摘要： A cross connect network is utilized in order to switch packets of information among a plurality of network nodes. Each of the plurality of network nodes generates a multiplexed data signal, where each multiplexed data signal includes several channels. The cross connect network routes the data packets based upon which channel each packet is in when it arrives from the network node, rather than based upon the address in each packet. Thus, the need to read the address and switch the packet at each switching stage in the cross connect network is eliminated.

摘要： A congestion control method and apparatus for use with a communications link comprising a plurality of N channels. A plurality of at most N-1 queues are sequentially polled, and data is output therefrom to the communications link, thereby leaving at least one remaining channel. After the at most N-1 queues are polled, a determination is made as to which of the at most N-1 queues is closest to a data overflow condition. The remaining at least one channel is then utilized to transmit data from the queues which are closest to overflow.

摘要： The present invention concerns a method and apparatus for memory and channel sharing in a communication switching network which uses packet switching. In one form of the invention memory and channel sharing is provided within a packet switch. The packet switch includes a memory for storing a plurality data packets and a router that routes data packets from the memory to a particular output port. The router is operable to route data packets to either a dedicated output port, in other words, an output port defined by the virtual circuit path of the data packet, or a shared output port. In another form of the invention memory and channel sharing is provided by a packet switch in conjunction with a terminal. Protection lines which are provided in transmission systems can be used as the shared channels.

摘要： A plurality of M receivers are utilized to receive a plurality of N channels from various incoming multiplexed data signals, N.gtoreq.M, where each incoming data signal arrives on a separate wavelength and comprises several channels. Each of the M receivers, in sequence, receives a separate one of the N channels, thereby M of the N channels. The process then repeats for the next M channels, in the same sequence as the first M channels. The repetitions continue until all N channels are received.

摘要： Security is improved in a communication system in which a communication connection is established when a user who has received a software button on his computing device (a Recipient) clicks on the button. When a Recipient first actuates a software button, a basic type of communication connection is established, during which the Recipient's identity can be verified. The Recipient then establishes a personal identification code, which he will have to provide upon future actuations of the software button. The system then enables other types of communication connections to be established by the Recipient. After the Recipient actuates the software button and verifies his identity, the system remembers the identity and location of the computing device he is using. When the Recipient subsequently actuates the software button, the identity and location of his computing device are checked, and verification of his identity is suppressed if they have not changed.

摘要： A user performing a search on a computing device, for example with a browser application, is provided with one or more software buttons on the display of the device. The buttons are created based on the subject matter of his search. As the user searches, his queries are stored. Should the user actuate a software button, real time communication, for example a telephone call, is established with an adviser, who receives a copy of the user's search queries on his computing device.

摘要： A data stream is converted from a synchronous transfer mode (STM) to an asynchronous transfer mode (ATM) by extracting data of a number of payload signals from the data stream, writing data of the payload signal into a random access memory (RAM), separately recording address locations of the data of each of the payload signals in separate buffers, directing the RAM to separately read the data of the payload signals, and attaching a cell header to the data read from the RAM to form ATM cells.

摘要： Significant throughput improvement is achieved for an input queued packet switch using output port schedulers by permitting the output schedulers to recycle or reassign cell transmission times from input ports which are unable to use them. When an output scheduler assigns a cell transmission time to an input port and that input port is unable to use the assigned transmission time due to a scheduling conflict, for example, the input port makes a new request for the same output port during the next subsequent request period and then returns the unusable transmission time assignment back to the output scheduler. The output scheduler stores the returned transmission time in a separate queue for assignment to later requests for the particular output port. Throughput performance is improved from 58% (without time slot recycling) to 92% (with time slot recycling) for random packet cell traffic models.

摘要： A communications network comprising a plurality of "subnetworks" multiplexed onto a single communications medium. A separate group of NIU's communicate on each predetermined "subnetwork", and each NIU also includes a tunable transmitter for transmitting data to NIU's of other subnetworks. Data from a user equipment is transmitted via the tunable transmitter if it is destined for an NIU from another subnetwork, and via a fixed transmitter if it is destined for an NIU on the same subnetwork. In one embodiment, fiber optics is utilized in order to provide a high speed network with tunable lasers.

摘要： The bandwidth required for a regularly occurring signal, such as a television signal, as received from a signal source can be substantially reduced by not transmitting each and every one of the horizontal scan lines. Rather, firstly, one or more selected lines may be transmitted and, secondly, instead of transmitting the remaining, unselected lines, a signal representing a predetermined arithmetic difference among predetermined ones of the scan lines may be transmitted. The bandwidth may be further reduced by a time expansion of the time interval of the selected line signal and by a time compression of the time interval of the differential signal. The bandwidth required for each regularly occurring signal as received from each of a plurality of N signal sources may be more efficiently used by time compression multiplexing the respective time expanded and time compressed signals.
摘要翻译：通过不传输水平扫描线中的每一个，可以显着地减少从信号源接收的诸如电视信号的规则发生的信号所需的带宽。相反，首先，可以发送一个或多个所选行，其次，可以发送表示预定扫描线之间的预定算术差异的信号而不是发送剩余的未选择行。可以通过选择的线路信号的时间间隔的时间扩展和差分信号的时间间隔的时间压缩来进一步减小带宽。从多个N个信号源中的每一个接收到的每个经常发生的信号所需的带宽可以通过对各个时间扩展和时间压缩信号进行时间压缩复用来更有效地使用。
