Embodiment Construction

[0026] Below, refer to the attached Figure 1-5 The time management-based controllable multicast realization method and device of the present invention are described in detail.

[0027] Such as figure 1 Shown is a schematic diagram of the multicast network structure of the present invention. The controllable multicast device based on time management of the present invention includes a message parsing unit and a list storage unit, wherein the list storage unit is used to store the multicast entry management table GROUP_LIST and the multicast entry time management table GROUP_TIME_LIST; The parsing unit is used to receive the Internet multicast member management protocol report IGMP REPORT message sent by the multicast user, and query the GROUP_LIST whether there is a multicast entry specified in the IGMP REPORT message, and when the multicast entry does not exist , check whether the current time is in the period and / or time period set in GROUP_TIME_LIST, and create the multic...

Abstract

The invention provides a method and a device for realizing controllable multicast based on time management, wherein the method comprises the following steps of: receiving an IGMP REPORT (Internet Group Membership Protocol REPORT) message transmitted from a multicasting user through a multicasting device, checking whether the current time is in a set period section and / or time section set in a group time list or not when a multicasting list appointed in the IGMP REPORT message does not exist in the group list and creating the multicasting list if the result is positive, or canceling the IGMP REPORT message. The invention can provide individual multicasting services for different users according to individual requirements on users and better promotes the satisfaction degree of the users.

Description

technical field [0001] The invention relates to multicast technology, in particular to a controllable multicast realization method and device based on time management. Background technique [0002] Existing multicast technology mainly manages the creation and deletion of multicast entries, and the joining and leaving of multicast users by running the Internet Group Management Protocol (IGMP) on layer 2 and layer 3 network devices. And use this to control whether the multicast user can obtain the corresponding multicast data stream from the multicast source or the multicast router. [0003] In a multicast network, a Layer 2 multicast device maintains a multicast table to implement the IGMP SNOOPING protocol. We call this table the multicast entry management table GROUP_LIST. By adding or deleting entries in GROUP_LIST, you can create or delete corresponding multicast entries; by adding or deleting member ports in each entry, you can manage the joining and leaving of users of...
