2. 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)

3. 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

4. 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

6. 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

8. 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)

9. 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)
