Applications routinely open multiple TCP connections. For example,
P2P applications maintain connections to a number of different peers
while web browsers perform concurrent download from the same web
server. Application designers pursue different goals when doing so:
P2P apps need to maintain a well-connected mesh in the swarm while
web browsers mainly use multiple connections to parallelize requests
that involve application latency on the web server side. But this
practice also has impacts to the host and the network as a whole. For
example, an application can obtain a larger fraction of the
bottleneck than if it had used fewer connections. Although capacity
is the most commonly considered bottleneck resource, middlebox state
table entries are also an important resource for an end system
communication.
This documents clarifies the current practices of application design
and reasons behind them, and discusses the tradeoffs surrounding the
use of many concurrent TCP connections to one destination and/or to
different destinations. Other resource types may exist, and the
guidelines are expected to comprehensively discuss them.
