Jitter buffer for a circuit emulation service over an internet protocol network
View Patent ↗A jitter buffer receives a plurality of data packets comprising a circuit emulation service over internet protocol (CESIP), buffers the plurality of data packets, and plays data from the plurality of data packets at a constant bit rate corresponding to the CESIP.
1. A method comprising:
adjusting the first constant bit rate based on a level of buffered data packets of the first plurality of data packets;
receiving a first plurality of data packets comprising a first circuit emulation service over internet protocol;
buffering the first plurality of data packets; and
playing data from the first plurality of data packets at a first constant bit rate corresponding to the first circuit emulation service over internet protocol, wherein adjusting the first constant bit rate comprises a
increasing the first constant bit rate if the level of buffered data packets exceeds a tolerance range; and
decreasing the first constant bit rate if the level of buffered data packets drops below the tolerance range.
2. The method of claim 1 , wherein the tolerance range is based on a clock rate variation of a time division multiplexing circuit being emulated by the first circuit emulation service over internet protocol.
