Here is an excerpt of what Mike Crane, author of the Cisco CID Exam Certification Guide from Cisco Press, is saying in his own words in this book, page 538:
"Another adjustment is to increase the TCP window size to allow more outstanding requests. This command can also minimize packet fragmentation fragmentation, because larger packets means fewer smaller ones" To me this make sense, because when you decrease the TCP window size you will need more IP packets to carry the TCP Traffic. Here the packet fragmentation occurs due to the TCP window size limit and not due to the IP MTU size limit What you think guys -- watch your phone call records on the web at: http://www.freedomstar.com/sh1885969 | ""Circusnuts"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > John- I believe you've let this term confuse you.
