Abstract: Web objects, such as media files are sent through an adaptation server which includes a transcoder for adapting forwarded objects according to profiles of the receiving destinations, and a cache memory for caching frequently requested objects, including their adapted versions. The probability of additional requests for the same object before the object expires, is assessed by tracking hits. Only objects having experienced hits in excess of a hit threshold are cached, the hit threshold being adaptively adjusted based on the capacity of the cache, and the space required to store cached media files. Expired objects are collected in a list, and may be periodically ejected from the cache, or when the cache is nearly full.

Abstract: A method, computer program product and electronic device for adjusting a conversion parameter (Cssi) associated with an individual user of a multi-user air link in response to, at least in part, a variation in the transmission quality of the air link. A bandwidth transmission rate (NIRi) is determined for the individual user of the multi-user air link, such that the bandwidth transmission rate (NIRi) is dependant upon the conversion parameter (Cssi) associated with the individual user and a bandwidth distribution parameter (pi) associated with the individual user. The bandwidth transmission rate (NIRi) is compared with a target bandwidth requirement for the individual user of the multi-user air link. The bandwidth distribution parameter (pi) associated with the individual user is adjusted to set the bandwidth transmission rate (NIRi) essentially equal to the target bandwidth requirement.

Abstract: Methods and apparatus, including computer program products, for traffic shaping and scheduling in a network. A computer-implemented method includes receiving a data packet Ln from a network at a rate RN, metering and coloring the packet Ln using two-rate three coloring marking (trTCM), labeling and enqueuing the packet Ln to a scheduler's queue, enqueuing the packet Ln in a deferral queue if the packet Ln is non-conformant and head-of-line (HOL), to delay the packet Ln an amount of time to become conformant, up-dating the conformity parameters upon dequeuing of the packet Ln using its label, determining the conformance of the next HOL packet Ln+1 using its label and the conformity parameters and, if packet Ln+1 is non-conformant, enqueuing the packet Ln+1 in a deferral queue to delay its scheduling an amount of time to become conformant.

Abstract: Methods and apparatus, including computer program products, for H-FDD scheduling in a wireless network. A computer-implemented method includes, in a wireless network including at least a base station and a subscriber station communicating over an air link, scheduling a scheduling frame, the scheduling frame partitioned in N consecutive groups indexed from 1 to N and comprising J air link frames in a downlink (DL) direction over the air link from the base station to the subscriber station and J air link frames in an uplink (UL) direction over the air link from the subscriber station to the base station. The method assigns data from a FDD SS to any group in a DL or UL direction. The method assigns data for H-FDD SS to any group when data flows only in the UL or DL direction and assigns data to a non-overlapping group for the DL direction and the UL direction when data flows in both directions.
