Proactive Resource Provisioning
Allocating resources in communication networks to QoS flows can require an undesirable delay or cost. As demand churns readjusting wavelength allocation in optical networks, Label Switched Path (LSP) reservations in MPLS networks, QoS connections in two-tier ad hoc networks, and Service Level Agreements (SLAs) between peering autonomous systems are just a few scenarios where delays or costs in making adjustments suggest a proactive approach to resource allocation. The authors consider the general problem in light of a case study of the last scenario by engineering a dynamic Service Level Agreement (SLA) negotiation scheme between peer Autonomous Systems (ASes) that implement DiffServ per domain behaviors.
