When dealing with multimedia delivery, scalability,
efficiency and Quality of Service (QoS) are challenging features
for today’s networks. Overlay networks can compensate for the
lack of control over the network routers, but for real-world applications
overlay network performance is an issue.
This paper presents an efficient solution for software implementation
of overlay network nodes. A new, advanced Distributed
Linked Data Structures (DLDS) schema has been developed
to provide scalable per-flow resource reservation and fast,
searchless routing/forwarding table lookup. This schema has
been integrated in a new overlay network framework that features
hierarchical dynamic routing and QoS estimation based on
performance measures of the underlying network.
The proposed technique has been implemented and tested in a
large, realistic network simulation environment, and experimental
results are presented.
