Next Generation Networks for HENP

• Rapid access to massive data stores
• Petabytes and beyond
• Balance of high throughput vs rapid turnaround
• Coordinate manage Computing, Data, Networks
• Seamless high performance operation of WANs
  LANs
• Reliable, quantifiable (monitored), high
  performance
• Rapid access to the data and computing resources
• Grid-enabled data analysis, production and
  collaboration
• Full participation by all physicists, regardless
  of location
• Important requirement good connectivity
• Grid-enabled software, advanced networking,
  collaborative tools
