Multimedia data transport over ad hoc networks is a challenging
problem. The dynamic nature of the underlying routing and the highly
varying quality of the wireless communication links present
additional hurdles for the transport of real-time traffic between
hosts. However, the mesh topology of ad hoc networks implies the
existence of multiple paths between any two nodes. It has been shown
in the literature that path diversity provides an effective means of
combating transmission errors and topology changes that are typical
in ad hoc networks. Moreover, data partitioning techniques, such as
striping and thinning, have been demonstrated to improve the queuing
performance of real-time data. Recognizing the advantages of these
techniques, as well as the increasing need for video services in ad
hoc networks, we propose a new transport protocol to support
multipath transport of real-time data. The new protocol, called
Multi-flow Real-time Transport Protocol (MRTP), provides a convenient
vehicle for real-time multimedia applications to partition and to
transmit data using multiple flows. Even though the basic idea of
MRTP is presented in the context of ad hoc networks, the benefits
demonstrated by the use of MRTP is equally applicable to other types
of IP network providing multi-media streaming services including the
Internet.

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
