自适应服务功能链动态调整策略研究

Research on Strategies for Dynamic Adjustment of Adaptive Service Function Chain

服务功能链动态调整是应对网络变化、提升服务性能的重要方法。本文提出了一个基于带内网络遥测的服务功能链动态调整方案,通过带内流量采集服务功能链流信息,实时发现并调整性能下降的服务功能链。实验结果表明,该方案在请求接受率、资源利用率等方面都明显优于传统方案。

Dynamic adjustment of service function chain is an important method to respond to network changes and improve service performance.This article proposes a dynamic adjustment scheme for SFC based on in band network telemetry.By collecting SFC flow information through in band traffic,SFC with degraded performance can be detected and adjusted in real-time.The experimental results show that the proposed scheme in this article is significantly superior to traditional schemes in terms of request acceptance rate and resource utilization rate.
