Embodiment Construction

[0006] The technology of locating network hosts through routing paths, the specific implementation scheme includes the following steps:

[0007] 1. The source host sends the request, which is characterized in that the source host sends the request to the target host.

[0008] 2. Utilize Tracert order to obtain communication path list, it is characterized in that: at first, Tracert sends a TTL and is 1 IP datagram (every time sending is 3 packets of 40 bytes, including source address, destination address and the time stamp sent ) to the destination, since each router on the path decrements the TTL on the packet by at least 1 before forwarding it, when the TTL on the packet reaches 0, the router should send back an "ICMP has timed out" message In the source system, after the source host receives the return information, it increments the TTL by 1 in each subsequent sending process. When the datagram reaches the destination, the host will not send back the ICMP time exceeded messa...

Abstract

The present invention is a technology for locating the communication path of a network host, and the present invention integrates collection of communication path nodes, data analysis, and output of analysis results as a whole. Its steps comprise as follows: the present invention utilizes Tracert command to determine the path that IP packet arrives target host through, and Tracert command determines the path from a host to other hosts on the network with IP time-to-live (TTL) field and ICMP response packet, This command returns the list of routers that reach the IP address. Each node is the routing IP address that the data packet passes through. Track the route used by the data packet. After collecting the path that can reach the target host multiple times, analyze the relationship between the routes. , construct a communication path topology diagram, display all communication paths from the source host to the target host, and save the data information to the database.

Description

technical field [0001] The invention relates to information collection and analysis technology of a communication network path, in particular to a method for locating and reaching a target host path through a routing path, and belongs to the field of computer application technology. Background technique [0002] At present, international standardization organizations such as the European Telecommunications Standards Institute (ETSI) and the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) all propose that the next-generation telecommunication network is built on an IP or packet switching network. With the continuous development of technology, the technical trend of providing triple play on the IP network is increasingly apparent. However, the original intention of the design of the IP network is only to solve the interconnection problem of devices located in different places, which has great openness. Because of its openness, IP network...
