A Routing Architecture for Scheduled Dynamic Circuit Services
A wide range of applications in the nascent field of cloud computing and in other fields require stable, low-delay wide-area connectivity together with capabilities of co-scheduling network and server resources. As a result, both research and commercial providers have recently started to deploy Scheduled Dynamic Circuit Services (SDCS) as a complement to their IP-routed and leased-line service offerings. Under such services, corporations, universities, or end-users dynamically place requests for a fixed-rate circuit lasting for a fixed duration, for either earliest possible usage or scheduled usage at some point in the future. The lack of adequate support for inter-domain routing and provisioning represents, however, a major hurdle to the full-scale deployment of SDCS.
