Abstract
We first address the risk management problem in end-to-end service provisioning over the Internet. Towards this end, we utilize a contract-switching Internet abstraction, in which the ISPs expose themselves to other ISPs as a set of edge-to-edge contracts. Initially, we study the efficiency of inter-domain traffic engineering using the contract-switching paradigm. Next, we consider the Internet Service Provider's (ISP's) problem of providing end-to-end (e2e) services with bandwidth guarantees. We consider the risks arising from uncertain end-to-end user demand, the possibility of route failures and contract violations, and the uncertainty in the costs involved due to other participating ISPs. We develop path-vector based end-to-end contracting solutions that maximizes the ISP's profit subject to constraints on the risk of profit. In the path-vector based approach, an ISP uses its edge-to-edge (g2g) single-domain contracts and vector of contracts purchased from neighboring ISPs as the building blocks to construct, or participate in constructing, an end-toend "contract path". We develop a spot-pricing framework for the e2e bandwidth guaranteed services utilizing this path contracting strategy, by formulating it as a stochastic optimization problem with the objective of maximizing expected profit subject to risk constraints. We present time-invariant path contracting strategies that offer high expected profit at low risks, and can be implemented in a fully distributed manner. Simulation analysis is employed to evaluate the contracting and pricing framework under different network and market conditions.
