Method and apparatus for tolerating scheduling latency and achieving time alignment for transmit and receive signals in high-speed modems implemented on host processors

摘要

The preferred embodiment of the present invention provides a method and apparatus for dealing with scheduling latency in high-speed modems (100) implemented on host processors (101). With the present invention, high scheduling latency of the host operating system (135) is tolerated without incurring large end-to-end transmission delay. In addition, time alignment between downstream and upstream signals (175, 180) is achieved even though the scheduling delay may be large and varying.
