From the introduction: We envision an internet architecture that allows flexible, fine-grained, dynamic contracting over multiple providers. With such capabilities, the internet itself will be viewed as a “contract-switched” network beyond its current status as a “packet-switched” network. A contract-switched architecture will enable flexible and economically efficient management of risks and value flows in an internet characterized by many tussle points where competition for network resources takes place. Realization of such an architecture heavily depends on the capabilities of provisioning dynamic single-domain contracts which can be priced dynamically or based on intra-domain congestion. Implementation of dynamic pricing still remains a challenge, although several proposals have been made. Among many others, two major implementation obstacles can be defined: need for timely feedback to users about the price and determination of congestion information in an efficient, low-overhead manner.
The chapter is organized as follows: In the next section, we position our work and briefly survey relevant work in the area. Section 3 introduces our contract-switching paradigm. In Section 4, we present PFCC and POCC pricing architectures motivated by the timescale issues mentioned above. In Section 5 we describe properties of distributed-DCC framework according to the PFCC and POCC architectures. Next in Section 6, we define a pricing scheme edge-to-edge pricing (EEP) which can be implemented in the defined distributed-DCC framework. We study optimality of EEP for different forms of user utility functions and consider effect of different parameters such as user’s budget, user’s elasticity. In Section 7, according to the descriptions of distributed-DCC framework and EEP scheme, we simulate distributed-DCC in the two architectures PFCC and POCC. With the simulation results, we compare distributed-DCC’s performance in PFCC and POCC architectures. We then extend the pricing formulations to an end-to-end level in Section 8. We finalize with summary and discussions in Section 9.
