Abstract
Conventional distribution of real-time multimedia data uses multicasting or a series of relays and tunnels for unicast networks. The former is a capability not popularly enabled by a lot of networks while the static relays cannot readily adapt to changing network conditions and are potential bottlenecks in a heavily accessed system. This paper proposes a dynamic overlay framework for streaming multimedia data over heterogeneous networks. The overlay comprises a self-improving tree which is built from client relays on the fly and a lightweight server to manage the tree. The overlay provides a better QoS than conventional relays as it monitors the network and re-configures the tree to adapt to changing environments. Clients can switch parents for better QoS. The robustness of the tree is improved by using a spiral mechanism and failure of the lightweight server will not impact the data distribution functionality of the existing tree.
