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: Methods and systems for a resource reservation network that supports bi-directional co-shared sessions.

Abstract: A communication device configured to transmit and receive simultaneously, over the same wire, unidirectional high definition video and bidirectional data. The communication device includes a hybrid circuit coupled to a cable made of wires, and a transceiver. The transceiver is configured to transmit, over one of the cable's wires, Transition Minimized Differential Signaling (TMDS) data and source-to-sink direction of bidirectional data. The transceiver is further configured to receive the opposite direction of the bidirectional data over the same wire and simultaneously with the transmitting.

Abstract: A wired communication link to carry to one side a first transmission of unidirectional time sensitive application data, having a throughput of at least 1.1 Gbps, multiplexed with a first direction of a bidirectional data channel, and to carry to the other side a second transmission of a second direction of the bidirectional data channel. The first and the second transmissions are transmitted over at least one common wire, the frequency bands of the first and the second transmissions at least partially overlap, and the communication link guarantees correct reception order. As a result, the receiver that receives the multiplexed transmission can utilize a relatively small buffer that is enough to compensate for timing distortions and is not enough to rearrange the unidirectional time sensitive application data.
