the scheme suffers a packet loss and is forced to decrease the rate the value of u03b1 is reset to the value shown in equation 4 in practice this exponential increase of u03b1 must stop at some time which is when the increase step f i x i becomes more than a certain percentage of capacity c i e c m where m is some constant greater than 1 in other words u03b1 is doubled while this condition holds wherein c is the capacity of the bottleneck link and m is constant typically in the range of 10 u2013 100 in other words the increase function f i will be doubled with each congestion cycle i e once per rtt until it reaches a certain value in the range between 1 and 10 of capacity c after reaching a certain percentage 1 u2013 10 of the bandwidth capacity the increase function f l will be constant i e f x i c m this constitutes a linear probing for new bandwidth and is equivalent to using increase power k 0 this condition is enforced by using the following computation of u03b1 for all increase cycles except the one following congestion during the first increase cycle after congestion the schemes uses equation 4 u03b1 i 1 min 2 u03b1 i cx i k m the second improvement is applied to the decrease cycle of a scheme with constant packet loss scalability to expedite the backoff i e rate reduction during congestion the second proposed method doubles the value of u03b2 after each decrease cycle note that once congestion is relieved the value of u03b2 is reset to its default value in equation 4 the same rules apply to doubling the value of u03b2 u2014 do not allow.
