Project Steering Committee
On-demand Infrastructure Services Provisioning Workshop, OGF 28, Munich, Mar 15th2010
• Beyond a UNI, towards a App-to-Net i/f• Generalized semantics to describe
• the functional characteristics of both IT sites and NEs (exported from LICL)• i.e. resource types, capabilities and availabilities
• E.g. sites, attached services, capabilities and capacities of network, computing and storage elements, etc.
• also the non-functional service characteristics• Workflow descriptions• Interaction properties • Service Level Agreements• Pricing/charging models• etc.
a service that allows the provisioning of network and IT resources in a single-step, through a set of seamlessly integrated procedures
• ASON/GMPLS core specs• ITU-T SG15 work on ASON and Transport Ethernet• OIF for ASON Network Interfaces (UNI, E-NNI sig+rout.)• IEFT RFCs & I-Ds for • signalling (G.RSVP-TE)• routing (G.OSPF-TE)• recovery mechanisms • support for multiple switching technologies (MRN/MLN)• PCE architecture and inter-PCE comms
• OASIS SOA application requirements and framework• OGF: NSI, OCCI?
Starting point of work: prototyping & testingStarting point of work: prototyping & testing
• A number of existing platforms to be extended/used• For GMPLS+/PCE+ (protocol stacks in Linux controllers)• For std GMPLS/PCE (protocol stacks embedded in optical
nodes)
• … and a solid R&D test-beds background from the team
• Telco SME: Nextworks (NCP WP Lead)• Telco manufacturers: ADVA, Alcatel-Lucent Italy• Pan-European Carriers: Interoute• Service Providers: SAP AG• Telecom Operators & NREN: Telefonica I+D, Polish PTT, PSNC• Universities and Research Centers: i2CAT, Univ. Essex, Univ. Amsterdam,
