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.
