The present disclosure discloses a method and network device for dynamically prioritizing user connections on network. The disclosed system identifies a priority class associated with a client device prior to an initial connection from the client device to a network, and reserves access to a network resource for the client device based on the priority class prior to the initial connection. Specifically, the system evaluates a total capacity of the network resource and an anticipated usage of the network resource by the client device associated with the priority level. Then, the system will reject requests for accessing the network resource received from other client devices prior to the client device associated with the priority level accesses the network resource.

A method and apparatus are provided for transmitting an uplink scheduling request in a mobile communication system. Scheduling request transmission cycles are set according to priorities between a terminal and a radio resource controlling node. The terminal transmits the scheduling request to the radio resource controlling node according to a scheduling request transmission cycle corresponding to a highest priority among priorities corresponding to uplink data or uplink control signals, if the uplink data or the uplink control signals are generated from an upper layer. The terminal receives scheduling information from the radio resource controlling node, and determines whether resource allocation information is included in the scheduling information. The terminal cyclically transmits the scheduling request to the radio resource controlling node in the scheduling request transmission cycle, if the resource allocation information is not included in the scheduling information.

A new device is deployed to an area in which a network is provided. The new device may join the network using a single handshake via a neighboring device that is a member of the network and register with a network management system managing the network. If the network is overloaded or has limited bandwidth remaining, the network may refuse to admit the new device, or if the new device is isolated, may force some devices that are members of the network to leave or migrate from the network to allow the isolated device to join the network.

An asymmetrical and dynamic routing system (ADRS) is provided to enable the dynamic adjustment of the bandwidth capacity of two or more network devices exchanging data. The two or more network devices monitor their current bandwidth demand between themselves and others in a network and a first network device can transmit bandwidth request to a second network device when the first network device reaches transmission bandwidth capacity. Each network device is further configured with additional transmit and receive ports and can be selectively enabled in response to a bandwidth request from other network devices. Each network device is further configured to generate control signals that are sent to optical mirrors to re-direct data signals to or from the one or more enabled additional transmit and receive ports.

According to one aspect, a method that includes some of the teachings of the present subject technology reduces congestion in a communications network. The method includes, inter alia, letting a persistence value be a function of N, even when ASC=0, and also a function of a constant the emergency services access parameter W, such that the persistence value P0(N) ranges between P1(N) and 1 when the emergency services access parameter W ranges from a first value (e.g. 0) to a second value (e.g. 1), where P(N)=2−(N−1) and where N is transmitted in a system information message. A comparator allows a user to access the communications network only if a random/pseudorandom number is less than the persistence value. Other aspects, such as a computer program product, also reduce congestion in a communications network.

Methods and systems for controlling utilization of resources(s) of contention by a plurality of devices of a single or multiple priority classes. A utilization scaling factor is determined for each class for the resource(s) and compared with a threshold value. An apersistence property pattern is then created for each class that includes apersistence property entries corresponding to apersistence update cycles of an apersistence pattern window. Where the scaling factor is in a first range corresponding to low resource loading, the class pattern includes unimpeded entries allowing the devices in a class to attempt to utilize the resource. Otherwise, the class pattern is created with at least one blocking entry that prevents all devices in a class from attempting utilization of the resource during the corresponding apersistence update cycle. An apersistence property pattern entry is then provided from the pattern to the devices in each apersistence update cycle of the apersistence pattern window.

A system and method for ADSL USB bandwidth negotiation are presented. The system comprises a modem that is configured to transfer data between an ADSL line and a USB bus and that is further configured to receive an ADSL line rate setting, submit an isochronous bandwidth request to a computer, reduce the isochronous bandwidth request in response to the availability of isochronous bandwidth, modify the ADSL line rate setting in response to the availability of isochronous bandwidth, and modify the USB bus transfer mode in response to the availability of isochronous bandwidth. The method comprises steps of receiving an ADSL line rate setting, submitting an isochronous bandwidth request to a computer, reducing the isochronous bandwidth request in response to the availability of isochronous bandwidth, modifying the ADSL line rate setting in response to the availability of isochronous bandwidth, and modifying the USB bus transfer mode of the ADSL USB modem in response to the availability of isochronous bandwidth.
摘要:
A mechanism enabling plural queues in a downstream telecommunications network element to be treated as a single, joint queue for purposes of connection-level flow control. A pointer in at least one queue descriptor points to a queue descriptor in which is maintained a set of shared, joint counters. Other flow control elements are maintained individually with respect to each queue descriptor. This mechanism enables flow control elements associated with a single transmitter queue to flow control plural connections terminating in plural queues associated with a single receiver processor.

An Asynchronous Transfer Mode switch and method which facilitate priority arbitration of point-to-point and point-to-multipoint transmission are disclosed. To execute point-to-multipoint operation a bandwidth arbiter maintains a first list of connections and bit vectors indicating designated destination ports. The list maintained by the bandwidth arbiter is then compared to an unassigned output port bit vector to determine matches therebetween at which point-to-multipoint transmission may be made by utilizing instantaneously unused bandwidth within the switch. To execute point-to-point operation each input port maintains a list of connections associated with each output port, and those lists are used in conjunction with output port request information per input port in the bandwidth arbiter to match requests to the unassigned output port bit vector. The bandwidth arbiter may also assign priority to connections in the list.

A switch control module (16) is provided for converting between an internal cell (23) and a first standard asynchronous transfer mode cell (34) and second standard asynchronous transfer mode cell (36). The internal cell (23) includes an internal header (42), payload information (44), and miscellaneous information (46). The first standard asynchronous transfer mode cell (34) includes the internal header (42) and miscellaneous information (46) of the internal cell (23). The second standard asynchronous transfer mode cell (36) includes the payload information (44) of the internal cell (23).
