NFV弹性控制中的流迁移优化 ABSTRACT 基于动态创建和移除网络功能实例,NFV在网络功能控制上有很大的弹性.比如,网络功能和并,网络功能拆分,负载均衡等等. 那么为了实现弹性控制,就需要网络流量的重新分配.那么问题来了:哪些流量适合迁移,哪些流量不适合迁移? 这篇论文介绍了他们所编写的OFM控制器:优化了NFV弹性控制中的流迁移. 1. INTRODUCTION 刚刚也提到了,为了实现弹性控制(合并.拆分.负载均衡),我们需要一个有效的策略来控制流的转向.正好,SDN架构可以控制流的方向…

Transparent Flow Migration for NFV 摘要 因为SDN提供的灵活性,NF之间存在着流量的迁入和迁出问题.而且NF也要根据相关的状态信息处理数据包,所以流量迁移必须满足以下两点要求: 保持数据包和状态的迁移顺序,必须获取状态才能处理数据包. 想都不用想,这点一定是低开销.低时延- 目前现有的流量迁移架构,把流量迁移和状态迁移耦合在一起,这种架构不能实现安全.高效.低开销的迁移. 于是本篇论文提出了一个流量迁移架构,叫TFM(Transparent Flow Migr…
