Problems solved by technology

[0012] Therefore, in the prior art, when the binding of multicast groups with multicast users among multiple uplink ports of the access device is unbalanced, the multicast service load of each uplink port of the access device may be unbalanced. Equilibrium, which affects the transmission efficiency of access devices
[0013] It can be seen that in the prior art, there is no multicast service implementation method that can avoid the unbalanced multicast service load on the uplink port of the access device

Embodiment 1

[0054] image 3 It is a flow chart of Embodiment 1 applying the solution of the present invention. In this embodiment, the access device has 3 uplink ports, which are respectively uplink port 1, uplink port 2 and uplink port 3, all of which are available uplink ports; the access device Connect 10 multicast users, namely multicast user 1 to multicast user 10; the relative values ​​of the preset loads of the three uplink ports are 3, 2 and 1 respectively, that is, the load ratio between the uplink ports is uplink port 1 : Uplink port 2: Uplink port 3 = 3: 2: 1, the preset values ​​of the three uplink ports are 3, 2, 1 respectively; the multicast source can provide users with 6 multicast groups in total, which are multicast groups A to multicast group F. In this embodiment, user 1 to user 3 are multicast members of multicast group A, and the multicast data of multicast group A is input from the uplink port 1 of the access device; user 4 and user 5 are multicast group B The mult...

Embodiment 2

[0065] Figure 4 It is the flow chart of Embodiment 2 of applying the solution of the present invention. In this embodiment, the access device has 3 uplink ports, which are respectively uplink port 1, uplink port 2 and uplink port 3, all of which are available uplink ports; the access device connects There are 10 users, namely user 1 to user 10; the relative values ​​of loads borne by the 3 uplink ports are 3, 2 and 1 respectively; the multicast source can provide a total of 6 multicast programs, that is, there can be 6 multicast groups, They are multicast group A to multicast group F respectively. In this embodiment, user 1 to user 3 are multicast members of multicast group A, and the multicast data of multicast group A is input from the uplink port 1 of the access device; user 4 and user 5 are members of multicast group B Multicast members, and the multicast data of multicast group B is input from the uplink port 1 of the access device; users 6 to 8 are multicast members of...

Abstract

When asking for joining a multicast group, user sends report message in Internet group management protocol (IGMP) of the multicast group to access equipment; based on value of actual load of each available up going port, and load value setup in advance, the access equipment determines a up going port going to transfer multicast data of the multicast group; and through the determined up going port, the received report message in IGMP is sent to multicast route; after multicast route receiving the report message in IGMP from the access equipment, multicast route sends the multicast data of the multicast group through the determined up going port in the access equipment to the access equipment; then, the access equipment sends the multicast data to the user. The invention avoids unbalanced load of multicast service carried by up going port in access equipment so as to raise transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of IP multicast, in particular to a method for realizing multicast service. Background technique [0002] IP multicast refers to sending data packets to a certain subset of nodes in the network in the IP network, and this subset is called a multicast group. The basic idea of ​​IP multicast is that the source host only sends one copy of multicast data, the destination address in this multicast data is the multicast group address, and all multicast users in the multicast group can receive the same data copy. Using the multicast feature of the network, operators can conveniently provide some new value-added services, including Internet information service fields such as online live broadcast, Internet TV, distance education, telemedicine, Internet radio, and real-time video conferencing. [0003] Generally speaking, to realize the multicast service, the devices in the network need to support the Internet Group...
