4. What is Network Services Interface (NSI)
OGF NSI WG objective is to design and standardize a unified protocol framework for defining multi-domain services in heterogeneous environment of IT resources.
NRENs and operators can dynamically manage their networks with single domain oriented tools, which has no common interface between each other.
The NSI CS is about to open single domain provisioning tools for interaction in order to provide global dynamic services.
Up to date information can be found at:

5. NSI Features Topology abstraction and distribution for global view
Set up/tear down a global circuit
Advance and immediate reservations support
Clear state machine for reservation processing and resources management
Authentication of communicating agents
Easy agents/reservation state validation
Daisy chain and hierarchical tree communication models support
Implementation independent (related to developer preferences and NMS used in a domain)

8. NSI CS roadmap for operational deployments
GÉANT Bandwidth on Demand cloud
supports NSI CS v1.0 (managed by
AutoBAHN provisioning tool).
NSI CS v2.0 will be adopted as soon
as available.

9. NSI CS roadmap for operational deployments
GLIF AutomatedGOLE initiative is willing to use NSI based dynamic
provisioning in the production network in 2013

10. Interested in using NSI infrastructure
NEXPReS/EVLBI project, which require dynamic high throughput network infrastructure for correlating radio telescopes observations
CO-Universe project, which is building self-organization of ad-hoc collaborative environments
LHC Open Network Environment (LHCONE) project, which requires dynamic infrastructure for distributing Large Hadron Collider experiment data.
Global Lambda Integrated Facility (GLIF) which provides shared model for global network connectivity among NRENs (AutomatedGOLE project)

17. How to access JUNOS SPACE SDK
Applications hosted by Junos Space expose their APIs with REST interfaces
By default APIs are protected from unauthorized use (X509 certificates required)
Plug and Play application management
Typical Junos Space application consists of 3 elements:
Junos Space Application
Other Junos Space Applications
Business Logic
REST API
Web Site
Users

22. Current state and planned features
Current implementation features:
NSI CS v2.0 (standard draft) implementations (yes, we are trying to follow the standard under construction)
NSI agent is a separate entity accessing JUNOS Space SDK via REST API (you can have other JUNOS Space applications running in parallel)
Discovery of interconnected EX switches (Devices Management API)
Remote configuration of EX switch by NSI agent (Script Management API)
Simple GUI
Planned features:
More scalable topology discovery
GUI extensions for administrators (more control over JUNOS network to NSI NML topology conversion process)
