1. Service discovery protocols
UPnP isn't the only solution for easy hardware configuration or, more simply, for discovering services on a network. Other discovery protocols exist, each with its own specific features. The following overview enables us to put UPnP in context, and extract its specific features.
1.1 SLP: Service Location Protocol
SLP is a service discovery protocol developed by the IETF SvrLoc working group since 1999. Its aim is to define a manufacturer-independent standard for TCP/IP networks. It can operate both in a small network, using broadcast for discovery, and in an enterprise network, using service directories. It is one of the few service discovery protocols that can use both modes.
In addition, SLP lets you search for services with Boolean...
