Abstract: The method performed in the terminal includes generating a random value for wireless channel access, receiving a competitive index indicating a channel competition state from an access point, and determining whether to attempt a wireless channel access based on a comparison result between the random value and the competitive index. Accordingly, in an environment in which a large number of wireless local area network (WLAN) terminals simultaneously attempt the wireless channel access, each terminal voluntarily restricts a wireless connection request in accordance with wireless channel environment information transmitted by an access point, that is, competitive indexes, and therefore wireless channel access competition may be alleviated, thereby improving a wireless connection speed of the terminal and reducing power consumption of the terminal.

Abstract: Systems and methods for analyzing and forecasting network traffic are disclosed. In some implementations, multiple points are received. Each point represents a time value and a network traffic value. For each point in the multiple points, the network traffic value is decomposable into a trend component, a seasonality component, a burst component, and a random error component. A trend equation is generated for calculating the trend component based on the time value. A seasonality equation is generated for calculating the seasonality component based on the time value. A burst equation is generated for calculating the burst component based on the time value. A random error equation is generated for calculating the random error component. A network traffic equation is generated for calculating the network traffic value based on the time value by combining the trend equation, the seasonality equation, the burst equation, and the random error equation.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract: Systems and methods are disclosed for managing congestion in a data network. In a data network, various data flows are transmitted between source and destination nodes. One or more computing devices of the network may be configured to detecting congestion in a first path and provide an indication of the congestion, directly or indirectly, to a destination device. A switch associated with the path is designated for performing rebalancing of the flow based at least in part on a control message generated in response to an instruction received, either directly or indirectly, from a source device. Reassignment of the congested flow to a new path can help alleviate congestion and improve network performance.

Abstract: An example method for intermittent encapsulation of preemptable network traffic at a network node can include receiving a frame at the network node and determining if the frame is a preemptable frame. A preemptable frame is a frame that can be preempted, suspended, interrupted, etc. after transmission begins in order to transmit a preemptive frame. If the frame is a preemptable frame, the method can include determining if the preemptable frame satisfies a selective encapsulation rule. If the preemptable frame does not satisfy the selective encapsulation rule, the method can include transmitting the preemptable frame from the network node without encapsulation. Alternatively, if the preemptable frame satisfies the selective encapsulation rule, the method can include encapsulating and transmitting the preemptable frame from the network node. The preemptable frame can be encapsulated with a preemption header and/or a preemption trailer.

Abstract: A system that provides services to clients may receive and service requests, various ones of which may require different amounts of work. An admission control mechanism may manage requests based on tokens, each of which represents a fixed amount of work. The tokens may be added to a token bucket at rate that is dependent on a target work throughput rate while the number of tokens in the bucket does not exceed its maximum capacity. If at least a pre-determined minimum number of tokens is present in the bucket when a service request is received, it may be serviced. Servicing a request may include deducting an initial number of tokens from the bucket, determining that the amount of work performed in servicing the request is different than that represented by the initially deducted tokens, and deducting additional tokens from or replacing tokens in the bucket to reflect the difference.
