12
Applications

• Infrastructure
• WARP - Web Authentication Resource Protocol
• QoS Drivers
• IP-based video conferencing
• Moderate latency requirement 250ms
• medium bandwidth 5-10Mbps
• Voice over IP
• Low-Moderate latency
• Low bandwidth
• Nanomanipulator (Remote microscopy)
• Requirement for very low latency lt50ms
• Medium-High bandwidth

13
QoS Suppport

• Overprovisioning
• Only a partial solution
• Not that interesting
• Not very scalable
• Need Applications drivers

14
Multicast

• DVMRP and PIM Dense support now
• PIM Sparse RSN
• Important for scalability
• Indirect affect on QoS

15
Future Plans

• Add links
• IBM (soon)
• Nortel
• Alcatel
• Interpath (in progress)
• dWDM
• Video and data applications
• Packet over light
• Upgrade to OC192 and beyond
