TCP options string = 020405b401010402 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) = 65535 RWIN Scaling (RFC1323) = 0 bits Unscaled TCP Receive Window = 65535 Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix. For optimum performance, consider changing RWIN to a multiple of MSS. Other RWIN values 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 (Note this is not a speed test): Your TCP Window limits you to: 2621 kbps (328 KBytes/s) @ 200ms Your TCP Window limits you to: 1049 kbps (131 KBytes/s) @ 500ms MTU Discovery (RFC1191) = OFF Time to live left = 111 hops TTL value is ok. Timestamps (RFC1323) = OFF Selective Acknowledgements (RFC2018) = ON IP type of service field (RFC1349) = 00000000 (0)
