- New visualization, topology, navigation, forecasting, event detection, alerting, and diagnosis tools for perfSONAR which will make perfSONAR increasingly attractive and useful and networkers and users dramatically more efficient in understanding and debugging network problems;
- Important testing, debugging and documentation for the perfSONAR collaboration (funded partially by the US);
- Closer collaboration of users such as SLAC High Energy Physicists, LHC (funded partially by the US) collaborators with network administrators at end sites and in the Internet Service providers;
- Increased coverage of worldwide networks for international debugging of network problems;.

\[1\] NIIT will be funded out of a separate grant from the Pakistan Higher Education Commission (HEC). \[2\] The perfSONAR framework is supported by the perfSONAR consortium ([http://www.perfsonar.net]) recently initiated by the joint collaboration of Internet2, the European Union-funded GEANT2 project, the DoE energy Sciences Network (ESNet), Georgia Institute of Technology (GaTech) and the Stanford Linear Accelerator Center (SLAC). Since NIIT is working in strong collaboration with SLAC, PERN shall be able to benefit from the experience of our collaboration by virtue of PETWORK. \[3\] Network diagnostics tools such as OWAMP, NDT, BWCTL (a scheduler for iperf) have proven to be vital for Internet2 to understand the performance trends and in solving network performance problems. \[4\] The Pakistan NIIT and National Center for Physics (NCP) sites are both building Grid clusters to provide services for the LHC, and so will need both excellent networking for data distribution, and perfSONAR in Pakistan to diagnose network problems end-to-end. |
