Panel: "QoS Provisioning at the
Network Edge"
John Vicente
Intel Corporation / Columbia University
“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 abstraction
Panel 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 Network Architectures
• Open and horizontal
…enabling interoperability, open markets, flexibility
– Increasing network intelligence
– Standard APIs & programmable building
blocks
– Flexible, dynamic QoS control and
provisioning
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.
