Embodiment Construction

[0045] Aiming at the above-mentioned problems in the prior art, an embodiment of the present invention provides a technical solution for data transmission, which is applied to an SPB network, and the SPB network includes at least a BEB device and a CE device. In this technical solution, the ACs on each BEB device in the SPB instance are grouped in advance, and the corresponding group forwarding control policy is configured to control the message forwarding between the ACs in the group and the ACs between the groups. And each BEB device is configured with the corresponding relationship between the active group information and the SPB instance and group.

[0046] When the BEB device receives the message sent by the user side, the BEB device determines the AC to which the message belongs, as well as the SPB instance and group to which the AC belongs, and assigns the source group corresponding to the SPB instance and group to the message information; when the BEB device determines...

Abstract

The invention discloses a data transmission method and device. The data transmission method comprises the following steps of: when BEB (Binary Exponential Backoff) equipment receives a message transmitted by a user side, determining an attachment circuit (AC) belonging to the message as well as an SPB (Shortest Path Bridging) case and groups belonging to the AC and allocating source group information corresponding to the SPB case and the groups for the message by the BEB equipment; and when the BEB equipment determines that the received message is required to be locally forwarded in the SPB case, determining to allow the message to be forwarded towards the AC in an egress direction in the SPB case or reject the message to be forwarded towards the AC in an egress direction in the SPB case according to the source group information and a grouping forwarding control strategy by the BEB equipment. According to the data transmission method and device disclosed by the invention, the message forwarding control over the AC in the SPB case is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and device thereof. Background technique [0002] SPB (Shortest Path Bridging, the shortest path bridge) is one of the Ethernet standards defined by IEEE (Institute of Electrical and Electronic Engineers, Institute of Electrical and Electronics Engineers) 802.1aq, and is the MSTP (Multiple Spanning Tree Protocol, Multiple Spanning Tree Protocol) Further extension, aiming to build a large flat non-blocking two-layer network, using SPB-ISIS (Intermediate system to intermediate system, intermediate system to intermediate system) to share the link status in the network, and each node of the network calculates in parallel between each node The shortest path avoids the instability caused by STP (Spanning Tree Protocol) and the low utilization rate of some links. IEEE802.1aq defines two SPB modes: VLAN (Virtual Local Area Network, virtual local area network)...
