Problems solved by technology
Second: The data packets received on the tunnel can only be broadcast to the local
Third: does not support tunnel translation, that is, data packets are forwarded from one tunnel to another
It can be seen that according to the existing data packet forwarding method, two broadcast tables need to be applied for to maintain the broadcast members of the broadcast group. Although the network closed loop can be avoided on the basis of following the broadcast principle, using this method to maintain two broadcast tables forwarding method, the means adopted to realize the forwarding of data packets are complex, and waste network bandwidth resources

Embodiment Construction
[0025] The basic idea of the present invention is: complete the distinction of port attributes in the forwarding module, avoid forwarding the data message whose entry attribute information is the same as the exit attribute information of the exit module to the exit module, and adopt the present invention to avoid the problem of network closed loop , which saves bandwidth resources and is simple and easy to implement.
[0026] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.
[0027] Such as figure 2 As shown, a system for realizing data packet forwarding includes: an entry module 1, a forwarding module 2, and an exit module 3, and the entry module 1, the forwarding module 2, and the exit module 3 are all located in PEs. Wherein, the entry module 1 is used to receive the data message carrying the entry attribute information and send it to the forwarding module 2 . The forwarding module 2 i...

The invention discloses a system for realizing data message forwarding, which comprises an entry module, a forwarding module and an exit module, wherein the forwarding module is used for receiving and analyzing entry attribute information in data messages, comparing the entry attribute information with exit attribute information, discarding the data messages of which the entry attribute information is the same as the exit attribute information, and forwarding the data messages of which the entry attribute information is different from the exit attribute information into the exit module. Theinvention also discloses a method for realizing the data message forwarding, which comprises the following steps: in the forwarding module, the distinguishing of port attributes of the data messages is realized, the entry attribute information with the exit attribute information are compared, the data messages of which the entry attribute information is the same as the exit attribute information are discarded, and the data messages of which the entry attribute information is different from the exit attribute information are forwarded. The adoption of the system and the method can realize the fast forwarding of the data message, avoid the loop closing of a network, and save the bandwidth resource of the network.
Description
technical field [0001] The invention relates to data message forwarding technology, in particular to a system and method for distributed network equipment to implement data message forwarding in a multi-point-to-multipoint network by adopting provider backbone transmission technology (PBT). Background technique [0002] With the further requirements of enterprise users for bandwidth and business service quality and price ratio, operators' demand for carrier-grade Ethernet equipment is growing rapidly, and PBT technology emerges as the times require. PBT technology is committed to applying Ethernet technology directly to Ethernet Transmission of business. PBT technology is based on MAC stacking (Mac-in-Mac), that is, 802.1ah standard carrier backbone bridging (PBB) technology and a series of related standards. The core of PBT technology is to configure through network management and The Ethernet business in Ethernet (CE) has connectivity in fact, so as to realize the functio...
