Title:
RESOURCE-AWARE BACKUP NODE ALLOCATION ALGORITHM FOR SERVICE CHAIN, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/148605
Kind Code:
A1
Abstract:
Disclosed are a resource-aware backup node allocation algorithm for a service chain and a device. The algorithm comprises: building a mathematical model for a resource-aware service chain-backup problem, so as to obtain a problem formula for finding an optimal solution according to the service chain-backup problem and a condition of an optimal backup solution; obtaining a variable range of a variable in the mathematical model according to the problem formula for finding an optimal solution, wherein the variable is a number of backup nodes allocated to each VNF in a service chain; and acquiring an optimal solution according to the variable range of the mathematical model by means of differential optimization, so as to obtain a backup node allocation result of the service chain. The algorithm minimizes resources occupied by backup nodes while meeting an overall reliability requirement of a service chain.
