Issue on Convergence
We focus on the integration of peer-to-peer
strategies and simple object access protocol/extensible markup language (SOAP/XML) for
inter-domain, user-driven provisioning in an automatic switched optical
network/generalized multiprotocol label switching (ASON/GMPLS) network. To the
soft-permanent connection (SPC) defined in ASON networks, a user-management interface is
added to allow direct negotiation between the users and the management system. Moreover,
the management system combines SOAP/XML and simple network management protocol (SNMP) to
communicate with a GMPLS control plane that is responsible for rapid connection
establishment, including routing and resource management. The management system is
distributed and integrates a communication interface ( the internal management
interface, I-MI) based on SOAP and on the peering strategy Chord to perform provisioning
related actions. Experimentation results with an ASON/GMPLS testbed assess potential
suitability of the overall approach for service provisioning due to its low delays and
high flexibility.
