一种保证NFV可靠性的最优备份拓扑生成方法
Optimal backup topology generation approach to guarantee reliability of NFV
摘要
Abstract
Like traditional virtual network,the problem of reliability will exist when the SFC is mapped to the underlying network by NFV technology.Based on the SFC topology design and mapping,this paper added a backup topology to improve the survival rate of the single link failure in NFV environment and simplified the backup topology with less resource consumption.Then it put forward two kinds of optimal backup topology generation algorithms in view of whether the service path could be separated.Simulation experiments show that the optimal backup topology can reduce the cost of backup bandwidth resources effectively and improve the efficiency of resource utilization based on improving the reliability.关键词
