Requirements
Higher speed end-to-end links
Site-to-Site Replication Service
- 100 Mbyte/s goal possible through NTON (SLAC-Caltech are working on this).
Multi-site Cached File Access System
- Will use OC12, OC3, (even T3) as available
- (even 20 Mbits/s international links)
- Need “Bulk Transfer” service:
- Latency unimportant
- Tbytes/day throughput important (Need prioritized service to achieve this on international links)
- Coexistence with other network users important. (This is the main PPDG need for differentiated services on ESnet)
- can be background, don’t want onerous scheduling
