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...
Embodiment 2
[0037] An Internet layer connection measurement method using Internet group management protocol messages and its topology, determining an AS network of an autonomous system as the measurement range IP_blocks, expressing each IP address block in the autonomous system in the form of a network prefix or an IP address range : 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 select from these IP paths Part or all of the intermediate hops, and the global IP addresses of the intermediate hops within the measurement range IP_blocks, 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 can also be used to form the next round of IP addresses Measurement target address set Set_of...
Embodiment 3
[0040] An Internet layer connection measurement method and its topology using Internet group management protocol messages determine that the Internet is the measurement range IP_blocks, expressed in the form of IP address ranges or network prefixes: select a group of router interface Internet from the measurement range IP_blocks The protocol IP address is used as the measurement target address set Set_of_dest; during periodic measurement, the IP address of the router interface obtained from the previous round of measurement is used to form the next round of measurement target address set Set_of_dest;
[0041] Other steps are the same as in Example 1.
