srtt computation correction

[gregbo]

In the section of the TCP page that begins with "The original TCP specification proposed [...]", the smoothed round-trip-time is given as:

srrt=(\alpha \times srtt)+( (1-\alpha) \times rtt)

Please correct it to:

srtt=(\alpha \times srtt)+( (1-\alpha) \times rtt)
