it is scheduled packet generation and transmission may also be scheduled according to a dithering process when enabled dithering will vary the transmit intervals of all active streams packets associated with a given ip session except a certain stream programmed in a specified entry e g event entry 2048 of 2048 possible entries of the control memory a transmit window of approximately 800 microseconds may be used for scheduling dithered transmission of packets within a 976 microsecond 1024 hz scheduling interval although the time between successive transmissions of a specific stream will be varied the average rate will be executed within each scheduling interval exactly as programmed extensions of the dithering process allow the launching of packets in a burst mode and in modes that have multiple packet transmissions unequally spaced in time but following an overall periodic behavior this transmission pattern is often called u201c n packets in m seconds u201d and is useful to excite certain modes of behavior in packet networks the command and status registers module 412 are configured to store certain configuration information for controlling the operation of the packet interface 320 and modules therein for example the configuration information for the scheduler module 410 may be stored within the command and status registers module 412 additionally a selection bit can be.
