Abstract
Differentiated Service is intended to achieve
scalable service differentiation within the network. A
protocol with its QoS semantics left up to off-line
service level agreements (SLAs) between the network
and application, it is inapplicable to mobile
environments: (1) lacks real-time QoS feedback from
the network to the application; (2) cannot guarantee
SLAs under dynamically changing network conditions;
(3) forces the application to actively probe the network
for QoS measurements thereby needlessly consuming
bandwidth; and (4) can only provide network
conditions information in the near past, thereby
diminishing its utility. We introduce Predictive
DiffServ, a novel missing design point in the space of
QoS network services, as an adaptable mechanism
intended to provide the application with real-time, in-
band predictions of network conditions, and enable the
application to autonomously reconfigure its
requirements in response to these conditions.
Contributions include the concept, properties,
architecture and API of Predictive DiffServ.
Additionally, we identify newly enabled application
services, and portray quantitative results.
