Abstract

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