			          Abstract 

	     As advances in technology enable us to  implement  very
	high  speed computer networks, we expect to use our networks
	for more  diverse  applications.   While  the  Internet  was
	designed  with  textual data processing in mind, future net-
	works will carry information such as voice,  music,  images,
	and  video,  along with textual data.  Many new applications
	will have real-time performance requirements, where the tim-
	ing of data arrival is crucial to its usefulness.

	     This paper describes a  methodology  developed  at  the
	University  of California at Berkeley to support such appli-
	cations, reviews  related  research  work,  and  proposes  a
	real-time  delivery  system,  composed of a new protocol for
	administration  of  real-time  connections,  combined   with
	modifications  to the Internet Protocol (IP) to support such
	connections.  Transport protocol requirements are also  dis-
	cussed.   This  work  is  intended to facilitate experiments
	with real-time communication over the  Experimental  Univer-
	sity Network (XUNET).
