1) In short Fast Link Pulse (FLP) is used to perform autonegotiation on
twisted pair
media. For details see:
See:
http://cisco.com/warp/public/473/46.html
2) TCP slow start is flow control mechanism employed by the sender. This
allows the
sender to probe the maximum window size it may use for transmisson without
significantly
impacting throughput. It starts by transmitting data in one window chunks of
a size
specified by the lowest MSS advertised by each host. The transmitter calls
this window
the congestion window (cwnd). For each ACK received the congestion window is
increase by
one. Only cwnd segments may be outstanding at any one time. This increases
until packets
begin to be dropped. This results in an exponential growth of the number of
segments
that will be transmitted before recieving an ACK.
See:
- TCP/IP illustrated by W. Richard Stevens
- "Congestion Avoidance and Control," V. Jacobson, ACM SIGCOMM-88, August
1988.
3) The CSU/DSU should go into loopback mode and instead of passing data
through its
framer and on to the DTE it should send the data back to the network. This
is useful for
circuit testing.
