Problems solved by technology

However, in the prior art, there is no diagnostic method specifically for application-layer routing, which cannot provide timely and effective routing information for diagnosing the transmission of the application message, which is not conducive to discovering network configuration problems and domain security issues in the transmission of the application message
In addition, these AVP information cannot provide enough information for routing diagnosis

Embodiment 3

[0060] The diagnosis message in the third embodiment is a complete message flow matched with a specific application. The diagnosis message is initiated from Diameter node A, that is, the Diameter protocol client, and passes through multiple nodes (possibly through multiple domains), and finally the diagnosis message reaches server k, and server k returns a response message of the diagnosis message with a success value. Through such a diagnosis process, it is possible to collect and establish the current Diameter application message routing path, each participating Diameter node on the path, each Diameter node role, and the time when the Diameter application message arrives at each Diameter node. By running its own diagnostic function multiple times, it can also diagnose which specific applications are supported by each participating Diameter node on the path, whether these applications are fully deployed, what is the current status of Diameter nodes, and what is the current net...

Abstract

The invention relates to a method, a system and device for diagnosing network routing based on a diameter protocol. The method includes the steps as following: a source Diameter node constructs a diagnosis message according to a diagnosis parameter, then the diagnosis message is transmitted, a middle Diameter node receives the diagnosis message and adds in self-diagnosis information to the diagnosis message and then the diagnosis message is still forwarded, until the diagnosis message is arrived to a Diameter protocol server for processing the diagnosis message and a diameter node which can not forward the diagnosis message; the Diameter protocol server for processing the diagnosis message or the diameter node which can not forward the diagnosis message constructs a response message for the diagnosis message, and the self-diagnosis information, and information and a response category in the diagnosis and are carried and transmitted, the middle Diameter node received the response message and adds in the self-diagnosis information to the response message and then the response message is still forwarded, until the response message is arrived to the resource Diameter node, and the resource Diameter node resolves the response message and obtains related routing information.

Description

technical field [0001] The invention relates to routing diagnosis technology in communication network, in particular to a method, device and system for routing diagnosis in a network based on Diameter protocol. Background technique [0002] In an Internet Protocol (IP, Internet Protocol) network, it is often necessary to diagnose the route through which the IP message passes, such as determining whether the route through which the IP message is transmitted is unblocked and the network device it passes through. At present, in the IP network, there are two methods for routing diagnosis: one is a packet Internet probe (ping) routing diagnosis method; the other is a route tracing (traceroute) routing diagnosis method. These two methods are briefly introduced below. [0003] Ping routing diagnosis method [0004] The method adopts Internet Control Message Protocol (ICMP, Internet Control Message Protocol) to send back messages and responses thereof, and is often used in IP netw...
