Abstract
This specification describes how the Link Layer Topology Discovery (LLTD) protocol operates
over wired (802.3 Ethernet) and wireless (802.11) media. As the protocol name suggests, the
core functions of LLTD enable applications to discover the topology of a network. In addition,
LLTD has optional QoS Extensions that applications can use to diagnose problems, especially
those involving signal strength on wireless networks or bandwidth constraints in home networks.
LLTD is a key component of the Microsoft® Windows® Rally™ set of technologies.
