An Integrated Resource Negotiation, Pricing and QoS
Adaptation Framework for Multimedia Applications
The new value-added Internet services provide
new business opportunities, but also present new challenges.
The providers have to be able to add new services quickly and efficiently,
and equip the network to meet the high quality and reliability expectations
and diverse requirements of the value-added services.
Our work is broadly concerned with scalable and efficient architectures
for delivering multimedia applications over the Internet reliably and with
high quality. We have designed and implemented a scalable service
framework that supports dynamic resource negotiation between users and
network, as well as between peering network domains.
It enables short-term commitment of
resources by the network and demand adaptation by adaptive user applications,
and the pricing of network resources based on usage, QoS and user demand.
The proposed protocol and schemes are particularly efficient
in supporting services where resources are scarce, such as
access networks, bottleneck web servers, and wireless
air interfaces. Our scheme has been shown to provide performance
benefits under high or bursty loads, and provide QoS expectations for
wide range of user applications. It improves network utilization and
user connectivity. It increases user benefit and network revenue, and
reduces service blocking rate.
The frame work consists of the following components:
- Conditioning the network to provide multiple services with certain
Quality of Service expectations even under high demand
- Short-term, dynamic configuration of network resources for better
response to user demand and more efficient
resource usage
- Pricing network services based on QoS (resources
consumed) and user willingness-to-pay
- Motivating rate and service
adaptation by applications with elastic demand through
congestion-sensitive pricing of certain services, while providing more
expensive services with static pricing for non-elastic users
The work incorporates
a dynamic resource negotiation protocol, RNAP. RNAP enables negotiation
between user applications and the access network,
as well as between adjoining network domains, and also enables the
distribution and collation of price and charging information.
