II-C) Recovery schemes GR LR RLR FLR EkFLR UR P (Theorem 1) P (Theorem 1) P (Theorem 1) P (Theorem 1) P (Theorem 1) P (Theorem 1)????? P (Theorem 6) P (Theorem 6) P (Theorem 6)???? TABLE I SUMMARY OF THE COMPUTATIONAL COMPLEXITIES OF THE PROBLEMS The target function is to maximize the total gained profit: Maximize f w f x f subject to the following constraints: (C-1) e=(u,v) yēfe x f v = t f e=(v,u) yēfe = x f v = s f 0 else v V, f F, ē {E,φ} (C-2) f d f yēfe u e e E, ē {E,φ} (C-3) y φ fe =0 f F, e / P f (C-4) yfe e =0 f F, e E (C-5) 0 x f 1, 0 yēfe 1 e E, ē {E,φ}, f F. The set (C-1) of constraints ensures flow conservation. The set (C-2) ensures that no edge carries more than its capacity. The set (C-3) ensures that when no failure occurs, each flow is routed only along its primary LSP. The set (C-4) ensures that no flow is routed over a failed link. Finally, the set (C-5) of constraints ensures that the total routed bandwidth of each flow and the routed bandwidth on each backup LSP do not exceed flow demand. Each of the recovery schemes presented in Section I imposes a set of additional constraints on the backup LSPs. We now present the specific set of constraints for each recovery scheme. The specific set of constraints for the LR scheme is: (LR-1) yēfe yφ fe f F, ē E,{e e E,e ē and e is not a downstream edge of ē along P f }. The above set of constraints ensures that the backup LSP of f for ē =(u, v), assuming ē P f, will follow the primary LSP all the way from the source to u. From node u to the destination node, the backup LSP is not constrained. The specific set of constraints for the RLR scheme is: (RLR-1) yēfe yφ fe f F, ē E,{e e E,e ē}. RLR-1 is similar to LR-1, except that it also ensures that if a backup LSP protects against a failure of edge ē =(u, v), it will follow the primary LSP not only from the source to u but also from v to the destination. Since S-PRFP allows the traffic of the failed primary LSP to be split between several backup LSPs, RLR may use an unbounded number of backup LSP for each link failure. Hence, it is easy to see that an optimal solution for the FLR scheme and for the EkFLR scheme can be produced from an optimal solution for the RLR scheme. Hence, there is no need to specify special constraints for these two recovery schemes. The specific set of constraints for the GR scheme is: = 0 (GR-1) yēfe y φ fe (GR-2) yēfe yφ fe = yēfe f F, ē, e E (GR-3) yē1 fe = yē2 fe ē E,{f f F, ē P f },e P f otherwise f F, ē 1, ē 2 P f where ē 2 immediately follows ē 1 on P f, e E. The set (GR-1) of constraints ensures that the backup LSPs of every flow whose primary LSP crosses the failed edge must be edge disjoint with the primary LSP. The set (GR-2) introduces auxiliary variables yēfe. Each of these variables represents the difference between the bandwidth of f routed on the primary LSP, and the bandwidth of f to be routed on the backup LSPs that protect the flow against the failure of edge ē. Theset(GR- 3) of constraints ensures that for each flow the same set of backup LSPs is used to protect all the edges along the primary LSP. Finally, the set of specific constraints for the UR scheme is: (UR-1) yēfe yφ fe ē, e E, f F, ē/ P f. This set ensures that if the failed link is not included in the primary LSP of a flow, then the backup LSP is identical to the primary LSP. Otherwise, the set of backup LSPs has no constraint. B. The Unsplittable Primary-restricted Restorable Flow Problem (U-PRFP) We now address the Unsplittable Primary-restricted Restorable Flow Problem (U-PRFP). There are two differences between U-PRFP and S-PRFP. First, in U-PRFP, a profit can be obtained for a flow only when its entire demand is satisfied. Second, in U-PRFP, the traffic of each flow can be restored using only a single backup LSP. We now address the computational complexity of U-PRFP.
