Techopedia Explains Service Location Protocol

SLP was originally designed for small networks. Later it was expanded for large enterprise network functionality.


SLP uses terminals to broadcast LAN services with required address locator. It requires unrestricted attributes and one or more continuous device recognition scopes – simple group service strings similar to network system neighborhoods.
