Pricing communication services with delay guarantee

Although pricing communication services has received attention, there has been little work where quality-of-service (QoS) guarantees are incorporated into ex ante pricing of communication links. In recent years, however, data networks providing services with QoS guarantees have become quite popular. We study optimal pricing for communication links provided over packet-switching networks with explicit QoS guarantees in terms of an expected per-packet delay. We first develop a pricing scheme for multiple classes of service when the delay guarantees are fixed and exogenously determined and analyze this scheme with one and two classes. Subsequently, we extend this analysis to the case where a provider can choose her own QoS parameters. We also examine long-run pricing and capacity planning for one and two classes of service. Finally, we consider other QoS guarantees such as jitter, packet-loss ratio and maximum delay.
