Abstract
A system for facilitating efficient multicast traffic management for service discovery is provided. During operation, the system can identify a set of multicast entries associated with a multicast flow in a multicast forwarding data structure of a switch. A respective entry of the data structure can indicate how a corresponding multicast packet is forwarded. If a subset of the multicast entries shares one or more network parameters, the system can compress the subset of the multicast entries based on the shared network parameters to generate a generic entry. The generic entry can then replace the subset of the multicast entries in the data structure. Subsequently, the system can determine a multicast forwarding role of the switch and filter one or more types of multicast control messages based on the multicast forwarding role. Here, the multicast control messages can be directed to the multicast entry.
