Abstract
Disclosed are systems, methods, and computer-readable storage media for guaranteeing symmetric bi-directional policy based redirect of traffic flows. A first switch connected to a first endpoint can receive a first data packet transmitted by the first endpoint to a second endpoint connected to a second switch. The first switch can enforce an ingress data policy to the first data packet by applying a hashing algorithm to a Source Internet Protocol (SIP) value and a Destination Internet Protocol (DIP) value of the first data packet, resulting in a hash value of the first data packet. The first switch can then route the first data packet to a first service node based on the hash value of the first data packet.
