A few questions

Post by Jakel »

I am a new member to this site and somewhat to broadband (had 640k ADSL for 8 months) and I look around and I am seeing this:
Where is the program that does this test?

____________________________________________
TCP options string = 020405b401010402
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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
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: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = OFF

Time to live left = 119 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

Also, Is all cable Static IP? My Megabit DSL is Dynamic unless I purchase a small pool (8 IPs) for 9 bucks extra.

Cable can be static or dynamic...

Depends on who you buy it from.

And some providers, such as @Home, assign relatively static IPs dynamically. What I mean by that is that they are basically static b/c they don't change frequently, however, they are assigned by the provider's DHCP server.
