Abstract:
Currently, most route computing algorithms only compute a shortest or
an optimal path.The results of this computation just refer to link
level, without consideration of fibers. But, in real networks, the
link between two adjacent nodes always has multi-fibers. This
condition above happens more frequently especially for the gateway
nodes in the multi-domain network. Moreover, the number of links
between two adjacent domains is always more than one. From the view
of parent PCE, the two conditions above will be regarded as the
problem of multi-fibers between adjacent nodes. However, most route
computing algorithms always can not solve the problem of multi-fiber
between adjacent nodes. As a result, parent PCE can not compute the
route sequence with specific fibers. It brings distress and problems
when parent PCE computing the loose route sequence.
In order to solve the problems existing in real networks, an
efficient solution will be proposed for parent PCE facing the multi-
fiber between adjacent nodes. Some interface and structure will be
expanded in this proposal.
