Appendix G Change/correction
function in a firmware
G.1 Revision J
Here, the item changed / corrected by the firmware revision J is explained.
The firmware revision J is introduced from the product after the serial number
"01800001" of EN311.
Also in EN311 to which the serial number before "01800001" is attached, when the seal
of "J" is stuck on the end of EN311 serial number, a firmware is upgrade ending at
Revision J.
Table G-1 Comparison of a firmware (before Revision J and Revision J)
No
1 When a TCP connection is previously closed from EN311
Revision J If a TCP connection is previously closed from EN311, the socket of EN311
will be in a TIME_WAIT state (state in which the resource remained).
A TIME_WAIT state continues for 15 seconds.
In the Revision J firmware of EN311, when a reset packet (RST) is received
from a partner node in the TIME_WAIT state, EN311 releases the resource of
that socket immediately.
When the resource that remained is released, re-opening of that socket is
attained.
Before
Revision J If a TCP connection is previously closed from EN311, the socket of EN311
will be in a TIME_WAIT state (state in which the resource remained).
A TIME_WAIT state continues for 15 seconds.In the case of the firmware
before Revision I, when a reset packet (RST) is received from a partner node
in the TIME_WAIT state, EN311 does not release the resource of that socket.
For this reason, a socket resource may remain forever by the operation of a
partner node (1).
(1)Operation of a partner node
--SYN, ACK, and a FIN packet are transmitted to the socket with the cycle of
15 or less seconds.
Influence of [ in case a resource is not released ]
--The socket cannot re-open.
--A socket open request carries out error completion in "a LAN controller
driver error."
