摘要

网络功能虚拟化(NFV)与软件定义网络(SDN)相结合，既创造了新的机遇，也带来了巨大的挑战，比如业务功能链(SFC)延迟的增加和吞吐量的降低。在本文中，我们提出了HybridSFC，这是一个框架，探索了在流量级别和网络功能(NF)级别并行数据包处理的机会。它结合了创新的控制和数据平面机制，将一个顺序链划分并转换为几个(细粒度的)sfclet，这些sfclet可以在多个核心和服务器上并行执行。HybridSFC是实用的，因为它可以处理跨多个服务器的NFs，并且不需要修改现有的NFs。实验表明，HybridSFC将延迟降低了51%，CPU开销为7%，整体系统吞吐量提高1.42×-1.87×。

HybridSFC: Accelerating Service Function Chains with Parallelism

Network Function Virtualization (NFV) coupled with Software Defined Networking (SDN) creates new opportunities as well as substantial challenges such as increased Service Function Chain (SFC) latency and reduced throughput. In this paper, we present HybridSFC, a framework that explores the opportunities of parallel packet processing at both traffic level and Network Function (NF) level. It incorporates innovative control and data-plane mechanisms that partition and convert a sequential chain into several (finer-grained) SFClets that can be executed in parallel on multiple cores and servers. HybridSFC is practical in that it can handle NFs spanning multiple servers and requires no modifications to existing NFs. Experiments show that HybridSFC reduces latency up to 51% with 7% CPU overhead, and a 1.42×-1.87× improvement in overall system throughput.
