A technique for manipulating one mobile device (MD) from a plurality of MDs to maintain the transmitting rate of packets of an upload session to one Internet Protocol (IP) server from a plurality of IP servers is disclosed. The technique may utilize an upload-rate-controlling server that is communicatively coupled between the plurality of MDs and the plurality of IP servers and is configured to respond to missing one or more packets by using SACK and DSACK messages. Other embodiments may estimate the delay of the uploaded packets and adapt the value of a new-receiving window such that the delay of the uploaded packets is smaller than the value of the time threshold used by intermediate nodes for dropping packets.

Method and system for upload optimization

Controlling of a three-way handshake by a proxy server, while using dual-stack process. The proxy server is coupled between a plurality of surfer-equipment (SEs) and a plurality of webservers over IPv4 and/or IPv6 networks. The proxy server can obtain from a first SE, over the IPv6 network a first SYN packet that requests to establish a TCP connection over IPv6 with a first webserver. Next, the proxy server may check a list-of-webservers and determine whether a connection between the proxy-server and the first webserver over IPv6 will be established successfully. Accordingly, the server can determine whether to send a first SYN-ACK packet toward the first SE and send a second SYN packet over IPv6 toward the first webserver, or, to send the second SYN request over IPv4 toward the first webserver.

Method and system for implementing IPv4 or IPv6 in a proxy

A technique that leads a surfer-equipment (SE) to switch to a lower bitrate is disclosed. The technique is implemented at an intermediate node between the SE and a domain. Leading the SE to switch to a lower bitrate is implemented by throttling one or more protocols each carried by one or more connections that carry packets of a multi-level-adaptive-bitrate (MLABR) media.

Method and system for bitrate management

The technique for the delivery of a media file is adjusted based on current constraints on a channel being used by a device requesting the media file. The media file is copied and the various copies are optimized for different constraints. Then, the media file is delivered by examining the current constraints on the channel and transmitting the media data from the copy of the media file that is most suitable for the current constraints. In some implementations, the constraint is the bandwidth of the channel and the copies of the media file are based on different bit rate adjustments.

Method and system for providing bit rate adaptaion to video files having metadata

A technique and system that generates transcoded media files from requested original compressed media files, and then transmits the transcoded media files to a requester rather than the original compressed media files. Advantageously, the disclosed solutions provide a more bandwidth efficient downloading of media files to a requesting device. In addition, the disclosed solutions also fully support the seek function that is typically employed in media player devices. By correlating the requested original compressed media files time-wise with the generated transcoded media files, seek requests generated by a requesting device can be mapped to the appropriate or a close proximity to the transcoded media file.
