Authorization-based Approach for Customized Automated Resource Provisioning Services

摘要

Combining the concept of software control with existing legacy network technology promotes new networking services with low capital expenditure. Currently, many testbeds and academic operators provide bandwidth on demand (BoD) services over layers 2 and 3 wide area network. BoD decreases operational expenditures and manual errors. However, administrators must continue to manually configure virtual circuits for different stakeholders to accommodate configuration conflicts, quality of service (QoS), and service policies. This paper proposes a BoD framework called AutoNET to provide a set of BoD services with independent abstract topologies, resource allocation, and different QoS levels. User authorization is employed to control the eligibility to access a given BoD service. AutoNET uses the extended On-Demand Secure Circuits and Advance Reservation System (OSCARS) as controller software and MultiProtocol Label Switching (MPLS) as a transport technology.
