摘要： In one embodiment, one or more indicia of stress are monitored. Based on the one or more indicia of stress, it is determined a stress condition exists. In response to the stress condition, one or more link aggregation actors and partners are caused to enter a grace state for a grace period. While the one or more link aggregation actors and partners are in the grace state, link aggregation formation is paced on a plurality of links by delaying formation of one or more new link aggregation groups on the plurality of links until a hold is released. Upon expiration of the grace period, the grace state is exited.

摘要： Synchronization of traffic multiplexing in link aggregation is described. In an embodiment, a first link aggregator and a second link aggregator are associated with a plurality of links. The first link aggregator maintains an identifier for each link indicating at least a state of enabled or disabled. A synchronized clock is established between the first link aggregator and the second link aggregator. A particular link of the plurality of links is transitioned. Wherein, the transitioning is performed by the first link aggregator sending, to the second link aggregator, a first message identifying a particular time to transition the particular link. The first link aggregator receives, from the second link aggregator, a second message indicating that the particular time is acceptable. In response to a determination that the second message indicates that the particular time is acceptable and that the synchronized clock has reached the particular time, transitioning the link.

摘要： In accordance with the present invention a method of and a system for enhancing image quality of a coded digital video signal representative of at least one frame in a digital video system are provided. The method comprises the steps of creating a usefulness metric identifying a limit to sharpness enhancement to be applied to the coded digital video signal, defining local spatial features in the frame, and identifying a frame type for the frame. The usefulness metric created in the creating step is: UME = 1 - M * ( 1 + q_scale N ) 2 * q_scale num_bits max ⁢ ( q_scale num_bits ) wherein UME is the usefulness metric, q_scale is a quantization scale for a macroblock, num_bits is a number of bits to encode a luminance block, max is a function representing a maximum value for the frame, and M and N are scaling factors. The method further includes the steps of calculating a coding gain of each pixel in the frame based on the local spatial features and the usefulness metric in accordance with the frame type. Finally, the method also includes the steps of applying the coding gain to at least one sharpness enhancement algorithm, and generating an enhanced digital video signal by application of the sharpness enhancement algorithm.

摘要： In one embodiment, a period between periodic transmissions of protocol data units (PDUs) used to form or maintain a link aggregation group is initially set to a fixed value. When a stress condition is detected, the period between periodic transmissions of PDUs is increased from the initial value. When the stress condition is determined to have eased, the period between periodic transmissions of PDUs is reduced back toward the fixed value.
