Problems solved by technology

However, for the multicast packets copied on the ingress service disk, all the multicast packets are copied at one time, occupying the bandwidth of the ingress service disk, resulting in low forwarding efficiency from the ingress service disk to the line disk; in addition, it will also affect the ingress business Disk unicast traffic affects the forwarding capability of single disk unicast packets

Embodiment 1

[0035] A multicast packet with a multicast ID of 1002 enters ingress disk A and is forwarded by ingress disk A to cross-connect disk B. According to the configuration in the multicast configuration table, the cross-connection disk B finds that the multicast packets need to be forwarded to the egress disks C1, C2, and C3, and then copies the multicast packets. The number of copies is 3, and the copied multicast The packets are forwarded to the egress disks C1, C2, and C3 respectively.

[0036] The egress disk C1 obtains the ports C1P1 and C1P3 that need to be forwarded according to the configuration of the multicast membership table, and copies the received duplicate multicast packets again to form a secondary replicated multicast packet. The number of secondary replicated multicast packets There are 2 copies, which are forwarded through ports C1P1 and C1P3 respectively.

[0037] The egress disk C2 obtains the port C2P2 that needs to be forwarded according to the configuration...

Embodiment 2

[0040] The multicast packet with the multicast ID 1006 enters ingress disk A and is forwarded by ingress disk A to cross-connect disk B. According to the configuration in the multicast configuration table, the cross-connect disk B finds that the multicast packets need to be forwarded to the egress disks C1 and C2, and then copies the multicast packets. The number of copies is 2, and the copied multicast packets They are forwarded to the export disks C1 and C2 respectively.

[0041] The egress disk C1 obtains the ports C1P1 and C1P2 that need to be forwarded according to the configuration of the multicast membership table, and copies the received multicast packets again to form a secondary multicast packet. The number of multicast packets to be copied twice There are 2 copies, which are forwarded through ports C1P1 and C1P2 respectively.

[0042] The egress disk C2 obtains the port C2P1 that needs to be forwarded according to the configuration of the multicast membership table...

Abstract

A high-efficiency multicast implementation system and method in transmission equipment, relating to the field of data transmission, the system includes an entry disk, a cross disk and at least one exit disk, each exit disk has at least one port, and the cross disk is provided with a multicast configuration The table is used to configure the corresponding relationship between the multicast group and the export disk; each export disk has a multicast member table, which is used to configure the corresponding relationship between the multicast group and the ports in the export disk. Multicast packets are forwarded from the ingress disk to the cross-connect disk. The cross-connect disk copies the multicast packet according to the multicast configuration table and forwards it to the corresponding egress disk. Each corresponding egress disk The broadcast message is copied again and forwarded through the corresponding port. The invention effectively controls the bandwidth occupied by the multicast message, improves the forwarding efficiency of the transmission equipment, and ensures the performance of the transmission equipment.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to an efficient multicast realization system and method in transmission equipment. Background technique [0002] The network IP trend is the biggest trend in the network development of telecom operators in recent years. Driven by this trend, the IP process of the mobile network is also gradually unfolding. As an important part of the mobile network, the IP of the mobile bearer network Transformation is a very important content. [0003] The IPRAN (IP Radio Access Network, IP-based wireless access network) solution can provide higher bandwidth resources to meet the explosive growth of data in the future; it has good maintainability and scalability; rich three-layer functions provide higher Transmission efficiency, supporting integrated service bearer and seamless evolution to LTE (Long Term Evolution, long-term evolution of universal mobile communication technology); plug-and-play f...
