....for transporting tra#c flow. When a failure occurs, the a#ected working paths will switch their traffic flow to the corresponding backup paths. In this work, we consider the end to end path restoration that has been widely cited to be more advantageous than a link restoration scheme [2] 10] [16]. In order to increase the bandwidth utilization, the backup capacity is allowed to be shared among independent paths [17] 22] By using the terminology in references [9] 17] the backup sharing scheme, VP SH (Virtual Path Self Healing) can always reach better capacity usage than no sharing ....

....dependency between the working path routing, the backup path routing, and spare capacity sharing, obtained solutions are not optimal if they are treated separately. Murakami and Kim consider the routing of planning working and backup paths simultaneously and allowed backup capacity sharing [15] [16]. They formulate the survivable VP planning problems as continuous flow problems. One problem for using flow formulation is that it violates the VP integrity by assuming the VP to physical capacity ratio to be very small [15] This assumption is not always true in reality. Kawamura et al. give a ....
