Integration of Network Services Interface version 2 with the JUNOS Space SDK Radek Krzywania e-mail: radek.krzywania@man.poznan.pl Michał Balcerkiewicz e-mail: michalb@man.poznan.pl

NSI provides unified global service out of multiple independent local provisioning services Network Domain Provisioning Tool NSI CS interface

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: http://www.ogf.org/gf/group_info/view.php?group=nsi-wg https://forge.ogf.org/sf/projects/nsi-wg

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)

NSI CS Historical Milestones

Current NSI CS test-bed   Tool Number of sites running Organisations 1 AutoBAHN 2 GÉANT, PIONIER DRAC 3 CERN, CESNET, SURFNET DynamicKL KRLight 4 G-Lambda-A AIST 5 G-Lambda-K JGNX, KDDI 6 OpenNSA CERN, GLORIAD, NORDUENT, UvA 7 OSCARS Esnet

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.

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

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

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)
