| Summary: | This invention relates in general to data transfer systems and more specifically to an apparatus and method for avoiding jitter and variations in payload size for a voice over packet network.
A system is provided for carrying synchronous voice payloads of variable size across a packet-based network while eliminating network jitter losses. According to the preferred embodiment, two concurrent tasks are implemented. A Voice Packet Processing task receives packetized voice from a packet oriented interface, processes headers of the packet, and builds a receive payload buffer that is managed by means of copying packets to the synchronous interface according to the contents of the payload buffer. The Voice Packet Forwarding task builds a transmit payload buffer for voice samples received from the synchronous interface, builds the necessary protocol headers and forwards the packet to the packet oriented interface. |
