摘要

在本文中，我们描述了一个运行在商用硅交换机上的分布式网络操作系统。多个交换机可以形成一个结构，用于独立于网络拓扑的编排和状态共享目的。fabric中的每个交换机通过TCP/IP与其他交换机共享其状态，并保持虚拟端口的全局视图以及拓扑结构，以做出单独的交换、转发和封装决策。这允许分布式交换机操作系统在虚拟机迁移和动态编排VXLAN覆盖时跟踪虚拟机，而不需要在服务器上进行软件覆盖。由于Switch OS将VXLAN的封装/解封装卸载到Switch ASIC上，因此没有性能损失。

Distributed control plane for high performance switchbased VXLAN overlays

In this paper, we describe a distributed network operating system that runs on merchant silicon based switches. Multiple switches can form a fabric for orchestration and state sharing purposes independent of the network topology. Each switch in a fabric shares its state with other switches over TCP/IP and keeps a global view of virtual ports along with topology to make individual switching, forwarding and encapsulation decisions. This allows the distributed switch OS to track Virtual Machines as they migrate and dynamically orchestrate VXLAN overlays without needing software overlays in servers. Since the Switch OS offloads encapsulation/decapsulation for VXLAN to the switch ASIC, there is no performance penalty.
