Abstract
There are disclosed systems and methods for reducing the average delay and the average delay variation of network communication data in a buffer. The buffer comprises a plurality of memory entries, and associated with the buffer is a read point and a write pointer. The buffer has a depth defined as the number of memory entries in the buffer between the memory entry pointed to by the read pointer and the memory entry pointed to by the write pointer. In one embodiment, at least one of the read pointer and the write pointer is initially set to establish the depth of the buffer to be a first value. The variation of the depth of the buffer is then monitored for a predetermined period of time as network communication data flows through the buffer. The depth of the buffer is then reduced based upon this monitoring.
