    摘要： Line set-up detection circuit 22-1 detects N successive conformities in line information Sa from a network side line terminating set 1 and a signal Sb representing the result of detecting N successive conformities with an error correction code added thereto to the network side line terminating set 1. Network side line set-up control circuit 12 generates a line set-up permission signal Sc or a line set-up inhibition signal Sd on the basis of the signals Sb representing the result of detecting N successive conformities from all user's side line terminating sets 2-1 through 2-3 and transmits it to each of the user's side line terminating sets 2-1 through 2-3. User's side line set-up control circuits 24-1 writes the contents of line set-up primary memory 23-1 into line set-up main memory 25-1 when it receives a line set-up permission signal Sc and inhibits the contents of the line set-up primary memory 23-1 from being written into the line set-up main memory 25-1 when it receives a line set-up inhibition signal Sd.

    摘要： A network switch to support scalable and flexible access control list (ACL) lookup comprises a packet processing pipeline including a plurality of packet processing units each configured to generate a master key for an ACL lookup request to a memory pool and process a received packet based on ACL search results. The network switch further includes said memory pool including a plurality of memory groups each configured to maintain a plurality of ACL tables to be searched in one or more SRAM memory tiles of the memory group, accept and format the master key generated by the packet processing unit into a compact key based on a bitmap per user configuration, hash the formatted compact key and search the ACL tables stored in the one or more SRAM memory tiles using the formatted compact key, process and provide the ACL search results to the requesting packet processing unit.

    摘要： Method, apparatus, and systems for reliably transferring Ethernet packet data over a link layer and facilitating fabric-to-Ethernet and Ethernet-to-fabric gateway operations at matching wire speed and packet data rate. Ethernet header and payload data is extracted from Ethernet frames received at the gateway and encapsulated in fabric packets to be forwarded to a fabric endpoint hosting an entity to which the Ethernet packet is addressed. The fabric packets are divided into flits, which are bundled in groups to form link packets that are transferred over the fabric at the Link layer using a reliable transmission scheme employing implicit ACKnowledgements. At the endpoint, the fabric packet is regenerated, and the Ethernet packet data is de-encapsulated. The Ethernet frames received from and transmitted to an Ethernet network are encoded using 64b/66b encoding, having an overhead-to-data bit ratio of 1:32. Meanwhile, the link packets have the same ratio, including one overhead bit per flit and a 14-bit CRC plus a 2-bit credit return field or sideband used for credit-based flow control.

    摘要： A circuit switched switching system and method includes a plurality of matrix transposition memories. The memories permute the order of incoming and outgoing data, and thereby increase the efficiency of the switch. The switch and matrix transposition memories may be disposed in a satellite. The switch may further include batching circuits for grouping together data from a single terminal device for more efficient transmission through the switch and for more efficient error correction.

    摘要： In a multiplexing method of multiplexing communication signals from communication signal transmitting sections and transmitting a multiplexed signal to a multiplexed signal receiving section, each of the communication signals, an identification address preassigned to a predetermined signal identifying section through which a communication signal passes in a multiplexing system including the communication signal transmitting section and the multiplexed signal receiving section is added to each communication signal. The resultant signal is output. The identification address is extracted from each output signal. The respective communication signals are multiplexed on the basis of the extracted identification addresses. A multiplex apparatus, access network system, protocol termination apparatus, and multiplexing/demultiplexing apparatus are also disclosed.
