Embodiment Construction
[0043] The present invention is not limited by the following examples, and specific implementation methods can be determined according to the technical solutions of the present invention and actual conditions.
[0044] Below in conjunction with embodiment and accompanying drawing, the present invention will be further described:
[0045] as attached figure 1 Shown, the method for multi-path simultaneous transmission in this wide-area backup protection is carried out according to the following steps:
[0046] Step 101, establishing no less than two paths between two communication sites;
[0047] Step 103: Predict the time delay and bandwidth of each path, compare the time delay and bandwidth of the alternative path with the time delay and bandwidth of the main path respectively, and obtain the path evaluation value. The evaluation formula is shown in formula 1,
[0048] (1)
[0049] in, for the path The path evaluation value of ,in P...
