In watching the [streams of the IETF QUIC sessions](https://www.youtube.com/watch?v=9xDS27UBi4U) there's a lot of discussion around "epoch", but this term is not defined in any of the quic draft documents, and is only mentioned (as "recovery epoch" and "congestion epoch") in the sample code in the -recovery appendices.

It is defined and discussed in the [DTLS RFC](https://tools.ietf.org/html/rfc4347), however.

I'm not sure if mention of "epoch" should be purged or expanded, but it struck me as unclear currently.
