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.
