Abstract: A system for interfacing Ethernet with SpaceWire comprises a processor including an Ethernet MAC, and a bridge device connected between the processor and a SpaceWire subsystem or network. The bridge device comprises a SpaceWire physical interface that receives SpaceWire data packets, and an Ethernet MAC packet builder that includes digital logic for segmentation of the data packets into Ethernet compatible packet segments. An Ethernet media independent interface receives the packet segments from the packet builder and outputs the packet segments to the Ethernet MAC. The Ethernet media independent interface also receives Ethernet data packets transmitted from the Ethernet MAC. An Ethernet MAC packet extractor receives the Ethernet data packets from the Ethernet media independent interface and includes digital logic for performing reassembly of the Ethernet data packets into SpaceWire compatible data packets, which are sent to the SpaceWire physical interface for transmission to the SpaceWire subsystem or network.

Abstract: A data caching method for an Ethernet device is provided. The method includes: receiving data frames from various Ethernet interfaces and converting the Ethernet data frames received from the Ethernet interfaces into data frames having a uniform bit width and a uniform encapsulation format; maintaining a cache address in which data has already been written and a currently idle cache address in a cache; receiving the currently idle cache address and generating a write instruction and/or a read instruction for the cache and performing a write operation and/or a read operation so as to write the data received and processed by an IPC into the currently idle cache or to read data from the cache; and performing bit conversion and format encapsulation on the data that is read according to a read request and outputting the data subjected to the bit conversion and the format encapsulation through a corresponding Ethernet interface. A data caching system for an Ethernet device is also provided. By means of the data caching method and system provided herein, the expandability and the high bandwidth storage capacity of a network switching device can be improved, a high bandwidth utilization rate is achieved, and it becomes possible to improve bandwidth utilization rate based on traffic management.

Abstract: This invention relates to a design of an efficient buffer management model in order to increase the efficiency of data exchange between two process threads, - e.g. when implementing a network transport protocol stack. This invention proposes to use an interconnected system of different kinds of memory buffers (100, 101, 102), implemented as asynchronous read/write ring buffers ARWRB. These buffers are organized in a way, in which data can be stored into the buffer or fetched from the buffer essentially avoiding synchronization means like mutexes or semaphores. In contrast to the conventional buffer management model, three ring buffers, namely send ring buffer (100), send token ring buffer (101) and receive ring buffer (102), are used within the transport protocol stack.

Abstract: Described and claimed is a method for transmitting continuously created data items from an aircraft to a receiver. The data items are of a plurality of data types and each have a different priority. For each data type a live LIFO buffer and a main LIFO buffer are provided. In a regular operation mode continuously created data items are continuously stored in the main buffers. In a transmission operation mode continuously created data items are continuously stored in the live buffers, consecutive data packets are transmitted and for each data packet the data is selected from the buffers, wherein data items stored in live buffers are transmitted before data items stored in main buffers and data items of higher priorities are transmitted before data items of lower priorities. Further, a transmitter and an aircraft are described and claimed.

Abstract: A network device includes a memory with a first queue and a second queue. A timing module generates a first priority timing signal or a second priority timing signal based on a clock signal. The clock signal is shared between the network device and other network devices in a non-arbitrary network. The network device includes a deblocking shaper or a blocking shaper. The deblocking shaper (i) forwards first protected data from the first queue, and (ii) generates a deblocking signal based on a first frame signal and the first priority timing signal. The blocking shaper (i) forwards one of second protected data and unprotected data from the second queue, and (ii) generates a first blocking signal based on a second frame signal and the second priority timing signal. A selector module selects the first frame or the second frame based on the deblocking signal and the first blocking signal.

Abstract: A system and method for processing commands to network target devices (56) through an SCSI router (54) in a Fibre Channel network (10) having a plurality of Fibre Channel hosts (52). The system and method are implemented in the SCSI router and include receiving a command from one of the hosts and, if the command is for a transfer of data larger than a threshold size, streaming the data to the target device. When a presize memory block is free, a data block is requested from the Fibre Channel host that issued the command. The SCSI router receives data blocks and stores them in a FIFO queue until an initial number of data blocks are stored in the FIFO queue. Data blocks are then forwarded to the target device until a trigger number of blocks remain in the queue. Additional data blocks are requested and received from the host simultaneously with the forwarding of data blocks to the target device. The target device requests data blocks from the SCSI router until all of the data associated with the command has been transferred.

Abstract: This disclosure relates to communicating on a wireless channel in the presence of an interference source. A receiver accesses the channel to perform a sequence of energy detections. The interference source is modelled as cyclically transitioning into and out of an inactive state and as cyclically transitioning, when out of the inactive state, between a first active state, in which the interference source is active and creating interference on the channel, and a second active state, in which the interference source is active but creating a substantially lower level of interference on the channel. Based on the sequence of energy detections, large and small time scale metrics are determined. Transmission of data by a transmitter is in dependence on the estimated metrics.
