摘要： Methods and systems for enabling recovery of lost packets transmitted over a communication network. In one embodiment, a device includes a processor and a transmitter. The processor is configured to calculate a row parity packet (RPP) and a diagonal parity packet (DPP) for n packets. Each of the RPP, the DPP, and the n packets comprises n segments. The processor utilizes each packet, from among the n packets, to update parity values in the RPP and the DPP in such a way that each segment in the packet is used to update one segment in the RPP and at most one segment in DPP. The transmitter transmits the n packets, the RPP, and the DPP over the communication network. Receiving a subset of n members of a set comprising: the RPP, the DPP, and the n packets, enables recovery of two lost packets.

摘要： Methods and systems that enable recovery of a lost packet from an incomplete block transmitted over a communication network. In one embodiment, a system includes a first processor configured to: receive a block of packets during a period spanning a certain duration, calculate a parity packet (PP) for the block, and provide in PP an indication of the number of packets in the block, where the block comprises k

摘要： 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.

摘要： Methods and systems that enable recovery lost packets that were transmitted over a communication network. In one embodiment, a device includes a receiver and a processor. The receiver receives n packets that belong to a set comprising n+2 packets transmitted over the communication network, where the set includes: n data packets, a row parity packet (RPP), and a diagonal parity packet (DPP). Each received packet comprises n segments. Each segment of the RPP comprises a result of a parity function applied to a set comprising n segments, each belonging to a different packet from among the n data packets. Each segment of the DPP comprises a result of a parity function applied to a set comprising n segments, each belonging to a different packet selected from a group comprising the n data packets and the RPP. The processor may utilize the received packets to recover two lost packets.
