Abstract: Techniques are described for facilitating flow symmetry using a scalable service platform that anchors the service chain. The scalable service platform may facilitate flow symmetry and, at least in some cases, flow stickiness for a first packet flow (a “forward packet flow”) and a second, related packet flow (a “reverse packet flow”) both traversing the service chain in the forward and reverse directions, respectively. For example, a virtualized computing infrastructure may deploy a scalable service platform to perform load balancing of multiple forward packet flows, received from the gateway, among multiple parallel service instances for an ingress service in a service chain. For each corresponding reverse packet flows for the multiple forward packet flows, the scalable service platform load balances the reverse packet flow to the service instance for the egress service in the service chain that is applied to the corresponding forward packet flow.

Abstract: The technology disclosed herein enables multicast network traffic to pass an RPF check in a logical router having separated packet handlers. In a particular embodiment, a method includes, in a north/south packet handler of a first logical router, receiving first network traffic from an east/west packet handler of the logical router. The first network traffic is multicast network traffic and the logical router is a first hop router for the first network traffic from a source of the first network traffic. The method further includes identifying an entry for the source in unicast routing information for unicast network traffic. Identifying the entry indicates that the first network traffic passes a reverse path forwarding (RPF) check. In response to the first network traffic passing the RPF check, the method includes transferring the first network traffic from the north/south packet handler to a next hop for the first network traffic indicated by first multicast routing information.
