Problems solved by technology

[0008] However, in the prior art, when a group member leaves the group, three protocol message interactions are required. The protocol message has a certain impact on the device, which increases the occupied protocol interaction bandwidth, and the device has certain difficulties in implementing the protocol.

Abstract

The invention provides a member leaving management method and a system based on an IGMPv2 protocol. The method comprises the following steps: S1, a multicast member sending an IGMP leaving group message to an IGMP interrogator router and other multicast members in the multicast group; S2, if other multicast members in the multicast group still need to receive the traffic of the multicast group, sending an IGMP report message to the IGMP inquiry router; otherwise, ignoring the IGMP leaving the group message; S3, after the IGMP interrogator router receives the IGMP leaving group message sent bythe multicast member, If the IGMP report message sent by other multicast members in the multicast group is received, maintaining the multicast member table entry; if the IGMP report message sent by other multicast members in the multicast group is not received, deleting the multicast member table entry. The invention optimizes the IGMP member leaving group mechanism defined in RFC2236, reduces theprotocol message interaction frequency when the IGMP member leaves, saves the impact of the protocol message on the equipment, and effectively simplifies the implementation difficulty of the equipment to the protocol.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a member leaving management method and system based on the IGMPv2 protocol. Background technique [0002] The IGMP (Internet Group Management Protocol) protocol is a multicast member management protocol, which is a multicast protocol in the Internet protocol family. This protocol runs between hosts and multicast routers. There are three versions of the IGMP protocol, namely IGMPv1, v2 and v3. [0003] In the prior art, the method defined in the RFC2236 (Internet Group Management Protocol, Version 2) standard protocol is used to execute the process of leaving a multicast group by a multicast member. [0004] ginseng figure 1 As shown, host 1, host 2 and the IGMP querier router are in the same LAN; host 1 and host 2 have joined the multicast group G (224.1.1.1) by sending IGMP report messages (Report), and IGMP query The router periodically sends the IGMP general q...
