Queue Dynamics of RED Gateways under Large Number of TCP Flows
(2001)
We consider a stochastic model of a RED gateway under competing TCP-likesources sharing the capacity. As the number of competing flows becomes large, the queue behavior of RED can be described by a two-dimensional recursion. ...
Characterization of General TCP Traffic under a Large Number of Flows Regime
(2002)
Short-lived TCP traffic (e.g., web mice) composes the majority of the current Internet traffic. Accurate traffic modeling of a large number of short-lived TCP flows is extremely difficult due to (i) the interaction between ...
Dynamic Resource Allocation of GPS Queues with Leaky Buckets
(2003)
We study the problem of dynamic resource allocation of a GPS server with two traffic classes when the leaky bucket scheme is employed as a traffic policing mechanism. Three popular input traffic models -- independent Poisson ...
Dynamics of Random Early Detection Gateway Under A Large Number of TCP Flows
(2004)
While active queue management (AQM) mechanisms such as Random Early Detection (RED) are widely deployed in the Internet, they are rarely utilized or otherwise poorly configured. The problem stems from a lack of a tractable ...
Limiting Model of ECN/RED under a Large Number of Heterogeneous TCP Flows
(2003)
Accurate modeling of a large number of heterogeneous TCP flows is important for the understanding and control of Internet traffic. Difficulties in deriving such models arise due to the interaction between different protocol ...
On the Fairness of the Reverse-Link MAC Layer in cdma2000 1xEV-DO
(2004)
We investigate the fairness of two reverse-link MAC algorithms in cdma2000 1xEV-DO High Rate Packet Data systems. Following the framework proposed by Kelly for Internet congestion-control, we formulate a utility maximization ...
On the behavior of ECN/RED gateways under a large number of TCP flows: Limit theorems
(2005)
We consider a stochastic model of an ECN/RED gateway with competing TCP sources sharing the capacity. As the number of competing flows becomes large, the asymptotic queue behavior at the gateway can be described by a simple ...
TCP Traffic Modeling via Limit Theorems
(2002)
Traditional TCP traffic modeling has focused on "micro-scale"modeling of TCP, i.e., detailed modeling of a single TCP flow. While micro-scale models of TCP are suitable for understanding the precise behavior of individual ...
Asymptotic Behavior of Heterogeneous TCP Flows and RED Gateway
(2003)
We introduce a stochastic model of a bottleneck ECN/RED gateway under a large number of heterogeneous TCP flows, ie flows with diverse round-trips and session dynamics. We investigate the asymptotic behavior of the system ...
