摘要： In general, techniques are described for enhancing operations of virtual networks. In some examples, a network system includes a plurality of servers interconnected by a switch fabric comprising a plurality of switches interconnected to form a physical network. Each of the servers comprises an operating environment executing one or more virtual machines in communication via one or more virtual networks. The servers comprise a set of virtual routers configured to extend the virtual networks to the operating environments of the virtual machines. A virtual router of the set of virtual routers is configured to prepare tunnel packets by forwarding packets received from virtual machines to an IPSec kernel executing in a host operating network stack, receiving the ESP packets back from the IPSec kernel and forwarding the ESP packets across the virtual networks.

摘要： An example data center system includes server devices hosting data of a first tenant and a second tenant of the data center, network devices of an interconnected topology coupling the server devices including respective service virtual routing and forwarding (VRF) tables, and one or more service devices that communicatively couple the network devices, wherein the service devices include respective service VRF tables for the first set of server devices and the second set of server devices, and wherein the service devices apply services to network traffic flowing between the first set of server devices and the second set of server devices using the first service VRF table and the second service VRF table.
