Understanding Latency - A Root Cost and Mitigation Approach<br>
Joe Touch, USC/ISI<br>
Call For Participation - Los Angeles, CA, Friday August 25, 2017</p>
<p>“Time is fleeting,” it has been said. Time delay, or latency, is
the one metric that drives most others. It defines what it means
to be <strong>fast</strong>, and limits us to what is <strong>fast
enough</strong>.</p>
<p>Latency has always been a key part of network performance, but
recently it has been elevated to a primary focus for electronic
traders, search engines, name servers, data centers, and home and
network routers. Increases in network bandwidth, router forwarding
speed, and end system computational resources have helped bring
latency to the forefront as a primary concern. New protocols are
emerging to address latency as a primary issue, including Delay
Tolerant Networking (DTN) and bufferbloat mitigations.</p>
<p>This tutorial presents a comprehensive exploration of the impact
of latency on communication. It explores time as a budget to be
spent, over-spent, rebated, and conserved. We explore the root
causes of latency: generating data, transmitting it, processing
it, and the impact of resource sharing through multiplexing and
aggregation, as well as corresponding ways to mitigate each of
these causes. We also explore ways to mask latency that cannot be
reduced and to avoid incurring its cost in the first place. This
tutorial provides examples of real system design and
implementations, as well as exploring several key case studies to
provide practical experience that attendees can immediately apply
to their own systems.</p>
