Enhanced Reliability in Network Function Virtualization by Hybrid Hexagon-Cost Efficient Algorithm
چکیده
In this,communication world, the Network Function Virtualization concept is utilized for many businesses, small services to virtualize network node function and build a block that may connect chain, communication services. Mainly, Virtualized Forwarding Graph (VNF-FG) has been used define connection between VNF give best end-to-end existing method, mapping backup were proposed but there was no profit reliability improvement of primary VNF. As consequence, this paper offers Hybrid Hexagon-Cost Efficient algorithm determining among multiple backing up VNF, lowering costs while increasing dependability. The chosen based on highest cost-aware important measure (CIM) rate, which assess relevance forwarding graph.To achieve optimal cost-efficiency, with maximum CIM selected. After selection process, updating processed by three steps include one from SFC, two Service Chain (SFC),and different SFC. Finally, method compared CERA, MinCost, MaxRbyInr cost, number PN nodes, SFC request utility, latency. simulation result shows cuts down cost computation time 57% 45% CER scheme improves cost-efficiency. result, system achieves less high reliability, low consumption can improve operation.
