Abstract: Methods and systems for uneven segmentation of data packets to reduce retransmission penalty accumulated as a result of having to retransmit one or more of the last segments. The method includes segmenting a data packet into segments of different sizes, with generally larger segments in the first half and smaller segments in the second half, and transmitting the segments over an intermediate communication link to another node. The transmission of the segments begins before receiving the entire data packet, and retransmission of a corrupted segment takes place as soon as an indication indicative of the corrupted segment is detected.

Abstract: Methods and systems for smooth switching of video sources. One method includes the steps of: Inferring that first and second network paths share a common link that has insufficient bandwidth to carry both the respective first and second incoming high-definition uncompressed videos (HD-UVs) generated by first and second real-time video encoders (RT-VEs). And synchronizing a smooth switching between the first and second incoming HD-UVs by: indicating the first and second RT-VEs to increase their first and second compression ratios to ratios that enable the common link to carry both the first and second compressed videos; indicating a video switcher to perform the smooth switching between the first and second corresponding outgoing HD-UVs; indicating the first RT-VE to stop sending the first compressed video after the smooth switching; and indicating the second RT-VE to decrease the second compression ratio.

Abstract: Methods and systems for rapidly recovering from a serious interference. One method includes the following steps: transmitting, by a transmitter to a transceiver over a communication channel, ongoing data at a fixed data rate above 100. Mbps; receiving, by a receiver from the transceiver, an indication indicating that the transceiver is experiencing a serious interference; responsive to the indication, reducing data rate at which the transmitter transmits; storing excess data that cannot be sent during the period of the reduced data rate; and increasing the data rate, at which the transmitter transmits, to a level that enables it to transmit, within less than 1 millisecond from the moment of reducing the data rate, both the stored excess data and the ongoing data at the fixed data rate.

Abstract: Methods and systems for fast switching between bi-directional co-shared sessions having different network paths over a resource reservation network. Embodiment of one method includes: creating a bi-directional parent session (Sp) between first and second session partners, creating a bi-directional derivative session (Sd) between the first session partner and a third session partner, and reassigning a predetermined amount of co-shared network resources (PA-CSNR) assigned to the Sp using the following steps: (i) sending a first message to request the second session partner to stop using the PA-CSNR, (ii) sending a second message to register whether the PA-CSNR are assigned to the Sd, and (iii) sending a third message to allow the third session partner to utilize at least some of the PA-CSNR for the Sd.

Abstract: System and method for a resource reservation network that switches fast between bi-directional co-shared sessions having different network paths. A session creation module (SCM) creates a bi-directional parent session (Sp), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop. The SCM further creates a bi-directional derivative session (Sd) between the first session partner and a third session partner, by: allocating network resources to the Sd over a third network hop, and not allocating specifically for the Sd all the network resources required for the Sd over the first network hop. And the network is able to switch between the Sp and the Sd within a duration that is less than half the duration required to create the Sd.

Abstract: Methods and systems for providing a virtual HDBaseT® link. In one embodiment, a first switch transmits packets over an Ethernet network that includes one or more hops. The payload of each of the packets includes an HDBaseT® T-packet belonging to an HDBaseT® session. A first processor sets, for each packet from among a plurality of the packets, a timestamp value in the packet to correspond to the time at which the packet is transmitted by the first switch. A second switch receives the packets over the Ethernet network. A second processor calculates a clock correction value based on the timestamps in the plurality of packets, and utilizes the clock correction value to perform at least one of the following: (i) control transmission, by the second switch, of data in T-packets in the payloads of the packets, and (ii) recover a source clock of native media delivered over the Ethernet network.
