Method for locating embedded control path fault

Abstract

The invention discloses a method for positioning the faults of an embedding control path, which comprises the following steps that: a part with the highest packet loss rate is determined, a splitter is added on a cable between each two network elements, a receiving port of a reference network element which is determined to have no faults is connected, all the network elements and the receiving and sending packet values of a counter of the receiving and sending packets of a main control board of the reference network element which are corresponding to all the data paths in a link are taken as the original values; the both ends of the link are connected with data instruments with the functions of the receiving and sending packets for carrying out the two-way receiving and sending packets; a period of time of the receiving and sending packets is recorded, the receiving and sending packet values of all the data paths which are recorded by all the network elements and the main control board of the reference network element of the link are compared with the corresponding original values; and the faults of the embedding control path are positioned according to the comparison result. As the method adopts the main control board to record the number of the data packets which are generated in the packet sending process, the reference direction is connected by the splitter for comparing the number of the data packets of all the directions, thus improving the ECC fault positioning efficiency.

Description

technical field [0001] The present invention relates to a fault location method of an SDH network (Synchronous Digital Hierarchy), in particular to a fault location method of an ECC (Embedded Control Channel) fault, which is especially suitable for adopting a star structure and is a The main control board and the connecting board (optical board or tributary board) realize the hardware forwarding through the ECC bus and complete the SDH network fault location method of the ECC routing function. Background technique [0002] The powerful and flexible networking capabilities of SDH will inevitably lead to complex network structures. The DCC (Digital Control Channel, Digital Control Channel) / ECC protocol forwarding technology as the network management information channel naturally becomes the most complex and core in the SDH network management system. Technology. Among the various existing DCC / ECC forwarding technologies, the star structure is adopted, and the main control boar...

Problems solved by technology

[0005] In the process of locating ECC faults, the most difficult thing is to determine the specific environment and application method that triggers the fault, especially when there is a problem with the cooperation between the boards in a network element, it is even more difficult to find out which part is defective

Although the single board software and logic can be judged by means such as setting variables and monitoring related registers during the implementation process, in some cases where resources are tight and conditions are complicated, it is not possible to obtain enough control points and monitoring points for precise positioning.

[0006] In a star bus system, for ECC, a function that requires many parts to work together, when a problem occurs, because the relevant parts are in charge of different developers, if no effective testing method can be found to assist Positioning, and it will be difficult for the developers to find the part they are responsible for, and it will be difficult to find the cause of the problem, which will have a great impact on the development progress of the product
