摘要： A method of address resolution for the transfer of voice and voice data calls through multiple domains in a broadband data network is described. The implementation of broadband data networks as transport backbones for voice and voice data calls requires address resolution to determine the destination node for each call. Because of the projected frequency at which new access peripherals will be added to such broadband data networks, manual maintenance of translation tables is impractical. The invention therefore provides an automated method for address resolution which permits voice interface control units associated with the broadband data network nodes to automatically maintain the required translation tables. Next-hop resolution routing tables may be maintained at every node or only at nodes designated as signaling gateways between broadband data network domains. If the broadband data network is an ATM network, switched virtual circuits are set up in reverse from ATM destination nodes in order to reduce call admission and setup time. The advantage is automated maintenance of translation tables which may be tailored to meet the operating policy of network managers that control respective domains.

摘要： A method of forwarding data in a network switch fabric is disclosed. An incoming data packet is received at a first port of the fabric and a first packet portion, less than a full packet length, is read to determine particular packet information, the particular packet information including a source address and a destination address. An egress port bitmap is determined based on a lookup in a forwarding table and it is determined if the destination address belongs to a trunk group of trunked ports. The incoming data packet is forwarded based on the egress port bitmap, when the destination address does not belong to the trunk group. When the destination address does belong to the trunk group, a particular trunked port of the trunk group is determined and the incoming data packet is forwarded thereto. More specifically, the particular trunked port of the trunk group may be determined by calculating a hash value based on the source address and the destination value and selecting the particular trunked port based on the hash value. Additionally, a class of service for the incoming data packet is also determined from the particular packet information and a priority for forwarding is set based on the class of service.

The first data port interface supports a plurality of data ports transmitting and receiving data at a first data rate. A second data port interface is provided; the second data port interface supports a plurality of data ports transmitting and receiving data at a second data rate. A CPU interface is provided, with the CPU interface configured to communicate with a CPU. An internal memory is provided, and communicates with the first data port interface and the at least one second data port interface. A memory management unit is provided, and includes an external memory interface for communicating data from at least one of the first data port interface and the second data port interface and an external memory. A communication channel is provided, with the communication channel communicating data and messaging information between the first data port interface, the second data port interface, the internal memory, and the memory management unit. A plurality of semiconductor-implemented lookup tables are provided, with the lookup tables including an address resolution lookup/layer three lookup, rules tables, and VLAN tables. One of the data port interfaces is configured to update the address resolution table based on newly learned layer to addresses. An update to an address table associated with an initial data port interface of the first and second data port interfaces results in the initial data port interface sending a synchronization signal to the other address resolution tables in the network switch. As a result, all address resolution tables on the network switch are synchronized on a per entry basis.

摘要： The invention includes a service exchange platform, a service access unit, and a service provisioning system. The service exchange platform provides one or more trunk interfaces with public and private communications networks. The service access unit provides multimedia communications service including voice and data service to the tenant premises. The service provisioning system is a software platform for managing a network of service exchange platforms and service access units. Within the service exchange platform and the service access unit and/or in communications between them, a modified ETHERNET protocol is used. Specifically, the 48-bit MAC field in each ETHERNET packet is redefined to include a QOS indicator and ATM VPI/VCI type routing information. This enables rapid routing of packets throughout the system and maintenance of QOS for voice packets.

摘要： A device and method are disclosed for correctly restoring a read clock when there are a plurality of STM data stream transmission sources. In a CES device of an ATM communication system, ATM cells from respective connections, which are to be delivered to the same outgoing line, are accumulated in a reassembly buffer memory and a PLO control unit aggregates the amount of ATM cells accumulated in the reassembly buffer memory for each connection. Subsequently, the PLO control unit calculates the frequency of a read clock based on the amount of accumulated ATM cells for each connection. A PLO restores the read clock which is applied to read data from the reassembly buffer memory for delivery to an STM network.

摘要： A method for performing a protocol interfacing operation for a plurality of nodes in an IEEE1394 serial bus network. Upon initialization of an IEEE1394 serial bus due to node addition or deletion, each of the nodes formats a protocol identifier packet and sends it to the other nodes. A bus manager stores the protocol identifier packets of the nodes into a protocol map. Then, a source node sends a protocol query packet including a target node identifier to the bus manager to request the transfer of data. Upon receiving the protocol query packet from the source node, the bus manager retrieves a communication protocol from the protocol map and sends a protocol set packet including information about the retrieved communication protocol to the source node and a target node to perform the transfer of data between the source and target nodes through the communication protocol. Therefore, the data transfer can efficiently be performed with no necessity for checking protocols one by one.

摘要： A SOH (101) of a transmission frame of SDH (SONET) is terminated at a sender-side transmitter (3 or 4) and is added to remaining data at a receiver-side transmitter (4 or 3). At the sender-side transmitter (3 or 4), the remaining data (102, 103), including an administrative unit pointer (102) is converted into ATM cells and the ATM cells are sent out to an ATM network (2). After that, at the receiver-side transmitter (4 or 3), the remaining data is restored from the received ATM cells. As a result, operation, administration, and maintenance are independently performed over sections disposed at the input and the output sides of the ATM network (2). Further, processes (conversion to ATM cells, restoring SDH frames) are performed irrespective of the difference between the administrative pointer (102) and a payload (103), and the number of the signal paths (104) multiplexed in the payload (103).
