How does your network handle packets that are over the limit?

Tor delays sending cells that would exceed its bandwidth limits.
This increases in-process latency, but does not require network retransmits.
But it also does not change the relevant TCP bandwidth delay product.

Most networks drop packets that are over their bandwidth limits.
This increases network retransmits, and triggers a bunch of TCP algorithms
that slow down the connection.
