TreeNET is a subnet-based topology discovery tool which is built upon the subnet inference tool ExploreNET. Using the inference mechanics provided by ExploreNET, TreeNET refines the measured subnets and tries to infer a whole router - subnet topology on that basis. To reach this goal, it builds a tree-like structure which relies on traceroute measurements conducted to each measured subnet (using Paris traceroute). The tree-like structure (called network tree) aims at highlighting neighborhoods, i.e., network locations bordered by subnets which can reach each other using a TTL value of at most 1 in IP packets. These locations typically consist of a single router or a mesh of several routers, possibly implemented with Layer-2 equipment. The knowledge of the subnets surrounding neighborhoods can be used to perform alias resolution and discover one or several routers and obtain a (near-)complete topology. Indeed, each subnet, if sound, should contain an interface with a particular distance in TTL value which necessarily belongs to the router giving access to that subnet. Listing such interfaces from all subnets bordering a same neighborhood is actually the first step of alias resolution in TreeNET. All TreeNET versions are exclusively available for Linux and for the IPv4 protocol. They are also provided as 32-bit applications, in order to ensure compatibility with all PlanetLab computers.
