## Basic Information
|
||
|
|
|
||
|
|
The **Web Services Dynamic Discovery Protocol (WS-Discovery)** is identified as a protocol designed for the discovery of services within a local network through multicast. It facilitates the interaction between **Target Services** and **Clients**. Target Services are endpoints available for discovery, while Clients are the ones actively searching for these services. Communication is established using **SOAP queries over UDP**, directed to the multicast address **239.255.255.250** and UDP port **3702**.
|
||
|
|
|
||
|
|
Upon joining a network, a Target Service announces its presence by broadcasting a **multicast Hello**. It remains open to receiving **multicast Probes** from Clients that are on the lookout for services by Type, an identifier unique to the endpoint (e.g., **NetworkVideoTransmitter** for an IP camera). In response to a matching Probe, a Target Service may send a **unicast Probe Match**. Similarly, a Target Service could receive a **multicast Resolve** aimed at identifying a service by name, to which it may reply with a **unicast Resolve Match** if it is the intended target. In the event of leaving the network, a Target Service attempts to broadcast a **multicast Bye**, signaling its departure.
