Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network.

Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate services on a local network. As the name suggests, the actual communication between nodes is done using web services standards, notably SOAP-over-UDP and SOAP-over-IP.

The protocol was originally developed by BEA Systems, Canon, Intel, Microsoft, and WebMethods. It has later been approved as a standard by OASIS (as of July 1st 2009).
