摘要：A network design apparatus includes: a first processing unit configured toselect one or more paths between nodes in response to a request for a bandwidth

between pairs of nodes in a network to determine working communication routes andprotecting communication routes connecting the pairs of nodes, and estimate a numberof communication lines in the selected path; and a second processing unit configured toallocate logical channels of the communication lines to the working communicationroutes and the protecting communication routes based on the requested bandwidth,wherein the first processing unit determines the protecting communication routes whilepermitting the sharing of the path, and the second processing unit allocates a commonlogical channel to one or more communication routes, out of the protectingcommunication routes, that share the path and are not simultaneously used when afailure occurs in the working communication routes.
