I think that latency has more to do with your transmission medium.
And I think that jitter has more to do with contention.

I think that the design of TCP more has to do with using the network
efficiently and with operating reliably in the presence of congestion.

I'm not sure how TCP is designed to avoid intoducing latency.  The
protocol tries to operate reliably but doesn't really make any
guarantees that the bytestream will make it to the destination by a
certain time.

Thanks for reminding me about tc!
