Scheduled connections: Managing temporal constraints on broadband network resources

Abstract

Future broadband networks will provide end-to-end connections which span multiple networks, operators, domains and technologies. The ability to supply end-to-end connections depends on the ability to satisfy (in near real-time) end-user topology, schedule (availability of resources in the present or future), quality of service and cost constraints. This paper examines the problems imposed by schedule constraints, as they allow operators and service providers the ability to differentiate their offerings above the traditional connectivity, QoS, and cost basis. Such constraints are strongly linked to QoS issues, and also to maximizing the use of shared network resources and are therefore quite important for management of future broadband networks. In order to satisfy temporal constraints imposed by scheduled connections, both the management systems and managed resources involved must provide appropriate support. This paper presents an overview of several important management issues that are involved in the support of scheduled connections.
