[Nsi-wg] Connection services in ION and ESnet..

Hi all- In our GN3 SA2-T1 wg regarding the Bandwdith on Demand service, we were discussing bandwidth granularity requirements. Could folks from ESnet and I2 comment on what you think appropriate granularity should be for these types of connection services and why? In the SA2-T1 group, applications such as FTPs, videoconferencing, etc were brought up - indicating a wide range of possible bandwidth requirements... Any thoughts or experiences would be appreciated. Jerry
