Communication protocol online diagnosis method and diagnosis system

Abstract

The invention relates to a communication protocol online diagnosis method, which comprises the following steps: step 1, using format information of a message in an XML description protocol as an interface file for protocol diagnosis; and step 2, creating a protocol process assessment XML document, namely completing an online diagnosis function of the application layer communication protocol according to the information configured by the diagnosis interface, identifying a message field, giving explanation information of each field of the message, and meanwhile, carrying out protocol process diagnosis to give a diagnosis result. Compared with the prior art, the format definition and the protocol process diagnosis information of the message are described by using the XML language of the general standard, so that the protocol diagnosis process and result can be configured, and the method is suitable for various application layer protocols, can effectively adapt to the situations of adding,expanding and modifying protocols, and enables the protocol diagnosis process to be simpler and more efficient, and the like.

Description

technical field [0001] The invention relates to the communication field, in particular to an online diagnosis method and a diagnosis system of a communication protocol. Background technique [0002] The communication protocol is the rules and standards formulated for data exchange between network devices, and it is a medium for information exchange between communication parties to achieve state and control synchronization. The communication protocol usually has two parts, one is the standard protocol, such as the TCP / IP protocol, which is usually formulated by an international standard organization or an industry standard organization, and is a standard that all communication devices must follow. The second is the application layer protocol, which is the rules for data interaction between applications. For the underlying standard protocol, it is already very reliable and does not require too much attention, but for the application layer protocol, it often needs continuous d...

Problems solved by technology

However, in the real world, there are many and complex application layer protocols, and there are many custom protocols. If the diagnosis of each protocol is implemented through program development, not only the workload is huge, but also a specific programming language is required.
