| Abstract | In this thesis, we propose three approaches for dynamic survivable traffic grooming with p-cycle protection: fixed routing with single-hop traffic grooming (SH), fixed routing with multi-hop traffic grooming (MH) and fixed alternate routing with multi-hop traffic grooming (MHa). The three approaches are evaluated and compared through computer simulation. Numerical results show that, under the limitation of no disruption of established p-cycles (NoD), MHa yields the best performance among the three approaches. However, when re-optimization of established p-cycles (ReO) is allowed, the performances of the three approaches are not significantly different. While the performances of these three approaches with ReO are better than those with NoD, the approaches with ReO use more runtime. However, even with NoD, optimization of pcycle assignment is still time consuming since it involves integer linear programing (ILP). Therefore, we develop heuristic that can reduce the runtime with its performance not significantly different compared with NoD. |
