configured, LMP associates the protection attributes and protection group identifiers as link attributes to the corresponding link Then, the traffic engineering link is sent to the routing protocol in the form of traffic engineering link. The routing protocol then floods the traffic engineering link and the attributes of the traffic engineering link in the entire network, and finally the topology of the entire network converges. The above are the common steps adopted by the method of the present invention, so they will not be repeated in the description of specific embodiments.
