Abstract
In one embodiment a method includes detecting, at a first Wide Area Network (WAN) device deployed at an edge of a WAN, a packet passing through the first WAN device and departing a node with which the first WAN device is associated for another node connected to the WAN, identifying, by the first WAN device, a network destination address to which the packet is addressed, obtaining from memory accessible to the first WAN device an identifier of another WAN device associated with the network destination address, and marking the packet with the identifier to generate a marked packet. The marked packet is then received by a WAN device, which detects the identifier, and passes the marked packet to the identified WAN device. In an embodiment, the WAN device associated with the network destination address is a WAN device that first detects a synchronization-acknowledgement (SYN-ACK) packet.
