may be multiplexed on the same path (page 1362). In the video-
phone connection, the conversation may continue on the audio
channel even if the video channel fails (page 1363, column 2).
Sometimes, a quality degradation on a channel may affect the
other channels. In a high fidelity stereo, a sustained data loss
in one audio channel may cause the channel to be aborted, which
in turn may cause the other audio channel to be aborted.
However, the conversation can continue on the audio channel.
Such control relationships are enforced by the transport
protocol, and would influence resource allocation of the network,
e.g., bandwidth allocation (page 1364, column 1). The object-
oriented structure of the Multimedia Communications System (MCS)
leaves the door open for a variety of paradigms and protocols for
resource management, data transport and synchronization ( id.).
The Multimedia Transport Layer (MMTL) acts as a server and the
application (or user) acts as a client. The MMTL controls the
allocation of resources for data transport over various channels
of a connection, and for synchronization of data flowing in the
channels (page 1368, column 2).
As shown in figure 10, (page 1371) the failure of channel
ch2 and the degradation of channel ch 1 may cause the user to
redefine the control relationship between ch 1, ch2, and ch3. This
