Example Embodiment

[0023] Example 1

[0024] Such as figure 2 As shown, in the method for implementing multicast stream forwarding in Embodiment 1 of the present invention, each routing bridge (RB) forwards the received uplink or downlink multicast stream according to the distribution information of the multicast tree. Among the distribution information of the multicast tree, The multicast tree is allocated according to the upstream direction and the downstream direction respectively. Specifically, the method includes:

[0025] Step 201: The routing bridge (RB) obtains and stores the allocation information of the multicast tree of the routing bridge group (RBv), and the multicast tree in the allocation information of the multicast tree is allocated according to the uplink direction and the downlink direction respectively ;

[0026] The distribution information of the multicast tree may be specifically generated in a configuration manner or obtained by each routing bridge based on the same distributio...

[0036] Example 2

[0037] Such as image 3 As shown, in the method for implementing multicast stream forwarding in Embodiment 2 of the present invention, each routing bridge (RB) forwards the received uplink or downlink multicast stream according to the distribution information of the multicast tree. Among the distribution information of the multicast tree, The multicast tree is allocated according to the upstream direction and the downstream direction respectively, and specifically includes:

[0038] Step 301: The routing bridge (RB) obtains and stores the allocation information of the multicast tree of the routing bridge group (RBv), and the multicast tree in the allocation information of the multicast tree is allocated according to the uplink direction and the downlink direction respectively , And the multicast tree is allocated in each link aggregation group (LAG) or local area network (Local Area Network, LAN) in the downlink direction;

[0039] For example, if there are 6 mult...

Example Embodiment

[0050] Example 3

[0051] Embodiment 3 of the present invention focuses on the forwarding of multicast streams in the downstream direction. Each routing bridge (RB) forwards the received upstream or downstream multicast streams according to the distribution information of the multicast tree. The multicast tree is allocated according to the upstream direction and the downstream direction, specifically, such as Figure 4 As shown, the method for implementing multicast stream forwarding includes:

[0052] Step 401: The routing bridge (RB) obtains and stores the distribution information of the multicast tree of the routing bridge group (RBv) in the downlink direction, and the multicast tree is in each link aggregation group (LAG) or local area network in the downlink direction. (LAN) internal distribution, a routing bridge (RB) distributed in the downstream direction of a multicast tree includes a primary forwarding device and a backup forwarding device;

[0053] The distribution inform...

Abstract

The invention relates to a multicast flow forwarding implementation method and a routing bridge (RB). Each RB forwards a received uplink or downlink multicast flow according to the distribution information of a multicast tree; and the multicast trees in the distribution information of the multicast trees are respectively distributed according to an uplink direction and a downlink direction. When the downlink direction fails, multicast flow forwarding in the uplink direction cannot be influenced.

Description

technical field [0001] The invention relates to network communication technology, more specifically, a multicast flow forwarding realization method and a routing bridge (RB). Background technique [0002] TRILL is the English abbreviation of Transparent Interconnection over Lots of Links, which is used to solve the multipath (or L2MP (Layer 2 Multiple Path)) problem in the large Layer 2 network of the data center. The L2MP is realized by introducing the IS-IS (Intermediate System to Intermediate System, Intermediate System to Intermediate System) routing protocol into the Layer 2 network. In a TRILL network, a device running the TRILL protocol is called an RBridge (routing bridge, also referred to as "RB" hereinafter), and a Nickname (alias) uniquely identifies an RBridge. At the entrance of the TRILL network, it is responsible for encapsulating the original data frame of the end device (End Station) into TRILL format (that is, adding a TRILL header and an external frame he...
