A rate adaptation system includes a barrel shift slot register and a rate adaptation register. The barrel shift slot register includes a plurality of slots with one of a valid read request or a dummy read request. A rate adaptation register is configured to sequentially cycle through the slots of the barrel shift register in response to a clock providing valid read requests to a FIFO buffer and to skip provision of valid read requests for clock cycles of the first clock associated with slots that include dummy read requests. The rate adaption register may also receive data blocks from the FIFO buffer and provide those data blocks to another FIFO buffer.

The creation of an effective circuit between a sender device and a receiver device over the packet-switched network is described herein. To establish the effective circuit, the sender device sends a request to the receiver device through the packet-switched network. The request is associated with a bandwidth reservation from the receiver device for reception of a message from the sender device. The receiver device receives multiple requests from multiple sender devices and reserves bandwidth for at least one of the sender devices. The receiver device then sends a response to the at least one sender device providing clearance to send the message to the receiver device using the reserved bandwidth, the request and response establishing the effective circuit. The receiver device may also decline the requests of the other sender devices, causing the other sender devices to send other requests to other receiver devices.

Embodiments of the present invention disclose a data scheduling method and a data scheduling device, which is configured to: receive channel quality information sent by a first terminal; calculate a current instantaneous scheduling rate of the first terminal on a first component carrier by using the channel quality information; acquire an average scheduling rate of the first terminal on the first component carrier; calculate a scheduling priority of the first terminal on the first component carrier by using the instantaneous scheduling rate and the average scheduling rate; and allocate a physical resource of the first component carrier to the first terminal. In this way, a multi-carrier terminal is enabled to obtain a stable high rate, differentiation between terminals is achieved.

Systems and methods are provided for identifying an available infrastructure network topology consisting of a set of available network links and a set of available network nodes of a communication network. In the systems and methods, a network node of the communication network is operative to transmit a learning schedule to a plurality of network nodes interconnected by a set of network links of the communication network. The network node receives from each of the plurality of network nodes a communication node record including network performance observations observed by that network node based on the learning schedule transmitted to that network node. Based on the received communication node records, the network node identifies a set of available network links from the set of network links and the set of available network nodes corresponding to the set of available network links.

Systems and methods for network bandwidth, buffers and timing management using hybrid scheduling of traffic with different priorities and guarantees are provided. In certain embodiments, a method of managing network scheduling and configuration comprises, for each transmitting end station, reserving one exclusive buffer for each virtual link to be transmitted from the transmitting end station; for each receiving end station, reserving exclusive buffers for each virtual link to be received at the receiving end station; and for each switch, reserving a exclusive buffer for each virtual link to be received at an input port of the switch. The method further comprises determining if each respective transmitting end station, receiving end station, and switch has sufficient capability to support the reserved buffers; and reporting buffer infeasibility if each respective transmitting end station, receiving end station, and switch does not have sufficient capability to support the reserved buffers.

The present invention relates to systems and methods for network labeling in order to enhance real time data transfers. A network for a real time data transfer is identified and predictive models for network performance are compared against to determine if the network is suitable for the data transfer. If so, then the real time data transfer may be completed as expected. However, if the network is predicted to be unsuitable for transmission an alternate means for connection may be suggested. The alternate suggestion may include delaying the data transfer until the network is expected to be in better conditions, connecting to another access point in the network, or switching to another network entirely. During the data transfer, the quality of the network is monitored in order to update the predictive models for the network's quality. Identifiers for the network may be utilized to keep track of the networks. Network signal strength, signal pollution and time may also be tracked in order to identify patterns in the network's performance.

Provided are a data transmission control method and device and a non-transitory computer-readable medium. The data transmission control method includes: determining a multiple and a remainder according to a total data size of to-be-transmitted data and a set byte size, where the multiple is equal to a quotient obtained by dividing the total data size by the set byte size, and the remainder is equal to a remainder obtained by dividing the total data size by the set byte size; sequentially transmitting data whose size is the set byte size multiplied by the multiple in the to-be-transmitted data by transmitting data of the set byte size each time; and in response to the remainder being not zero, transmitting remaining data whose size is the remainder in the to-be-transmitted data.

[Problem] When a resource reserved in a resource sharing system become unavailable, the reservation is efficiently reset.

[Solution] A resource sharing system 10 shares resources 30 with a plurality of users 20 (user terminals). A resource reservation management device 42 includes: a reservation setting unit 402 that accepts a reservation request for the resource 30 from the user 20, and sets a reservation on a predetermined resource 30 in the resource sharing system 10; and a reservation changing unit 404 that resets the reservation to another resource 30 in the resource sharing system 10 in case the predetermined reserved resource 30 becomes unavailable. if the other resource 30 has insufficient resource capacity, the reservation changing unit 404 resets the reservation to the other resource 30 based on a reservation changing policy defining which reservation is preferentially reset out of the reservation to be reset.

Apparatus and methods of wireless communications include, at a receiving node, receiving timing information corresponding to a traffic class identifier. The timing information being associated with a time interval for communicating data of a traffic class corresponding to the traffic class identifier. Aspects include receiving traffic data pertaining to the traffic class, determining that the traffic data was transmitted or is received outside the time interval, and then buffering the traffic data. Additionally, aspects include forwarding the traffic data in response to a next occurrence of the time interval. A transmitting node may be configured with complimentary functions.
