A gateway proxy saves each listener for every specific multicast group, thus the gateway knows if a listener is the last one in the group when it receives a leave report from a listener. The gateway leaves the group immediately without sending specific query if the leave report comes from the last listener of the current group, thereby significantly reducing the leave latency. Otherwise, the standard procedure wins, and the gateway sends out a specific query when the leave report is not from the last listener."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stateful IGMP fastleave","description":"Methods, systems, and computer readable media described herein can be operable to facilitate an IGMP fastleave using a listener reference count.
