Abstract:
In real networks, the link between two adjacent nodes always has
multi-fibers. The 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-fiber 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 will 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.
