Regarding your comment on jitter, FLATLY or more generally, if introducing jitter is likely to complicate operational matters elsewhere in the network [whether this complication manifests within one's own network or in another - to which one is inter-connected] I would be inclined to say this effects the overall performance... I did not mean to take more of your time on this. But, I wanted to merely clarify. Best, Robert. -------
