Problems solved by technology

[0004] In addition, when the existing measurement methods based on the traceroute mechanism generate router-level topology maps, they are mainly based on UDP packets for alias detection, or methods that combine IP packet identifier IP_ID and measurement paths for analysis, and the obtained alias information is incomplete or Inaccurate, thus affecting the accuracy of the Internet layer router-level topology map

Embodiment 1

[0029] An Internet layer connection measurement method using Internet group management protocol messages and related topologies, determine the network of an Internet service provider ISP as the measurement range IP_blocks, and represent each block owned by the ISP in the form of a network prefix or an IP address range. IP address block: Randomly select a group of target addresses from each stub network in the measurement range IP_blocks, and then use the IP path measurement method of the traceroute mechanism to measure the selected target addresses to obtain a set of IP paths, and then obtain a set of IP paths from these IP Select part or all of the global IP addresses of the intermediate hops in the path, and the intermediate hops are within the measurement range IP_blocks to form the measurement target address set Set_of_dest; in periodic measurement, the IP address of the router interface obtained in the previous round of measurement is used to form the next round The measur...

Abstract

The invention relates to an Internet layer connection measuring method adopting an IGMP (Internet Group Management Protocol) message and a relevant topology. The detection message of the prior art is easy to be identified as an aggressive behaviour and then is filtered, which breaks the integrity of measurement topology. The method comprises the following steps of: determining a measurement range represented by a group of Internet protocol IP address blocks and selecting the IP addresses of a group of router interfaces as a measurement goal address set from the measurement range; filling the IP detection message for packaging an IGMP neighbor request type message, and then sending the detection message; processing a response message according to the type of the response message if the response message is received in a preset time; and implementing waiting time overtime processing if the response message is not received in the preset time. An IP-stage or router-stage network topological graph can be constructed according to IP connection information and alias information which are obtained by measurement. The invention is used for a measuring method of moderate resistance filtration in an IP network.

Description

Technical field: [0001] The invention relates to an Internet layer connection measurement method using an Internet group management protocol message and related IP-level topology and router-level topology. Background technique: [0002] The traditional method of measuring Internet Protocol IP connection and network topology mainly adopts the measurement method of traceroute mechanism. First, a detection message with TTL=1 is sent from the measurement source point S to a certain measurement target D, and the returned ICMP timeout message is received. , or wait for a predetermined time t 0 (for example, 5 seconds), then send a message with TTL=2, and so on, until a message indicating that the target is reached is received from the detection target, or the TTL increases to a predetermined threshold (for example, 30). At this point, the path detection process for the measurement target D ends. According to the source IP addresses contained in the returned packets in turn, the ...
