摘要： In some cases, an IPTV client may send multiple IGMP Report/Join requests to an IPTV gateway, primarily due to a system or software failure. This may flood the IPTV client device with unwanted streaming data. A method and an apparatus for managing Internet Group Management Protocol (IGMP) multicast groups of IPTV service are suggested. The method comprises receiving a request from an IPTV client device for joining a new IGMP multicast group of IPTV service; and adjusting IGMP multicast groups of the IPTV client device according to a preset rule as a function of the number of the IGMP multicast groups which are joined by the IPTV client device over a preset value. According to the disclosure, only a preset number of IGMP groups are allowed for an IPTV client device, which can reduce the risk of streaming data flooding the system.

摘要： A method and an apparatus for communication between a first network device and second network device are suggested. The method comprises, at the level of the first network device: receiving, from the second network device, one or more requests for SNMP Set operation; caching the one or more requests; and upon a determined time period being reached, processing the cached one or more requests. A cache mechanism is suggested so that an SNMP agent can cache the requests for SNMP Set operation for a time period and process these requests in batch.
