Abstract

The invention relates to a multicast service data flow load balancing method in the field of data communication. Aiming at the problem of unbalanced load caused by multicast service data flow in transmission process in the prior art, the invention discloses a transmission control method with balanced multicast service data load and an access device thereof. The method comprises the following steps: a. receiving a multicast adding request, and identifying the multicast information of the multicast adding request; b. distributing the multicast data flow of different multicast groups into different VLANs for transmission according to the multicast group information; and c. forming a forwarding list item of the request multicast in the distributed VLANs, and forwarding the multicast adding request to control protocol message. The access device comprises a receiving module of the multicast adding request, a VLAN distribution module, a multicast forwarding table maintenance module, and a multicast service data forwarding module. The invention can realize load balancing in multi-instance networking environment and makes full use of network bandwidth resources.

Description

technical field [0001] The invention relates to a load balancing method for multicast service data streams in the data communication field, in particular to a load balancing control and data forwarding method for multicast data streams in a two-layer Ethernet environment. Background technique [0002] In the carrier or enterprise network environment, in order to improve the reliability of the Layer 2 Ethernet network, dual-homing or ring networking is usually selected. The same device is connected to more than one device through two redundant links, so that when a link occurs Or when the equipment fails, the service can be quickly switched to avoid long-term network interruption. For the network structure, see figure 1 and figure 2 (In different networking modes, network devices have different names). The multicast data stream forwarding process is as follows: The multicast service data stream is initiated by the multicast source, passes through the Layer 3 forwarding dev...
