Method for effectively measuring and constructing IPv6 network topology

Abstract

The invention provides a method for effectively measuring and constructing an IPv6 (Internet Protocol Version 6) network in order to solve the problem that the network topology cannot be measured by using a Trace tool due to the sparse number of seed addresses in the IPv6 network. The is characterized by comprising the following steps: filtering out an initial seed address set from an open Internet topology measurement data set; and expanding the initial seed address set into an updated address set, performing survival detection on the updated address set to obtain an active address set, and measuring the active address set by adopting a Traceroute method and constructing the topology of the target IPv6 network. The method has the advantages of being capable of effectively measuring the IPv6 network topology and high in robustness.

Description

technical field [0001] The invention belongs to the field of network communication, in particular to a method for effectively measuring and constructing IPv6 network topology. Background technique [0002] In response to the rapid development of the Internet in human society, an IPv6 protocol with a 128-bit address has been widely used. As we all know, network topology is the basis of many network technologies such as network performance management, fault management, and security management. However, due to considerations of business competition, technical level, and security, network service operators usually keep their network topology secret. It is usually necessary to analyze and judge through the method of network measurement, and infer the topology of a certain network. Therefore, it is very necessary to construct the topology of the IPv6 network by means of measurement. At the same time, because the IPv6 network has a much larger address space than the IPv4 network, ...

Problems solved by technology

[0006] Aiming at the current situation that the IPv6 network address space is huge but the number of active addresses is small, and the network measurement tool Traceroute cannot be used to measure the IPv6 network topology, the present invention proposes an effective method for IPv6 network topology measurement in the case of few seed addresses

[0008] The present invention aims at the problem that the current IPv6 network cannot perform network topology measurement due to the scarcity of seed addresses, and proposes an effective method for measuring the IPv6 network topology
