Abstract: A de-serializer, such as forming part of a SERDES, in which a point in time of receipt, on the serial data path, of receipt of a particular part of a data packet, such as an SOF, is determined from when that part is output on the parallel data path from knowledge of the clock controlling the parallel data path as well as which of the parallel lanes the part is output on.

Abstract: An apparatus and a method where a plurality of physically separate data receiving/analyzing elements receive data packets and time stamp these. A controlling unit determines a storing address for each data packet based on at least the time stamp, where the controlling unit does not perform the determination of the address until a predetermined time delay has elapsed after the time of receipt.

Abstract: An apparatus and a method for receiving and forwarding packets, where the packets are received by a number of adapters and fed to a common storage in addresses allocated by a controller. The controller is adapted to forward to the adapters requests and at the same time log which addresses have been allocated to each adapter. As a response to the request, the individual adapter forwards predetermined data to predetermined addresses in the storage so that the controller is able to update the available or the used addresses in the storage.

Abstract: The systems and methods described herein provide a redundant communication path. The systems and methods can provide a second source for the same data under many circumstances. These circumstances can include, for example, 1) when data incurs errors during transmission in the communication link network, 2) when a communication link in the communication link network experiences transient blockage, 3) when a communication link experiences prolonged or indefinite blockage, and 4) when an optical transceiver unit within the communication link network experiences a hardware failure and is unable to perform its tasks.

Abstract: In one embodiment, a method is provided. The method of this embodiment provides selecting one of a plurality of host transmit queues on a host memory by selecting an entry from a queue descriptor list on a network device, the selected entry being associated with one or more packets on the host memory, retrieving at least one of the one or more packets from the host memory, and storing the at least one of the one or more packets in a device transmit queue of the network device.
