摘要： An initialization of local buses 14a to 14n, a definition of topology and a management of isochronous resources are performed for every local bus. Each of portals 12a to 12n includes an asynchronous packet discriminator 215 which discriminates an asynchronous packet sent by a terminal device and transfers it. The portals 12a to 12n discriminate asynchronous packets sent by terminal devices in order to acquire isochronous resources and secure isochronous resources on different buses. The portals 12a to 12n transfer isochronous packets to different local buses by associating a received isochronous packet with a plug on the bridge bus side and a plug on the local bus side with an isochronous channel on the bus. Thus, the utilization efficiency of bus resource in a serial bus network is improved and a packet sent from a terminal device can be transferred to a different bus.

摘要： A method and data a network for routing data packets is described. Switches are connected in a three-dimensional architecture (11) to form a switching fabric providing horizontal data routing according to addresses and vertical data routing according to packet types. An allocation procedure is then executed to manage the bandwidth resources of said fabric, resulting with assigning routing tables at the switches and portals prior to forwarding the packets to the switch fabric, a hop-by-hop packet flow is then executed through said switches of said switch fabric. Packet flow is controlled by an output port having an output port state machine and an output port concentrator.

摘要： A method for reading data from an IEEE 1394 serial bus system and storing the data in a FIFO includes partitioning the FIFO into a plurality of registers, each having 32 register bits for the data and a single register bit for a control data bit. To manipulate the system such that reads on a data quadlet involve only one system read on a 32-bit system, a packet token is stored in the initial register in a data packet. This packet token includes the quadlet count in the data packet. The host system need only read the first register in the data packet, the packet token, to determine the number of data quadlets within the data packet. Thereafter, the control data bit need not be read such that only a single read operation is performed for each operation of the read pointer. The last register associated with the packet is the acknowledge register which contains information that is sent back to the transmit node in the system. Further, each data packet can be divided into partitions with a plurality of packet tokens. Each packet token has a defined quadlet count associated therewith, the packet tokens disposed at the beginning of each partition. The last partition has a Complete bit set equal to “1” to define that as a the last partition. In this last packet token, the acknowledge signal is stored.

摘要： A communication path control system is provided for use in a data network configured by a number of buses each of which installs at least one node as an isochronous resource manager (IRM) based on the IEEE 1394 standard. Adjacent buses are interconnected together by means of a bridge consisting of at least two portals, each of which has a connection counter for counting a number of receiving nodes for receiving stream packets being transmitted thereto from a transmitting node by itself. For establishment of a communication path, a device controller specifies all portals that lie in the communication path to request each of them to increment a value of the connection counter by null1null. For disconnection of the communication path, the device controller requests each of the specified portals to decrement a value of the connection counter by null1null. More specifically, each portal stores a communication path management table containing the connection counter, while the device controller stores a communication path management table that describes resources (e.g., bandwidths, channels) in connection with a connection counter with respect to each of buses corresponding to the communication path. At occurrence of bus reset on a specific bus, its corresponding portal proceeds to initialization of the specific bus, then, the device controller proceeds to re-securement or release of the resources.

摘要： A system for resolving packet errors and busy acknowledgments for packets in a ring network, to maintain continued packet distribution on the network with support for strongly ordered, nonidempotent commands. Each consumer node on the network maintains a record of the sequence of packets that have passed through that node, and the state of each of the packets at the time it passed through, including a record of the last known good packet and its sequence number. When a producer node detects an error condition in an acknowledgment for a packet, resends all packets beginning with the last known good packet. Each consumer node is able to process or reject the resent packets, including packets that may already have been processed, which it is aware of due to the packet and state records for all packets. Strong ordering is thus supported, since the sending order of packets can be maintained for processing due to the resends, and nonidempotent commands are supported due to the consumer nodes' ability to determine whether they have already processed a given packet, and to send an acknowledge-done reply if that is the case. A retry queueing system is used which allows the system to effectively interleave busy retry loops with an error retry loop, thus accommodating both error retries and busy retries while preserving strong sequential ordering, if desired, of the sent packets.

摘要： Messages on controller area network (CAN) buses are communicated over subsea links. Repeaters couple CAN buses to each end of a subsea link. The subsea link may be, for example, a twisted pair or a single wire with a sea ground. The repeater detects a direction of transmission, that is, whether a signal began on the CAN bus coupled to the repeater or on the subsea link coupled to the repeater. Signals from the CAN bus are conditionally transmitted to the subsea link depending on the detected direction of transmission. Signals from the subsea link are conditionally transmitted to the CAN bus depending on the detected direction of transmission. The repeater can operate at the physical layer without analyzing contents of the CAN bus communications.
