TcpNewReno is introduced in RFC 2582. The most recent RFC on this is
the RFC 6582. Since its introduction, Tcp NewReno is the RECOMMENDED
algorithm by the Internet Engineering Task Force. The main difference
between Reno and New Reno is in the Fast retransmit algorithm, in order
to recover more quickly when multiple packet losses occur in a single
window. NewReno introduces the concept of Partial acknowledgments. Since
the intention is to merge fast retransmit and fast recovery into
TcpSocketBase, there isn't the possibility to maintain TcpReno as
separate class. However, its behavior could be introduced again with one
conditional attribute in TcpSocketBase itself.
