[GnomeMeeting-list] whats happening inside jitter buffer?

[nauman ahmed <maniraja_2000 yahoo com>]

i am doing some serious project which includes gnomemeeting as a tool.i am a

bit confused about the

working of jitter buffer.i have two alternative concepts about jitter buffer

here i refer to jitter buffer which is" not adaptive" i.e it size can be changed

manually. ihave the following two concepts

 

1-jitter buffer size(in bytes)is " fixed".Suppose it is 3 times the payload size  .suppose it is set to 100ms at the start

the codec waits for 100ms and then start processing the packets during that any packet

whose sequence no lies within first 3 sequnce nos arrives then

 

1-it is admitted if it arrives before playout time is admitted to the buffer.after finishing

   the buffer the codec again waits for 100ms and the above process is repeated

   again

 

2- it is not admitted to the buffer and simply discarded..after finishing

   the buffer the codec again waits for 100ms and the above process is repeated

   again

                      in both cases any packet whose sequence no doesnot lie

    in the jitter buffer(the packet has arrived much earlier tahn its playout time)

    is buffered in a seperate memory space

 

                                    which of the two is correct? or both are wrong .please

    help me.
