Technical Issues Working Group
Chairs: Erik-Jan Bos, SURFnet & Gigi Karmous-Edwards, NCSU
Secretary: Peter Szegedi, TERENA
Goals
The goals of the working group are to design and implement an international LambdaGrid infrastructure, identify which equipment is being used, what connection requirements are required, and which functions and services should be provided. The following work items have been identified:
- Define standard terms for GLIF technical resources.
- Identify and document the best current practices within GLIF.
- Development of a database of GLIF technical resources, combined scheduling mechanisms.
- Investigate automation of control plane mechanisms.
- Define which services should be provided.
It was agreed in January 2008 this group should absorb the activities of the former Control Plane Working Group.
Meetings
The next meeting will be held on 13-14 October 2010 at the 10th Annual Global LambdaGrid Workshop in Geneva, Switzerland.
