An On-Off Source Model for Improved Buffer Statistics Modeling in TCP Fluid Approximation Models.

An On-Off Source Model for Improved Buffer Statistics Modeling in TCP Fluid Approximation Models.

We propose using an on-off fluid source model for queuing statistics under TCP. This model was originally introduced to model queuing statistics of ATM multiplexers by D.Anick, D.Mitra and M.M.Sondhi. A good approximation for packet loss probability is
