In online gaming, lag is a noticeable delay between the action of players and the reaction of the server supporting the video game. The tolerance for lag depends on the type of game. For instance, a strategy game or a turn-based game with a low pace may have a high threshold or even be mostly unaffected by high delays, whereas a twitch gameplay game such as a first-person shooter with a considerably higher pace may require significantly lower delay to be able to provide satisfying gameplay. However, the specific characteristics of the game matter. For example, fast chess is a turn-based game that is fast action and may not tolerate high lag. Also, some twitch games can be designed such that only events that don't impact the outcome of the game introduce lag, allowing for fast local response most of the time.

ActiveUS20180046926A1Easy to understandPrediction is accurateResource allocationEnsemble learningAlgorithmData profiling
A predictive modeling method may include determining a time interval of time-series data; identifying one or more variables of the data as targets; determining a forecast range and a skip range associated with a prediction problem represented by the data; generating training data and testing data from the time-series data; fitting a predictive model to the training data; and testing the fitted model on the testing data. The forecast range may indicate a duration of a period for which values of the targets are to be predicted. The skip range may indicate a temporal lag between the time period corresponding to the data used to make predictions and the time period corresponding to the predictions. The skip range may separate input data subsets representing model inputs from subsets representing model outputs, and separate test data subsets representing model inputs from subsets representing validation data.

In one embodiment, a method of receiving a decoded audio signal that has a transmitted pitch lag is disclosed. The method includes estimating pitch correlations of possible short pitch lags that are smaller than a minimum pitch limitation and have an approximated multiple relationship with the transmitted pitch lag, checking if one of the pitch correlations of the possible short pitch lags is large enough compared to a pitch correlation estimated with the transmitted pitch lag, and selecting a short pitch lag as a corrected pitch lag if a corresponding pitch correlation is large enough. The postprocessing is performed using the corrected pitch lag. In another embodiment, when the existence of irregular harmonics or wrong pitch lag is detected, a coded-excited linear prediction (CELP) postfilter is made more aggressive.

Method for dynamic load balancing of network flows on lag interfaces
ActiveUS20140119193A1Optimize load distributionError preventionTransmission systemsDynamic load balancingData stream
A method is implemented by a network element to improve load sharing for a link aggregation group by redistributing data flows to less congested ports in a set of ports associated with the link aggregation group. The network element receives a data packet in a data flow at an ingress port of the network element. A load sharing process is performed to select an egress port of the network element. A check is whether the selected egress port is congested. A check is made whether a time since a previous data packet in the data flow was received exceeds a threshold value. A less congested egress port is identified in the set of ports. A flow table is updated to bind the data flow to the less congested egress port and the data packet is forwarded to the less congested egress port.
