What is I-SHARe?
I-SHARe stands for „Information Sharing across Heterogeneous
Administrative Regions„
It is a tool for supporting the operations in a multi-domain environment
Makes the co-delivery of end to end links across multiple domains:
Easier
More efficient
Seamless
Quicker
Provides a shared information and tracking tool for NRENs’ operational
teams.
Better than email, phones.
Does not automate anything but facilitates co-operation.

What information does I-SHARe
hold?
Details of the customer’s requests
Contact details for the responsible
experts in each NREN
phone numbers, email addresses,
roles
Key information for every domains’
demarcation points
phone numbers, addresses,
working hours
Technical details of NNI @ of each
neighbouring Demarcation Points
Information about the progress of work
in the other domain
Check-lists

Example scenario
New link request for BIO SPACE project
1.
LAB_A_IT
2.
3.
Scientific laboratories LAB_A_IT and
LAB_B_PL are collaborating in BIO
SPACE project
A 10Gb/s connection was set up in the
past
A backup connection has been
requested (diverse path WRT the
existing one)
LAB_B_PL

Example scenario
GARR expert starts working with I-SHARe
LAB_A_IT
1. The expert checks the existing link
• looks at the route
• looks at the bandwidth
2. The expert inserts basic information on
the new requested link
• chooses the end-sites
• inserts GARR and PIONIER as
connecting domains
• inserts information about requested
E2E link
• sends an e-mail to PIONIER
LAB_B_PL

Example scenario
PIONIER’s turn
1.
2.
LAB_A_IT
3.
4.
5.
The expert checks PIONIER
information and looks at the data of
the end-site located in Poland
The expert writes an e-mail back to
GARR
The Ordering Coordinator is chosen
The OC takes care about check-list
maintenance
The OC calls a meeting to decide a
route

Example scenario
Finding a route and negotiating parameters
1.
2.
LAB_A_IT
3.
3.
4.
5.
User-Network-Interface (UNI)
and Network-Network-Interfaces
(NNI) are negotiated between
endsites and domains
Ordering phase ends and Setup phase starts.
Set-up phase goes analogically.
Experts planned
a route using
Cross Border
Fibre
SWITCH and
DFN were chosen
as intermediate
domains
The OC checks
„Route finding” on
the check-list

Advantages of I-SHARe approach
Central repository of information about E2E links in the multi-domain
enviroment
Supports people instead of automating their tasks
Helpful especially when new hardware has to be installed and experts
work needs to be coordinated
Does not make any decisions but facilitates it.
Tracks performed actions
Knows actual state of the E2E link
Integration with E2EMON monitoring tool

I-SHARe software
Developed by GEANT participants: PSNC, GARR, DFN, SWITCH
In scope of SA2 T5 activity that works on tools supporting multidomain
workflows
Current version 1.0 has been implemented in GN3
Prototype version tested in several NRENs during GN2
Central Server for E2E link management (web GUI)
Domain Application for registering participants
standalone application
a reference implementation of web services based data provider (socalled Domain Interface)

Deployments
Pilot deployment
DFN, GARR, GEANT (DANTE), PSNC and SWITCH
November 2010 – March 2011
Based on real E2E links
To collect valuable feedback and develop a production-quality
software
Operational deployment
Planned
Scheduled to 2011
Ready to be deployed in MANs
Each MAN acts as a separate domain
Rules stay the same
