In this section, simulation results is provided to show how the conditions developed in 3 Stability results for a dumbbell network, 4 Applications to protocol design and parameter settings can be used for network design and applications. In simulations, the single bottleneck link model connecting to N homogeneous sources is used, as depicted by Fig. 1. By using ns2 (NS-2), the simulations are carried out to validate the packet-level implementations and by using Matlab to obtain the flow-level

This paper studies the stability of the primal-dual algorithm for Internet congestion control with round-trip communication delays. The model is formulated as a time-delayed multivariable control system for a general network, and then is studied by using time-delayed control theory. A necessary and sufficient condition is established for a network with a general topology, and then is further discussed for the representative dumbbell network. The stability condition is applied to the design of FAST TCP and adaptive virtual queue (AVQ) scheme as guid...
