Abstract: An example network device includes a network interface and a control unit that receives a packet having header information. The control unit includes a forwarding structure having a plurality of entries that each refers to one of a plurality of logical interfaces, a forwarding engine configured to access the forwarding structure to select a first logical interface to which to forward the packet based on the header information, wherein the first logical interface comprises a pseudo-device interface (PDI). The control unit also includes a PDI module that tunnels the packet to an external service complex (ESC) by at least applying a set of metadata to the packet, encapsulating the packet with a header, and forwarding the packet to the ESC via the network interface, and wherein the metadata allows the ESC to determine a set of services to be applied to the packet based on the metadata.

Abstract: A network device may receive network traffic from a first device. The network device may identify, based on the network traffic and a service level agreement, stored by the network device, that a service is to be applied to the network traffic. The network device may send the network traffic to a second device, the second device using a service plane to apply the service to the network traffic. The network device may receive the network traffic from the second device, the network traffic having the service applied by the second device; and send the network traffic, having the service applied by the second device, to a third device.
