Abstract: A network of switches with a distributed name server configuration and push/pull caching of remote node device information is disclosed. The network comprises a first switch coupled to a second switch. Each of the switches directly coupled to corresponding node devices. The first switch maintains a database of information about its local node devices. The second switch maintains a information cache about remote node devices, and periodically verifies that the cache information matches the database information on the first switch. The second switch preferably notifies node devices directly coupled to the second switch of state changes after notification messages are received from the first switch, and after mismatches are detected between the cache and the database. The second switch preferably responds to any queries about remote node devices by accessing the cache. In this manner, name server traffic overhead may advantageously be reduced in a robust, efficient manner.

Abstract: An improved arrangement is described for maintaining throughput of data packets over a cellular packet network from an Internet server to an end user machine during handoff of a mobile subscriber unit from a first base station to a second base station. The end user machine conventionally generates, in response to successive bytes from the server, acknowledgment signals including where applicable a “zero” acknowledgment signal that advertises a closed receive window at the end user machine and that is effective to pause transmission of data from the server. In response to a handoff start signal from the subscriber unit, a gateway unit associated with the first base station sends to the server a simulated zero acknowledgment signal to pause such transmission. Upon completion of handoff, an actual non-zero acknowledgment signal stored at the gateway unit at the start of handoff is applied to the server to resume transmission from the server to the end user machine.

In one example, the techniques may involve dynamically adjusting the size of a contention region in a MAP interval in which upstream time slot allocation is conveyed by a MAP message broadcasted by a cable modem transmission system (CMTS) to cable modems (CMs) sharing a common upstream DOCSIS channel. By adjusting the size of the contention region in the MAP intervals based on measured traffic parameters, the system can be dynamically responsive to different upstream traffic scenarios and thereby exploit maximal upstream data throughput continually.

Abstract: A processor is programmed to reduce a problem of adding a new connection to a time-space-time (TST) switch of a communication network into a problem of graph theory, and to solve the problem using a heuristic instead of an exact algorithm. A solution, if provided by the heuristic, is used to rearrange the connections in the TST switch. Several embodiments of such a programmed processor reduce a connection rearrangement problem of a TST switch into any one of the NP-complete problems (such as the vertex coloring problem or the boolean satisfiability (SAT) problem). In some such embodiments, the processor is programmed based on the Brélaz heuristic to find a solution to the vertex coloring problem. In other embodiments, other heuristics, such as a genetic algorithm, may be used.

Abstract: A signal router routes N inputs to M outputs. All inputs signals are ultimately applied to a data buss by spreading across multiple buss lines and time multiplexing. The data are read from the buss and written in identical images to K random access memories. The memories are addressed and read according to a different schedule for each of K output signals that are ultimately demultiplexed to M outputs. As each RAM image is read, another RAM image is written and vice versa. Since each RAM image contains the same data, the generation of signals from each RAM to supply each of the respective K output signals can be done at a rate that is substantially more independent of the input, buss, or RAM write operations than prior art techniques permit.

Abstract: An apparatus and method for expeditiously steering a received communication (e.g., packet, cell, frame) to one or more communication streams. When a new communication stream is opened on a network interface circuit or other Primary Point of Attachment (PPA), the protocol to which the stream is bound is used as a Service Access Point (SAP). A hierarchy of SAP nodes (e.g., a binary tree) is constructed, with each node corresponding to a unique SAP. Each node includes its corresponding SAP value, a count of the number of communication streams bound to the associated protocol, and a reference to those streams. When a communication is received, its SAP is extracted and the hierarchy is searched for a matching node. The communication is then forwarded to each referenced stream.

Abstract: The present invention provides a stall avoidance mechanism that may be used alone or in conjunction with an ambiguity avoidance mechanism in an ARQ protocol. Both mechanisms decrease data delays and increase data throughput rates. Stall avoidance is accomplished by determining whether a stall condition exists with respect to receiving a missing data unit. In one example, only a single timer is needed to avoid stalls. Retransmission ambiguities may be avoided using a retransmission window in the transmitter and/or a receive window in the receiver. Although each mechanism may be used independently of the other, a preferred example embodiment uses a stall avoidance timer, a retransmission window in the transmitter, and a receive window in the receiver.

Abstract: A method and system for associating a switched virtual circuit (SVC) connection request from an access port in an asynchronous transfer mode (ATM) network to a subscriber and optionally registering an address of the access port in relation to the subscriber. The method and system include receiving a signaling protocol message requesting the SVC connection from the access port, determining whether the signaling protocol message contains subscriber authentication data and, when authenticated, establishing the SVC connection. Furthermore, the SVC connection may be established only if service policies corresponding to the subscriber retrieved from a database indicate that the subscriber is entitled to make SVC connections. The method and system further include registering an address of the access port in the ATM network by substituting the address of the access port for an original subscriber address.

Abstract: An internet router is implemented as a network fabric of fabric routers and links. The internet router receives data packets from trunk lines or other internet links and analyzes header information in the data packets to route the data packets to output internet links. The line interface also analyzes the header to define a fabric path through the router fabric. The internet packets are broken into flits which are transferred through the router according to a wormhole routing protocol. Flits are stored in fabric routers at storage locations assigned to virtual channels corresponding to destination internet links. The virtual channels and links within the fabric define virtual networks in which congestion in one virtual network is substantially nonblocking to data flow through other virtual networks. Arbitration is performed at each fabric router to assign packets to virtual channels and to assign virtual channels to output fabric links.

Abstract: A method is provided for selecting a data source for transmission on one of several logical (virtual) lanes embodied in a single physical connection. Lanes are assigned to either a high priority class or to a low priority class. One of six conditions is employed to determine when re-arbitration of lane priorities is desired. When this occurs a next source for transmission is selected based on a the specification of the maximum number of high priority packets that can be sent after a lower priority transmission has been interrupted. Alternatively, a next source for transmission is selected based on a the specification of the maximum number of high priority packets that can be sent while a lower priority packet is waiting. If initialized correctly, the arbiter keeps all of the packets of a high priority packet contiguous, while allowing lower priority packets to be interrupted by the higher priority packets, but not to the point of starvation of the lower priority packets.

Abstract: A system manages a buffer having a group of entries. The system receives information relating to a read request for a memory. The system determines whether an entry in the buffer contains valid information. If the entry is determined to contain valid information, the system transmits the information in the entry in an error message. The system may then store the received information in the entry. In another implementation, the system stores data in one of the entries of the buffer, removes an address corresponding to the one entry from an address list, and starts a timer associated with the one entry. The system also determines whether the timer has exceeded a predetermined value, transferring the data from the one entry when the timer has exceeded the predetermined value, and adds the address back to the address list.

The packet parser supports a plurality of packet encapsulation formats and uses directed distance graph syntax for graphical representation. At each node, the packet parser isolates and compares a packet header word with either a number of associated masked values or a number of ranges to find a match.

A pointer is incremented as transition from the source node to the destination node is made. The packet parser is adapted to make a transition to a destination node from any number of source nodes, one or more of which may be a destination node for others of these source nodes.

Abstract: Training signals can be chosen based on stored prior connection information to reduce the use of extra tones in transmitted training signals and thereby improve receiver performance. By choosing training signals based on the stored prior connection information, it is possible to make the training signals indirectly a function of the loop impairments. One advantage of this scheme is that we can choose to omit certain tones in the training signals, based on previous connection information, on a loop-by-loop basis. For example, in an ADSL Transceiver Unit-Central office end (ATU-C) device, per-local-loop prior connection information may be employed to select DMT tones to be included in downstream training signals. Similarly, in an ADSL Transceiver Unit-Remote terminal end (ATU-R) device, prior connection information may be employed to select DMT tones to be included in upstream training signals.

Abstract: Normally ordered robust VSB data are reordered in accordance with a first interleave to produce reordered robust VSB data. The reordered robust VSB data and ATSC data are reordered in accordance with a second interleave to produce normally ordered robust VSB data and reordered ATSC data.
