Description

Multipath streaming system and method for providing at least one stream of data packets for media and/or video from a transmitting node to a receiving node The present disclosure relates to a system, method, and computer program product for providing a stream of data packets for media and/or video from a transmitting node to a receiving node. Streaming data packets for media and/or video over the Internet from a transmitting node to a receiving node can sometimes be problematic if the stream of data packets is interrupted or delayed, as people often want to watch media and/or video, such as sports events, in real time. This makes the streaming of data packets for media and/or video more vulnerable compared to transmitting data packets where time is not critical or data packets that may arrive out of order. Streaming data packets for media and/or video over the Internet from a transmitting node to a receiving node via a point-to-point network path can be affected by network interruptions due to a lack of data packet redundancy if the point-to-point network path is congested or affected by network availability. Although various error correction methods can be used to minimize data packet loss, data packets routed by the Common Internet Protocol over the Internet from a transmitting node to a receiving node can become congested and/or delayed when error correction methods are ineffective, negatively impacting the user experience, for example, when consuming real-time media or watching real-time video. The above-mentioned objects of the present invention, as well as additional objects, features, and advantages, will be more fully understood by referring to the following exemplary and non-limiting detailed description of embodiments of the present invention, together with the accompanying drawings.
