A method for evaluating an available bitrate over a path among one of at least two paths linking a first endpoint and a second endpoint, the path being called an evaluation path, is disclosed. The first endpoint is configured for sending data packets to the second endpoint, the second endpoint is configured for sending at each data packet reception an acknowledgment message to the first endpoint through one of the at least two path selected at each data packet reception. The method comprises, at the first endpoint, steps of: A method for sending at a second endpoint an acknowledgement message over a path among one of at least two paths linking a first endpoint and said second endpoint is further disclosed. Associated device for evaluating an available bitrate and device for sending at a second endpoint an acknowledgement message are disclosed.

Method for evaluating an available path bitrate based on an acknowledgement path selection

A method for controlling a packet transfer through a multipath session is disclosed. The method comprises a number of n paths linking a first endpoint to a second endpoint, n being an integer greater or equal to 2, i being an integer and 1&#x2266;i&#x2266;n; each path Pi being defined by a couple of addresses of a communication interface of the first and second endpoint; the first endpoint being configured for sending the packet to the second endpoint through anyone of the paths; the second endpoint being configured for sending an acknowledgment message through anyone of the paths when the second endpoint received a packet. According to the invention, the method involves, at the first endpoint and at a time t, steps of: A device for controlling a transfer of a packet through a multipath session implementing the method is further disclosed.

Control of packet transfer through a multipath session comprising a single congestion window

This invention relates to a system for adaptive streaming in a multipath environment comprising a plurality of servers being respectively capable of transmitting multimedia content in a RTP/RTSP environment through a respective data path to a client, wherein the client includes a controller means being capable of probing each of said data paths in order to determine a respective bandwidth associated to each of said data paths and to request a chunk of said multimedia content for each of said servers according to the respective bandwidth. In addition, the invention relates to a method for adaptive streaming in a multipath environment.
