| 20090041015 | METHOD FOR ALLOCATING DATA PACKET TRANSMISSION AMONG MULTIPLE LINKS OF A NETWORK, AND NETWORK DEVICE AND COMPUTER PROGRAM PRODUCT IMPLEMENTING THE METHOD - A method for intelligently distributing packets of a data stream to multiple links of a network for simultaneous transmission via the multiple links, and for periodically re-allocating the distribution, achieves higher network throughput. The method has particular application for streaming audio-video traffic on a home local area network that has a source device, like a media server PC, and a destination device, like a digital TV. One of the links is assigned as the primary link (PL), and another link is assigned as a backup link (BL). Periodically a signal is sent from the source device over each link to the destination device and the round-trip travel time (RTT) for the signal and response for each link is measured. The RTT for a link is a good measure of the current end-to-end link status and generally will change during the time that the data stream is being transmitted as a result of certain events, such as traffic load and interference. The RTT on the PL (RTT-PL) and the RTT on the BL (RTT-BL) are used to adjust the allocation of packets simultaneously transmitted on the links. | 02-12-2009 |
