The problem Users are unaware of network resources and abilities to reach distant infrastructures They don’t know how to set up connection, who to contact, when expect it to be ready Users expect simple mechanism for fast connection setup Users need high bandwidth connection globally (multi-domain and heterogeneous)

Current State of the Art The are multiple network provisioning tool which are: Single domain, or Multi-domain, yet restricted to the usage of the same tool Tools are dependent on network technologies Tools are adjusted to particular domain requirements Vendor specific tools are restricted to particular hardware and technology, usually single domain purpose

NSI So, why NSI DRAC OSCARS OpenNSA DynamicKL Objectives: To deliver a single global network provisioning interface, which can unify multiple tools, technologies, and domains To deliver network infrastructures as a service to both novice and expert end users To introduce automation into multi-domain bandwidth services NSI DRAC OSCARS OpenNSA DynamicKL

Vocabulary NSI – Network Services Interface = Framework for multi-domain resources reservation protocols, defines message schema, general messages headers, processing principles NSI CS – NSI Connection Service = Protocol for network provisioning, part of NSI framework There will be more NSI XX protocols/services developed soon

NSI implementation NSI v1.0 is described in an OGF standard document is publicly available A WSDL definition of communication API is created, based on the standard A Web Services based communication between NSI agents is used The NSI package can be attached to any provisioning tool by programmers The solution is language independent (currently there are both C++ and Java code coexisting in the testbed)

NSI v1.0 features NSI CS protocol provides the following features: Requesting a connection between any predefined end-points (reserve) Reserving resources for a connection planned in advance (reserve) Provisioning a connection (provision) Releasing a connection resources (release) Terminating a reservation at any time (terminate) Reserving Initial Reserved Auto Provision Scheduled Provisioning Porvisioned Releasing
