Abstract
Packet Classification and Scheduling Technologies for
Multimedia Content Delivery Network
Although there are many approach to
deploy a multimedia content delivery
network, the so called “Overlay
Network” approach should be one of
the main streams. In this network
architecture, the core routers and core
switched may play no important role, as
long as the backbone bandwidth is sufficient. And thus QoS may not be
required. Hence, we focus on the
research of classification and
scheduling algorithms required on the
Edge Router that determine the QoS
(such as packet loss ratio, delay,
bandwidth) between the P2P
multimedia application users ( such as a
portable terminal in Home Multimedia
network ) and the core/overlay network
nodes. The Edge Router is also
required to filter unsolicited packets so
that multimedia content delivery can be
realized with better quality.
Hence this project completes the
design and implementation of an
efficient/effective classification and
scheduling algorithm that can better
support the multimedia content delivery.
The major differences between our
approach and the IETF DiffServ
framework is the new definition the
classification and scheduling which is
feasible in Linux platform, and the
concept of Ack spacing in Qos control.
We plan to support premium class
service with a complexity limited
solution on Linux platform. Our
implementation result will be test in a
Gigabit Ethernet based testbed so that
the capacity and performance of the
Linux QoS router can be measured.
