Low Delay Communication and Multimedia Applications
Figure 5.16 Comparison between: (1) Standard SCTP (primary path only: f

); (2)
Symmetric delay-centric SCTP (primary round-trip path ( f

) has the lowest RTT;
(3) Asymmetric SCTP (paths f

, f

); (4) Delay of CBR background cross traffic
(with no SCTP traffic) was also plotted for reference.
indicates a pressure for more bandwidth by the current flow. Depending on the traffic
characteristics of the flow, the lowest-delay path selection method may also be able
to deal with the increase in latency due to additional bandwidth requirements of the
flow itself. This ...
