Problems solved by technology

[0004] However, when the business is running, although there is a large amount of data exchange in the communication channel between the boards, the device has not reached the state of line-speed forwarding, that is, the line does not perform high-speed, high-load data transmission. Therefore, it cannot be determined In the case of high-speed data transmission, whether there will be errors in the data, so that the reliability of the communication between the boards cannot be accurately detected

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The embodiment of the present invention can be used in a distributed system, and the distributed system includes a main control card, a switching board and at least one service card. Among them, the main control card and the switching board can be set as independent boards in the distributed system, for example: figure 1 In the distributed system shown, alternatively, the switch board can be integrated in the main control card in the form of a switch ch...

Abstract

The invention discloses a method and apparatus for testing communication reliability between cards on the basis of a distributed system, relates to the technical field of communication and can raise the accuracy of communication reliability between cards. The method comprises the following steps: a master card sends commands to other cards through an exchange card; the master card sets a port connecting the exchange card to be in remote loopback and sets the time of the port remote loopback of the master card connected to be exchange card; after the running time of the distributed system reaches the port remote loopback time of each card, the master card gets error data frame statistical information of all the card ports; and the master card determines the reliability of the communication between the cards according to whether the error data frame statistical information is obtained. The invention is suitable for distributed systems.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for testing the reliability of communication between boards based on a distributed system. Background technique [0002] In a distributed system, it generally consists of a main control card, a switching board and various service cards. Among them, the main control card is divided into a single main control card and a dual main control card for master-slave backup, which are used for system management and protocol processing; exchange boards are used for data exchange between boards, and can realize control and protocol data exchange. Switching can also realize the exchange of forwarded data. Usually, the switching board can be integrated in the main control card in the form of a chip, which is invisible to the outside world; the business card is used to realize the data forwarding of different services and achieve parallel processing of different busin...
