Abstract
A method for servicing network traffic in a wide area network (WAN) comprising a plurality of network devices is provided. The method is executed by a network device among the plurality of network devices and comprises: receiving a request to transmit the network traffic to a destination network device where the request specifies that the network traffic is to be serviced by a network service; determining, based on the request and using a service-aware virtual topology (SAVT) routing table, a path through the WAN for reaching the network service and a service instance identifier (ID) of the network service; configuring the network traffic to include a service bit indicating whether service is to be performed and instructions specifying the path for reaching the network service; and transmitting, after configuring the network traffic, the network traffic toward the destination device through the at least one network service.
