Survivable virtual network mapping (SVNM) has been extensively investigated to guarantee that the mapped virtual network (VN) works normally against substrate failures. The existing studies of SVNM mainly focus on single node or single link failure. Since natural disasters usually cause severe substrate failures in geographic regions, some work addressing SVNM against regional failures has been studied...
Network virtualization has been regarded as a core attribute of the Future Internet. In a Network Virtualization Environment (NVE), heterogeneous virtual networks can share the same physical infrastructure regardless of their different topologies, demands, protocols and so on. In this case, the Survivable Virtual Network Embedding (SVNE) problem becomes increasingly critical to overcome the failure...
In this paper, a novel scheme for MSOT scenario (multi-service on one terminal)using link sharing to guarantee service continuity is proposed. Fuzzy control theory is applied for designing the sharing strategy. The functionalities of mobile terminal for link sharing are modular design considering easy implementation. The performance of the proposed algorithm is analyzed and compared with fixed percentage...
