Abstract: A technique is disclosed for delivering packets that carry data from a plurality Internet Protocol (IP) servers toward a plurality of mobile devices (MDs). The disclosed technique postpones or drops data packets that are directed toward a certain MD. The downloaded process can be resumed when the application that is running at the certain MD needs the content that is carried by the postponed data packets. Consequently the delaying process is unnoticeable to the user that uses the application that running over the MD. Thus, the QoE of the user of that MD is not affected.

Abstract: A technique comprising a Just-In-Time (JIT) marking element and a JIT agent is disclosed. The JIT-marking element and the JIT agent are configured to deliver one or more packets in the direction toward a first MD just-in-time (JIT) prior to the time in which an application, at the first MD, needs to handle the content that is carried over the certain one or more packets. The JIT-marking element is configured to add a JIT indication that indicates when to deliver the marked one or more packets toward the first MD and transmit the marked one or more packets toward the JIT agent. The JIT agent is configured to process the JIT indication, remove it and accordingly deliver the one or more packets toward the first MD.

Abstract: A technique to deliver Personally Identifiable Information (PIT) of a first subscriber from the plurality of subscribers that reside in a private network toward a first server from the plurality of IP servers that reside in a public network wherein the first server is involved in at least one transaction with the first subscriber is disclosed. In addition a Network-Address Translator (NAT) is used in order to allocate to the first subscriber a public IP address. Further, the communication between the first subscriber and the first IP server is encrypted. An example embodiment of the disclosed technique may impersonate the first subscriber and send the PII over an impersonated packet.

Abstract: 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.

Abstract: A technique, to keep alive one or more radio connections over a cellular network in order to carry downloaded data packets sent in a burst mode, is disclosed. In burst mode the flow of the data packets has a pattern with repeating two types of periods, an active period and a silent period. During an active period a plurality of data packets are sent and during a silent period almost no data packets are sent. The technique is implemented by an intermediate network element (NE) that is configured to send, during the silent period, a keep-alive signal (KAS) toward a relevant CD. The KAS can be a TCP acknowledgement, for example.

Abstract: A technique to increase the throughput (TP) of transmission of IP packets over a cellular connection between a mobile device (MD) and a network element (NE) is disclosed. An example embodiment of the disclosed technique starches the time period of the slow start phase of a TCP/IP connection between the MD and the NE. Another example embodiment divides the slow-start phase into two or more slow-start-sub phases. Yet, another disclosed embodiment is configured to add, during the slow-start phase, an extra number of bytes that are embedded in extra-number-of packets (ENoP) wherein the value of the ENoP is decreased when the RTT is increased.

Abstract: 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.

Abstract: 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.

Abstract: Content delivery to end user devices (EUD) is controlled by transmitting content portions at a controlled flow. The time for the EUD to process the data is used to control the flow. The first portion is transmitted to the EUD and the amount of time to process the first portion is noted. Threshold values to stop and start transmissions are examined prior to the transmission of each content portion. If the amount of data remaining to be processed by the EUD is below the stop transmission threshold, transmission continues with the next portion. If the amount of data remaining to be processed by the EUD is above the stop threshold, transmission is either stopped or retarded. When it is determined that the amount of data remaining to be processed by the EUD is above the start transmission threshold, transmission is started or continued.

Abstract: 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.

Abstract: 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.
