.... and experimentation is reported in [Jain et al. 95] Our work, which addresses the important issues of the effects of propagation delays, and time varying available link capacities (owing to high priority stream traffic) is documented in [Abraham and Kumar 97a, Abraham and Kumar 98a, Abraham and Kumar 98b, Abraham 98] Our approach yields algorithms that operate at each switch and use only local information; i.e. no information needs to be explicitly exchanged between between the various switches in order to compute the j values. Each switch only needs to measure the aggregate elastic flow ....

....consists of simply using the admission of a new CBR VBR flow as a trigger for resetting the gain of the algorithm. At such epochs the gain of the algorithm is reset to the initial large value (i.e. a l (k) is increased) We have reported simulations without such resetting of gain in our paper [4]. Large queue length build ups can be avoided in large round trip time (rtt) networks if the gains are increased anticipatively. During the connection setup phase, for a CBR VBR session, a switch is aware of the entry of a session and the amount of bandwidth allocated to it. Thus the stochastic ....
....length thresholds to trigger an increase in the stochastic approximation gain in such situations. The increased gain of the stochastic approximation algorithm coupled with the negative difference between the available capacity and the input flow (see Equation 1) forces a quick reduction of the LCP [4]. Similarly, a decrease in capacity at a remote link may decrease the max min rate of a session, thus decreasing the total flow through another link that this session passes through, and reducing the utilisation of available capacity at this latter link. We suggest the following exponential ....
