Toward Reliability Guarantee VC Services in an Advance Reservation based Network Resource Provisioning System

摘要

The most representative research network in Korea, KREONET, has developed DynamicKL, an advance reservation based network service agent for user driven virtual circuit services. DynamicKL provides reservation, provisioning, release, termination, and inquiry web services for network resources by using an open standard network service interface (NSI), as well as web services for network resources by using a GUI interface. In addition, it has the RESTful web service Interface for Configuration and Event management (RICE) to support a protection management function for virtual circuits and reservations. In this paper, a protection management per virtual circuit (VC) for provisioned VCs and reservations is addressed in the DynamicKL framework, as a contribution to the VC protection management issue, which results in more manageable and reliable VC services compared to other advance reservation frameworks. An administrator can detect successful or unsuccessful VC protections in the event of a primary link failure and successful or unsuccessful VC retrievals after a primary link repair, by using RICE.
