摘要： A system and method of reassembling packets from traffic flows in a network element is provided. Each of the packets has at least one data part. The method includes the steps (1) queuing each of the data parts of the packets of traffic flows in a single reassembly queue in a sorted order, the data parts of each of the packets being continuously grouped without data parts of another packet being interleaved therein and (2) reassembling the data parts of each of the packets queued in the single reassembly queue.

摘要： A packet switch. The switch includes a plurality of port cards. Each port card has an unstriper which reassembles stripes of a particular packet. The switch includes a plurality of fabrics (FABRIC # 1 to FABRIC #N). Each fabric operates on only a same respective fragment of a packet received from one of the plurality of port cards. Each of the plurality of fragments is connected to each of the plurality of port cards. A method for switching packets. The method includes the steps of sending a sync signal from a port card to a plurality of fragments. Then there is the step of sending fragments of a packet as stripes to the respect plurality of fabrics (FABRIC # 1 to FABRIC #N). Next there is the step of operating on the fragments after they are received at each respective fabric by each respective fabric only after the respective fabric has received the sync signal.

摘要： A network device having a plurality of ports including address resolution logic (ARL), a first switch, a second switch, and a CPU. The first and second switches include groups of ports which are a subset of the plurality of ports and are numbered by different numbering schemes, rate control logic for performing rate control functions related to switching data packets between the network ports, and local communications channels for transmitting messages between the groups of ports and the rate control logic. The first switch is configured to generate a rate control message and relay the rate control message to the second switch, and a first link port of the first switch is configured to generate a second rate control message based on the first rate control message, relay the second rate control message to the second switch, where the second rate control message is different than the first message.

摘要： An architecture for a SONET network element, such as a hybrid STM/ATM add-drop multiplexer. The disclosed system includes an interconnection system for a network element, including a line unit slot, a switch fabric slot, and two or more service unit slots. The line unit slot is connected as a hub to the switch fabric slot and the service unit slots in a first star interconnection configuration. The switch fabric slot is connected as a hub to the line unit slot and the service unit slots in a second star interconnection configuration. The star interconnection configurations provide fault isolation between different units, and allow for replacement of failed units without interfering with the links of other units to the hub. In a preferred embodiment, the switch fabric slot and one of the service unit slots comprise the same slot, thus permitting flexible configuration of the device within a minimal space. In a further illustrative embodiment, a control unit slot is provided in the interconnection system, and connected as a hub to the line unit slot, the switch fabric slot, and the service unit slots to form a third star interconnection configuration. A service unit is also disclosed, including a first backplane interface for connecting with an ATM star interconnect configuration within the network element, and a second backplane interface for connecting to an STM star interconnect configuration within said network element. The service unit further includes a third backplane interface to connect with a control star interconnect configuration within the network element.

摘要： A transcoder converts data between a telephony data format and a packet data format. The transcoder comprises: a digital logic telephony data engine receiving telephony data for the transcoder and transmitting telephony data for the transcoder, the digital logic telephony data engine comprising a frame accumulation buffer; a digital logic packet engine receiving packet data for the transcoder and transmitting packet data for the transcoder; a digital signal processing complex coupled to the digital logic telephony data engine and the digital logic packet engine, the digital signal processing complex comprising an array of digital signal processors; and a host processor coupled to the digital logic telephony data engine and the digital logic packet engine, wherein the digital logic telephony data engine, the digital logic packet engine, and the digital signal processing complex perform media channel processing, wherein the host processor performs control channel processing. A switch switches time division multiplexed (TDM) data and packet data from input ports to output ports. The switch comprises: a plurality of input ports receiving data, wherein each data comprises either TDM data or packet data; a plurality of output ports transmitting switched data; and a shared memory coupling the input ports to the output ports. The shared memory sequentially receives the data from the input ports, and switches a sequentially received data from a respective input port to a respective output port. Switching of packet data by the shared memory has no latency or jitter effect on switching of TDM data by the shared memory.

摘要： Disclosed are a frame for multiplexing multi-traffic frames of layers 1 to 3 on a same carrier wave and an apparatus thereof.
A frame 400 is constituted of an overhead 410 and a payload 420. The overhead 410 is constituted of: a data length identifier 430 indicating a frame or a payload length; a flow identifier 440 indicating an attribute of the frame 400; and a frame header overhead error check (FHEC) 450 storing a result obtained by converting bytes from the head to a specified M-th byte of the frame 400 into a numerical value of n bytes according to a certain coding method. As for a length of the payload 420, up to a maximum length computed from the data length identifier 430 of the overhead can be stored. In the payload 420, traffics for the layers 1 to 3 can be accommodated. Even if the ATM cell and the frame 400 are multiplexed, since coding methods for the FHEC 450 and the HEC are different, the ATM cell and the frame 400 can be extracted individually.

摘要： Upon initialisation, a VPC is set up between edge nodes. A control processor 9 of each node creates an IP address/VPC mapping table 95 using IP routing information and an address mapping table mapping correspondence between IP addresses and ATM addresses and supplied by a network management system 5. A gateway 3c assigns a VCC to each packet input to the network 4a. A sending-side edge node inputs the packet to the VPC corresponding to its destination by referring to the IP address/VPC mapping table 95. A transit node 2 performs packet switching over VP. A receiving-side edge node 1b transfers each packet to the gateway 3b corresponding to its destination. If a series of packets meet a predetermined condition in a given edge node 1, its control processor 9 sends VCC information to input interfaces 6 of the edge node 1 so that the packets are switched by an ATM switch 8 in the edge node 1 without intervention of the control processor 9.
