    1010
     11  The I2P network is still relatively small but is growing quickly. How about a prediction or sensitivity analysis for a network 10X, 100X larger?

    2224 1) Timetable of 0.8.4 release:
    23 Released March 2, installed in 25% of network by ~March 4, 50% by ~March 6, 75% by ~March 14 (source http://stats.i2p.to/cgi-bin/total_routers_3month.cgi )
     25   Released March 2, installed in 25% of network by ~March 4, 50% by ~March 6, 75% by ~March 14 (source http://stats.i2p.to/cgi-bin/total_routers_3month.cgi )
    2426
    2527 2) Relevant changes in 0.8.4 release:
    2628    a) Prevent tunnel-building DOS by a single source. This was done in reaction to the attack.
     29
    2730    b) Penalize peers more due to tunnel rejections. This did not change the time constants of the capacity formulas, just changed (a + r) to (a + 2r) in the denominator of the forumla in section A.1. However it may have had the effect of reacting faster to a DOS attack. This change was not made in reaction to the attack, but was previously planned and is part of a strategy to spread the traffic across more peers in the network and adjust the forumla in response to network conditions that have changed markedly in the past two years.
