Class Dedup

java.lang.Object
io.github.mahmoudimus.quic.connection.Dedup
public final class Dedup extends Object
A sliding-window detector of duplicate packet numbers, in the style of RFC 4303: a 128-bit field, one bit per packet number below the highest authenticated one. Packet numbers left of the window count as received. Since QUIC never reuses packet numbers, the window only needs to cover reordering.
