Streamline: An Architecture for Overlay Multicast

Date Added: May 2009

The authors propose Streamline, a two-layered architecture designed for media streaming in overlay networks. The first layer is a generic, customizable and lightweight protocol which is able to construct and maintain different types of meshes, exhibiting different properties. They discuss two types of overlay networks and explain how the first layer protocol builds these networks in a distributed manner. The second layer is responsible for data propagation to the nodes in the mesh by constructing an optimized diffusion tree. In order to cover the vulnerabilities of the diffusion tree, they propose a masking mechanism which enables the nodes to instantly switch to alternative data paths when necessary.
