Abstract: Techniques for routing data packets through service chains within and between public cloud networks of multi-cloud fabrics. A router in a network, e.g., a public cloud network, receives data packets from nodes in the network through segments of the network. Based at least in part on (i) a source address of the data packet, (ii) a destination address of the data packet, and (iii) an identity of the segments of the network from which the data packets are received, the router determines a next node in the network to which the data packet is to be forwarded. The router may then forward the data packet through another segment of the network to the next node and then receive the data packet from the next node through the another segment.
