In the field of Quality-of-Service (QoS) management for adaptive real-time services running on mobile devices which support different access technologies in dynamic wireless Internet Protocol (IP) networks, the connectivity of the applied nodes is unpredictable time-varying. In this context, a QoS management unit (304) is proposed that allows adaptive applications with real-time requirements in typical mobile wireless scenarios—e.g. a radio link with a changing transmission quality and handover procedures (2900)—to adaptively and responsively react to a time-varying network topology and different radio link characteristics.

Disclosed is a method and apparatus to continuously transmit high bandwidth, real-time data, on a communications network (e.g., wired, wireless, and a combination of wired and wireless segments). A control computing device uses user or application requirements to dynamically adjust the throughput of the system to match the bandwidth of the communications network being used, so that data latency is minimized. An operator can visualize the instantaneous characteristic of the link and, if necessary, make a tradeoff between the latency and resolution of the data to help maintain the real-time nature of the system and better utilize the available network resources. Automated control strategies have also been implemented into the system to enable dynamic adjustments of the system throughput to minimize latency while maximizing data resolution. Several applications have been cited in which latency minimization techniques can be employed for enhanced dynamic performance.

Methods, systems and apparatus for reducing apparent latency in content-delivery networks are provided. Sources multicast certain ‘preview multicast streams’ to multiple subscribers. These preview multicast streams provide pre-recorded content of multicast streams.

Thereafter, the pre-recorded content is played during the setup of the new multicast distribution tree to minimize latency. Once the distribution tree is setup, live content of the desired multicast stream is made available to the subscriber.

A latency reduction method for read operations of an array of N solid-state storage devices having n solid-state storage devices for data storage and p solid-state storage devices for storing parity data is provided. Utilizing the parity generation engine fault tolerance for a loss of valid data from at least two of the N solid-state storage devices, the integrity of the data is determined when N−1 of the solid-state storage devices have completed executing a read command. If the data is determined to be valid, the missing data of the Nth solid-state storage device is reconstructed and the data transmitted to the requesting processor. By that arrangement the time necessary for the Nth solid-state storage device to complete execution of the read command is saved, thereby improving the performance of the solid-state memory system.

Packet processing can be broken up into different phases, each phase having a different tag dependent on ordering and synchronization constraints for the phase. A tag switch operation initiated by a core switches a tag dependent on the phase. A dedicated tag switch bus minimizes latency for the tag switch operation.

A method for multimedia playback and transmission to wireless clients is described. A host webserver transcodes a live digital or analog audio-visual or audio broadcast signal and splits the input stream into small multimedia objects of an efficient compression such as MPEG4 / AAC, and then immediately deploys the objects to distributed content servers for a geographically dispersed population of wireless clients.

The applet uses novel video and audio decoding optimizations which can be generically applied to many digital video and audio codecs, and specifically decodes Simple Profile MPEG4 video and Low Complexity AAC audio.

In a method for improving the transmission efficiency in a communication system with a layered protocol stack, data packets are processed on an upper protocol layer. Data packets are forwarded to a lower protocol layer for transmission and the transmission is performed with variable channel access delays. The upper protocol layer is notified by the lower protocol layer when a transmission is started to allow a synchronization of timers in the upper protocol layer. If a layer performs a scheduling of data packets for the transmission, a rescheduling is performed alternatively or in addition during a channel access delay. Devices and software programs embodying the invention are also described.

A technique is disclosed involves a station (e.g., an IEEE 802.11 station, etc.) requesting that one or more frames be transmitted from an access point to the station. The station might have been in power save mode during Bluetooth operation for the purpose of causing the access point to queue frames that are intended for the station. The station making the request is collocated with the Bluetooth station or is, in fact, a single station that supports two protocols (i.e., has two parts), and is able to determine the regular timing of the Bluetooth synchronous connected oriented (SCO) packet transmissions. The requests to the access point for IEEE 802.11 frames are timed to cause the access point response frames to fall between the Bluetooth messages, thus managing potential interference.

In this manner, some embodiments perform a more efficient and seamless handover from the licensed wireless network as the delay resulting from the handover is minimized by performing the channel activation procedure prior to the handover.
