Panel: "QoS Provisioning at the Network Edge"
John VicenteIntel Corporation / Columbia University
USENIX Special Workshop on Intelligence at the Network Edge
Fisherman’s Wharf, San FranciscoMarch 20, 2000
“What level of intelligence at the edge will be sufficient to achieve QoS?”
• Timing considerations
– Consumer driven
– Industry evolution
• Network architectural considerations
• Level of programmability
• Degree of abstractionPanel Q: Have we resolved IP-based QoS?
– Is network programmability a solution for IP QoS?
Ubiquitous IP Infrastructure
• Convergence, integration and efficiency– Multi-service aggregation devices
• QoS, security, provisioning and network management
– ToS, 802.1p, DiffServ, MPLS, RSVP, bandwidth broker(?) – or a hybrid
– Policy-based management & COPS• Configured (management scale) policies to provision,
service differentiate and perform bandwidth segmentation
– Packet content-based metering & provisioning
• Open and horizontal…enabling interoperability, open markets, flexibility
– Increasing network intelligence
– Standard APIs & programmable building blocks
– Flexible, dynamic QoS control and provisioning
Open Network Architectures
Programmable Internet Platform
• Network automation and customization….enabling privacy, personalization and autonomy (i.e.,
programmability and QoS)
– Network shares computation with the end systems• Advanced middleware & programmability models• Unified APIs and common network abstractions
– Automate the networking design, deployment process– Ultimate network abstraction =>Programmable virtual
networks• Transforming the “edge”
Updates
OPENSIG’2000 will be hosted by Intel in October of this year.
The Intel IX Architecture is a new approach to designing networking and telecommunications equipment based on reprogrammable silicon and open interfaces.
