Definition of:PPS  (Packets Per Second) The measurement of
activity in a packet-switched network. For example, local area
networks (LANs) and the Internet break all data, no matter what
their content, into individual packets before transmitting them.
Each packet contains source and destination addresses, and
routers are rated for performance by the number of packets they
can forward in one second based on the destination address. See
packet switching, router and traffic.
