Abstract
A controller implemented on computing equipment may be used to control switches in a network. End hosts and service devices may be coupled to the switches in the network. The controller may generate a virtual network topology of virtual switches and virtual routers. The controller may control the virtual routers and/or virtual switches to perform service insertion. The controller may perform service insertion by controlling the virtual routers and/or virtual switches to redirect network traffic through one or more selected service devices. The controller may determine which network traffic is to be redirected to which service devices based on a service insertion policy that identifies network traffic and services to be performed on the network traffic.
