    SpeedGuide.net TCP/IP Analyzer
    TCP properties for IP = 24.162.177.201 ()
    Note: Read the FAQ if the above is not your IP address.
    Browser/OS = Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90)

    TCP options string = 020405b40103030401010402

    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) = 554800
    RWIN Scaling (RFC1323) = 4 bits
    Unscaled Receive Window = 34675
    RWIN is 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: 22192 kbps (2774 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 8876.8 kbps (1109.6 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 45 hops
    TTL value is ok.

    Timestamps (RFC1323) = OFF

    Selective Acknowledgements (RFC2018) = ON

    IP type of service field (RFC1349)= 00000000




    21654 connections tested since 03.10.2001.
    Analyzer version: Beta 0.99
