  Pricing of Internet Resources

Diagram of Internet PricingOur focus in this work is on dynamic pricing of network resources. The work is characterized by four aspects:

  • Pricing is dynamic, on a time scale that is slower than congestion control but quicker than connection access control.
  • Resources are allocated to users in a fashion that maximizes social welfare. Prices are used to signal the marginal utility of each network resource.
  • The network is assumed to support integrated services, and resource prices are often translated into QoS prices to efficiently support a diverse range of applications.
  • Users are assumed to be cooperative, not game-playing. Cooperation may be induced through charges to users.

Our goal is use network pricing to connect traffic characterization, scheduling, and connection access control. There is now a substantial body of work on traffic characterization and application requirements characterization, which will allow users to describe the QoS requirements of their traffic flows. There is also a substantial body of work on integrated and differentiated services network architectures, which will allow networks to give differentiated performance to these flows.

However, without some policy to manage QoS within the network, the network can not efficiently transform such user characterizations into network resource allocations and make intelligent decisions as to how to treat each traffic flow.

 

The following papers are some of the earliest work in the field of pricing of network resources. They assume the network has an architecture that allows for reservation of network resources, e.g. Internet's IntServ or ATM's virtual paths. Real-time services measure utility by the loss experienced on the network path, while non real-time services measure utility by the time required to transmit a file. Prices are set per unit effective bandwidth on each network link, so that each application can determine the QoS it should receive.

The next set of papers expands this framework to associate prices with both bandwidth and buffer. Real-time services measure utility by the combination of end-to-end loss and delay, and they request the combination of bandwidth and buffer that most efficiently achieves their desired loss and delay.

The final set of papers considers an architecture that allows for prioritization (rather than reservation), e.g. Internet's diffServ. The premise is that network pricing may be able to decide what priority each packet should receive, i.e. how to assign codepoints. Prices are associated with each codepoint, and users choose traffic rates on each codepoint on the basis of price and QoS.
