摘要： A packet scheduling system for use in a switching node of a high speed packet switching network. Incoming packets are enqueued in connection queues. Each connection is classified as red (exceeding traffic profile) or green (within traffic profile). QOS priority is also identified for each connection. Packets are dequeued for transmission as a function of priority class and connection class. Higher priority class connections have priority over lower priority class connections. Within a given priority class of connections, green connections have priority over red connections. Round robin scheduling is used for packets from connections in the same priority and connection class. In addition, a dynamic priority coupling mechanism is provided to prevent red higher priority traffic from blocking green lower priority traffic.

摘要： Adaptive bandwidth allocation for Non-Reserved traffic over high speed transmission links of a digital network is operated through regulation of data packet transfers over network nodes/ports including input/output adapters connected through a switching device. A network node is assigned with a Control Point computing devise (CP) storing a Topology Data Base containing an image of the network. This Data Base is periodically and at call set up updated by Topology Data Base Update messages (TDUs) including an Explicit Rate parameter for link l indicating the current available bandwidth on link l, and a parameter NNRl indicating the number of Non-Reserved connections on link l. This information are used within each Adapter to periodically regulate the transmission bandwidth assigned to each Non-Reserved traffic connection within the network. To that end, each adapter is provided with an Access Control Function device for each attached connection (data source) and a Connection Agent (CA) getting, on request, required current link informations from the attached Topology Data Base.

摘要： A method and an apparatus implementing a shaping function in a fixed length cell switching network node adapter supporting output lines in a telecommunication network. The adapter includes a Time Division Multiplexing (TDM) table where each entry is a pointer to a first cell of a queue of cells stored in the adapter for a given traffic. When a new traffic is established, the TDM table is updated. A placement device performs the pre-computation of the best placement of the entries reserved for one traffic in the TDM table. The placement device minimizes the Cell Delay Variation as computed by a Generic Cell Rate Algorithm (GCRA--ITU standard organization) policer. The Cell Delay Variation (CDV) is defined as the deviation of the placement of the cells from their ideal position in an output stream, the ideal placement being when the cells are spaced with an interval corresponding to the period of traffic negotiated at traffic establishment time. The preferred embodiment includes a scheduler which reads the TDM table and fetches the corresponding cell in the queue storage to send the cell onto the output line via a line interface unit.

摘要： An apparatus and method for multicasting messages stored in data buffers of a data storage. Each message is composed of data stored in a plurality of the data buffers. Each data buffer is controlled and mapped to a unique direct control block (DCB) which stores information characterizing the data buffer. By chaining the DCBs variable length, messages can be generated. Indirect control blocks (ICB) stores information characterizing the data or messages duplicated and points to a DCB. A field in the DCB carries a count representing the number of times the message is to be duplicated.

Said method includes the steps of successively transmitting sequences of real and imaginary components of a signal exhibiting an uniform amplitude (i.e. flat) spectrum; receiving and storing sequences of echoes of each of said sequences of components; calculating the fast Fourier transform of complex sequences obtained from the stored sequences of echoes; rotating the terms of the Fourier transform; calculating the inverse transform of the sequence obtained by rotating said terms; and sorting the terms of the inverse transform to derive therefrom the values of the initial coefficients of said filter in said echo canceller.

摘要： An improved split-band coder reduces signal-processing time, thereby reducing echo delay time and listener confusion. The voice-originated signal to be transmitted over a transmission line is sampled and digitally coded at a relatively high bit rate; the spectrum of said signal is then partitioned into p sub-bands. The sample stream of the signal so-filtered and partitioned into p sub-bands is split into blocks of samples, or portions, of a given time duration. A requantizing device proceeds for each block to the requantizing of the samples in each sub-band by means of requantizing parameters derived from the samples of the preceding sample block, whereas new requantizing parameters are determined and stored with a view to requantizing the following sample block. The requantized samples in the different sub-bands are multiplexed, and transmitted over the transmission line, together with the values of the highest amplitude samples in each sub-band.

摘要： A method and system for implementing secure network communications between a first device and a second device, at least one of the devices communicating with the other device via a firewall device, are provided. The method and system may include obtaining an encryption parameter that is shared by the first device, second device and firewall device. A data packet sent by the first device may then be copied within the firewall device, so that decryption of the copy of the data packet within a portion of the firewall device may take place. In particular, the portion of the firewall device in which decryption takes place is defined such that contents of the portion are inaccessible to an operator of the firewall device. Thus, scanning of the decrypted copy of the data packet for compliance with a predetermined criterion may take place within the firewall device, without an operator of the firewall device having access to the contents of the data packet to be transmitted. Thereafter, the original data packet can be forwarded to its originally intended recipient.
