The Service Location Protocol provides mechanisms whereby service agent
clients can advertise and user agent clients can query for services.
The design is very much demand-driven, so that user agents only obtain
service information when they specifically ask for it. There exists
another class of user agent applications, however, that requires
notification when a new service appears or disappears and update when
the attributes of the service change. In the RFC 2608 design, these
applications are forced to poll the network to catch changes. In this
document, we describe a protocol for allowing such clients to be
notified when a change occurs, removing the need for polling.

In the body type:

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
		
		
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
