Embodiment Construction

[0042] The basic principle of the present invention is: on the RPR node, start from this node, and go to the ClassB CIR bandwidth of different destination nodes to allocate respectively; The device obtains the bandwidth allocation requirements of all ClassB CIR services passing through the other nodes or other devices on the ring; performs bandwidth calculation, and accumulates the bandwidth of each ClassB CIR. If the remaining bandwidth is sufficient to meet the new ClassB CIR service requirements, then the bandwidth If the allocation is successful, all ClassB CIR bandwidths can be guaranteed; otherwise, the bandwidth allocation fails, and some ClassB CIR bandwidths cannot be guaranteed.

[0043] In summary, the present invention first calculates the remaining bandwidth on the nodes in the ClassB CIR service transmission path, and when the remaining bandwidth satisfies the new ClassB CIR service development, the service is launched.

[0044] Corresponding to the above princip...

Abstract

The method comprises: deciding if residual bandwidth of the initial node of corresponding ClassB CIR service transmission path and the residual bandwidth of the intermediate nodes located in the transmission path meets the demand of the ClassB CIR service; if both residual bandwidths all meet the newly-added ClassB CIR service demand, the bandwidths satisfying the demand of ClassB CIR service are respectively reserved; bearing the ClassB CIR service on the reserved bandwidth. The invention ensures the ClassB CIR service can be performed on the resilient packet ring.

Description

technical field [0001] The present invention relates to a communication device and a communication method thereof, in particular to an elastic packet data ring and a method for realizing the service thereof. Background technique [0002] In the telecommunications network, the resilient packet data ring (RPR, Resilient Packet Ring) technology has the advantages of intellectualization of IP, economy of Ethernet and high bandwidth efficiency and reliability of optical fiber ring network, and is suitable for broadband IP metropolitan area network networking , is a comprehensive transmission solution for multi-service transmission. The RPR technology can provide carrier-class services at low cost, and reduce transmission costs while providing SDH (Synchronous Digital Hierarchy)-level network reliability. [0003] Referring to FIG. 1 , RPR is a reciprocal double-ring topology, which is composed of multiple nodes (Station) 101 forming a ring loop. Each RPR node 101 uses a 48-bit ...
