PPPoA Tiscali 4000/320



TCP options string = 020405b40103030301010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default TCP Receive Window (RWIN) = 513920
RWIN Scaling (RFC1323) = 3 bits (scale factor of 6)
Unscaled TCP Receive Window = 64240

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8) <-- current value
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 20556.8 kbps (2569.6 KBytes/s) @ 200ms
Your TCP Window limits you to: 8222.72 kbps (1027.84 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 55 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)




Che valore metto in MTU ed Rwin? Devo modificare altri valori oltre a questi 2? Grazie
