Abstract :

In this talk we seek to characterize the behavior of the Internet in the absence of congestion control. 
More specifically, we assume all sources transmit at their maximum rate and recover from packet 
loss by the use of some ideal erasure coding scheme. We estimate the efficiency of resource 
utilization in terms of the maximum load the network can sustain, accounting for the random 
nature of traffic. Contrary to common belief, there is generally no congestion collapse. Efficiency 
remains higher than 90% in most cases as long as maximum source rates are less than link capacity 
by one or two orders of magnitude. Moreover, a simple fair drop policy enforcing fair sharing at flow 
level is sufficient to guarantee 100% efficiency in all cases.
