Abstract: Virtual network controllers are described that automatically generate policies and configuration data for routing traffic through physical network function (PNF) service chains in a multi-tenant data center. An example network controller includes a memory and processing circuitry configured to: automatically generate, for one or more integrated routing and bridging (IRB) units of corresponding virtual network forwarding tables of a switch of a switch fabric of a data center network, configuration information that, when deployed, causes the IRB units to direct data traffic conforming to multiple communication protocols and flowing over a plurality of virtual networks between a first set of server devices and a second set of server devices positioned outside of the switch fabric (i) toward a service device logically positioned outside of the switch fabric and coupled to the switch, and (ii) back from the service device into the switch fabric via the switch.

Abstract: A first device may receive first route information, from a second device, identifying a first route to the second device for a packet to be provided toward a destination via the second device. The first device may generate second route information identifying a second route to the first device for the packet. The first device may provide the second route information to a third device. The packet is to be received by the first device. The first device may receive the packet from the third device via the second route after providing the second route information to the third device. The packet is to be provided to the second device by the first device. The first device may perform a service on the packet based on being identified by the second route information as a next hop for the packet and prior to providing the packet to the second device.
