摘要： A communication node comprises a receiver for receiving packets and a routing device for routing the received packets to one of two output ports. For each output port, the communication node further comprises a classifier for classifying a received packet based on its traffic characteristic and storing that packet in a corresponding queue for that traffic characteristic, and a concatenated packets preparer for concatenating n received packets from each queue to form a concatenated packet to be transmitted by the associated output port, where the maximum of n is determined based on the traffic characteristic of the associated queue.

摘要： A method for checking an ATM point- to-multipoint connection between a paging sender and a plurality of paging receivers in a mobile communications system is disclosed. The paging sender transmits a check cell to the paging receivers through the point-to-multipoint connection at regular intervals. Each of the paging receivers determines whether the check cell is received within a second predetermined time period longer than the first predetermined time period. When the check cell has not been received for the second predetermined time period, a connection resetting request is transmitted to the paging sender to reset the point-to-multipoint connection.

摘要： At each network node, a packet classification unit makes a judgement to transfer only a packet necessary to be processed by software to a packet processing program processor and transfer other packets directly to a routing processor. Processing history information indicating the process history executed at each network node on a network route is transferred to the other network nodes so that other network nodes can store the processing history information in respective processing history repository table. Each node refers to this table and further transfers only the packet necessary to be processed by software to the packet processing processor.

摘要： In a data transmission system connected to a communication network, a packet disassembling section disassembls a data packet into non-final cells with a predetermined data length for a cell stream, and adds a final cell after the non-final cells for the cell stream. A cell transmitting section sequentially transmits the non-final cells and a plurality of the final cells to the communication network as the cell stream.

摘要： An object of the present invention is to improve transmission efficiency of a communication system for forming a transmission frame from a plurality of packets to perform communications using the transmission frame and reduce transmission power required to maintain an error rate. Headers of the plurality of packets are coupled to each other with redundancy information deleted therefrom so as to form a header part of the transmission frame. Further, payloads of the plurality of packets are coupled to each other so as to form a payload part of the transmission frame. A forward error correction code used for the header part and a forward error correction code used for the payload part are respectively attached to the transmission frame in isolation.

摘要： An ATM communications system. The system includes an ATM network on which ATM cells of ATM packets travel. The system includes a host having a host memory mechanism preferably having cache lines which stores the cells. The system includes an interface having a receive memory mechanism which stores a partial packet comprising a plurality of cells received from the ATM network. The receive memory mechanism aligns with the host memory mechanism so every transfer from the receive memory mechanism of the plurality of cells to the host memory mechanism fills the host memory mechanism along cache lines of the host memory mechanism. The interface has a bus which connects to the host on which communication between the host and the interface occurs. The interface is connected to the ATM network. A method for sending ATM cells over an ATM network. An interface for a host to receive ATM cells from an ATM communication network.

摘要： The telecommunication network is composed to a greater degree of ATM exchanges (ATM) and to a lesser degree of STM exchanges (STM). Information coming from an STM exchange (for example, STM1) and to be communicated to a further STM exchange (for example, STMy) via an ATM exchange (for example, ATM1) is packeted in message cells of the same length as those message cells used for the transmission between ATM exchanges in order to reduce the packeting time for the through-connection across the ATM exchange (ATM1). However, respective message parts of a plurality of STM time channels (K1 through K4) that are to be through-connected to the same ATM exchange output are multiplexed in a message cell.

摘要： Information is transmitted between a multiplicity of subscribers as components of traffic in an integrated services network, (ISN), in which the information traffic consists of a multiplicity of media types according to the different subscribers including voice, video, and data traffic component types. The traffic component types in the form of portions of respective information streams to be transmitted from subscribers at an entry point of the ISN are assembled into the payload of each of a sequence of composite frames for transmission through the ISN. The traffic component types subjected to such assembly are limited to those destined for subscribers at the same exit point of the ISN. Traffic component types within the composite frame payload are grouped in sets of adjacent channels of fixed bandwidth so that each group is limited to channels containing traffic components of the same type, with each channel assigned in its entirety to a selected subscriber. Any unused bandwidth is compressed out of the composite frame payload before the frame is launched into the ISN, by eliminating channels assigned to then-inactive or only partially active subscribers.

摘要： Method and apparatus for information communication during call connections between subscribers adapted to transmit and receive multimedia information at a pair of endpoint nodes of a fast packet switched network, the endpoint nodes being connected by a network path including at least one transit node traversed by links of the path. The multimedia information is conveyed as traffic consisting of a plurality of component types from among voice, video and data traffic component types each associated with a different subscriber at one of the endpoint nodes. A succession of composite frames conveying information is launched from each of the endpoint nodes to the other of the pair on the network path, with each of the frames configured to contain a plurality of fixed size channels representing bandwidth allocations for each of the traffic component types. Each channel is assigned to a subscriber of the respective traffic component type at the endpoint node from which the composite frame wa launched for the duration of that subscriber's respective call connection. The composite frames are dynamically reconfigured by releasing and reassigning channels at each of the endpoint nodes when necessary to accommodate changes in traffic flow in the network.

摘要： A method of assembling a plurality of frames including cell/packet-formatted data according to a predetermined frame format for transmission in a communication signal in a wireless or satellite environment. The method begins by assembling a data payload for each frame having a first variable size, including at least one of a partial data cell/packet and a complete data cell/packet. Then, for each frame a block code having a second variable size is generated for use in error correction. Each frame is provided with a frame header which defines aspects of the frame. Finally, the data payload, the block code and the format header are combined to form a frame corresponding to the plurality of frames, the format header defining a first portion of the frame, the data payload defining a second portion of the frame and the block code defining a third portion of the frame.
