The Price of Stability for Network Design With Fair Cost Allocation

Network design is a fundamental problem for which it is important to understand the effects of strategic behavior. Given a collection of self-interested agents who want to form a network connecting certain endpoints, the set of stable solutions - the Nash equilibria - may look quite different from the centrally...

Routing Stability in Static Wireless Mesh Networks

Considerable research has focused on the design of routing protocols for wireless multi-hop networks. Yet, very little is understood about the stability of routes in such networks. This understanding is important in the design of wireless routing protocols, and in network planning and management. This paper presents results from the...

A New TCP Congestion Control With Empty Queues and Scalable Stability

This paper describes a new congestion avoidance system designed to maintain dynamic stability on networks of arbitrary delay, capacity, and topology. This is motivated by recent work showing the limited stability margins of TCP Reno/RED as delay or network capacity scale up. Based on earlier work establishing mathematical requirements for...

Stability Analysis of RED Gateway With Multiple TCP Reno Connections

It has been observed that a bottleneck Random Early Detection RED gateway becomes oscillatory when regulating a flow in multiple TCP connections. The stability boundary of the TCP-RED system depends on various network parameters, making the adjustment of the RED gateway a difficult task. Based on a fluid-flow model, the...

On the Stability of Networks Operating TCP-Like Congestion Control

This paper derives decentralized and scalable stability conditions for a fluid approximation of a class of Internet-like communications networks operating a modified form of TCP-like congestion control. The network consists of an arbitrary interconnection of sources and links with heterogeneous propagation delays. The model here allows for arbitrary concave utility...

Dynamic Analysis of Congested TCP Networks

The objective of this paper is to study the small-signal stability of congested TCP networks. The starting point for this analysis is a fluid model describing the interaction of TCP-controlled traffic with congested routers. Assuming integral action in the active queue management scheme, the network's equilibrium point is computed about...

Long-term planning in a short-term world: The stability stance

A company's strategic stance dictates its project time horizons--which, in turn, have a major impact on how the IT organization functions. In growth stance, businesses will have extended horizons, with long-term projects sometimes stretching over five years. By contrast, the stability stance demands a far more constricted horizon. Stability-oriented companies,...

(Gallery: $60 router + DD-WRT = high-end wireless router)

Software stability?The screen shots show excellent functionality, although I didn't see syslog logging in there perhaps on a screen not captured. The main issue aside from warranty I can see would be stability of DD-WRT "firmware". Anyone any experience with it?

Stability Analysis of Some Classes of TCP/AQM Networks

The local stability analysis of some classes of nonlinear time-delay systems, encountered as fluid flow models for TCP/AQM networks, is addressed. Necessary and sufficient conditions for the asymptotic stability of the linearized models are obtained. Nonlinear stability conditions are derived using a Lyapunov-Krasovskii functional approach. The analysis of fluid flow...

Linear Stability Analysis of FAST TCP Using a New Accurate Link Model

A link model which captures the queue dynamics when congestion windows of TCP sources change was recently proposed. By considering both the self-clocking and the link integrator effects, the model is a generalization of the known extreme cases and is more accurate in general. This paper applies this model to...
