Path Selection in Streaming Video Over Multi-Overlay Application Layer Multicast
- 總結
- Application-layer multicast (ALM) has grown tremendously in recent years, making the distribution of bulk data such as streaming video economically feasible for small companies and even individuals. The efficiency of an ALM network depends on its data distribution overlay, which is constructed based on metrics such as round-trip time (RTT) measurement between peers. However Internet measurement experiments revealed that RTT is far from an accurate estimator of bandwidth availability and as such, may lead to sub-optimal performance in the constructed ALM overlays. This invention tackles this problem by developing a new in-band bandwidth probing tool which can estimate achievable bandwidth, i.e., the data throughput that can be realized between two peers over the transport protocol employed (e.g., TCP).
