    摘要: Carrier sensing and power control, or trade-off among two or more communication parameters, can provide relative improvement in throughput. A sensing threshold or transmission power are varied, thus altering a sensing range and a transmission quality, thus maximizing a feasible transmission rate. Transmission power and rate are collectively altered to find a best throughput rate. A transmission rate can incremented after successful transmission and decremented after failed transmission, the described increment possibly being less than the described decrement. Thus, pairs of transmissions where one fails and one succeeds decrease the net transmission rate. Smaller increments, with larger decrements, cause increases to increase throughput without degrading quality, while causing decreases to restore transmission quality if an increase does degrade transmission quality.

    摘要: A method for designing a telecom network includes retrieving data corresponding to a plurality of network node locations, a plurality of subscriber locations and other relevant information such as associated street blocks and distance values. Each network node location and subscriber location combination having a distance value therebetween greater than a maximum distance is initially eliminated. Thereafter, each network node location and subscriber location combination is assigned a priority value, based on constraints such as the proximity between their associated street blocks and/or the maximum capacity of each network node location. The total sum of priority values and total number of subscriber locations are then calculated for those sets of network node locations and corresponding subscriber locations that are selected by the algorithm. A final set of network node locations and assigned subscriber locations is identified by determining the set having the lowest total sum of priority values, which minimizes the street crossings in the design, and the highest number of subscriber locations.

    摘要: A system, apparatus, and method for providing secure loss recovery for packet loss due to bit errors and other non-congestion-related packet loss occurring over the communication link. An intermediary node in a network between a sending node and a receiving node identifies packet loss due to bit errors (PLB), or other non-congestion-based packet loss, over a network connection between the sending module and the network node. A loss notification signal is sent from the network node to the sending module in response to identification of the non-congestion-based packet loss. The PLB is verified at the sending module. A first loss recovery procedure is performed, different from a second loss recovery procedure associated with congestion-based packet loss, if the PLB is verified at the sending module.

    摘要: The method disclosed herein restricts overflooding due to address registration of an unstable asynchronous transfer mode (ATM) terminal through an interim local management interface (ILMI) protocol in an asynchronous transfer mode switch. The asynchronous transfer mode switch registers an address of the asynchronous transfer mode terminal using the interim local management interface protocol, and then determines whether the asynchronous transfer mode terminal is stable or not stable. When the asynchronous transfer mode terminal is not stable, the asynchronous transfer mode switch defers application of a private network-to-network interface (PNNI) until the asynchronous transfer mode terminal becomes stable.

    摘要: A route switching method for switching a route in a core network that accommodates service networks including user node apparatuses by use of a server storing path information that includes, in every time frame, a route for a working path and a route for a backup path to be switched over from the working path, both of the working path and the backup path established between two boundary node apparatuses each of which is located on a boundary between the service network and the core network. The server calculates, in response to the connection request from the user node apparatus, a route for a working path and a route for a backup path, and requests the boundary node apparatus to establish this working path. The server can send the route for the backup path to the boundary node apparatus before a failure occurs in the core network. The boundary node apparatus establishes the working path in response to the establishment request for establishing the working path from the server, and can perform a quick recovery by switching over the working path to the backup path when a failure occurs in the core network.
