Problems solved by technology

[0013] In order to avoid the out-of-sequence of the above-mentioned strict data frames, the RPR standard requires that when a situation that may cause out-of-order strict data frames occurs, such as protection switching, etc., the strict data frames on the original data transmission path should be completely cleared first, and then start according to the The new data transmission path performs normal data frame sending and receiving processing, but the RPR standard does not give a practical and feasible implementation plan

Embodiment Construction

[0067] The core of the present invention is: when it is determined that the strict data frame in the RPR ring network needs to be cleared, a distributed clearing method is adopted, that is, each node in the RPR ring network determines the strict data to be received and output according to the information carried by the frame. Frame and clear.

[0068] The following further describes the technical solution provided by the present invention based on the core idea of ​​the present invention.

[0069] When the RPR ring network has a link failure or other reasons that cause the ring network topology and link status information to change, and the strict data frame in the ring network needs to be completely cleared, the specific location of the strict data frame transmitted in the ring network is Flexible and diverse, so when the present invention needs to clear the strict data frame in the ring network, each node is used to clear the strict data frame to be received and output, so that ...

Abstract

The present invention provides a method and device for clearing strict data frames in an RPR ring network, the core of which is: determining that the strict data frames in the RPR ring network need to be cleared; Strict data frames received and to be output, and cleared. The present invention adopts the distributed clearing method, utilizes all nodes in the RPR ring network to carry out strict data frame clearing respectively, when the strict data frame needs to be cleared, such as the topology and link state information of the RPR ring network change, the RPR ring network The strict data frame can be completely cleared, thereby avoiding the out-of-sequence phenomenon of the strict data frame, and achieving the purpose of improving the reliability of data transmission in the RPR ring network.

Description

Technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for clearing strict data frames in an RPR ring network. Background technique [0002] RPR ring network technology is a brand-new metropolitan area network technology centered on data formation. The unique SDH (Synchronous Digital Sequence) carrier-class features of RPR technology are effectively combined with the data-oriented high-bandwidth distribution, flexibility and scalability of Ethernet, which can provide operators with data-optimized bandwidth management and cost-effective multiple Business transmission solutions. [0003] The RPR ring network is a reverse dual-ring structure, which can support up to 255 node interconnections. RPR ring network structure and node structure are as attached figure 1 Shown. [0004] in figure 1 Among them, the RPR ring network includes an inner ring and an outer ring. The outer ring is defined as ringlet0 and t...
