Analyzer screwed up ???

[Rampage2884]

I am using WinXP PRO 2600
Classic Athlon 550
384 ram


For some reason, the " TCP/IP Analzer" keeps giving me an RWIN of 65535, when in I actually I have 513920, well thats what I have in my cablenut adjuster and registry. My IP is given correct but the test is screwed up.

Any suggestions guys.

Why yes, set Tcp1323Opts to 1, REBOOT:)

Thanks Lobo, it worked. I was just wondering. By inputting the 1 value, does that decrease my connection in any way.

BTW, How does this look, you think I should tweak my connection more.


TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Default Settings in Computer doesn't allow you to scale the Rwin, so by setting it to 1, you allow it to be scaled. 2 gives you timestamps but no scaling, and 3 is both. Recommanded value is 1.:)
