Fault-tolerant routing protocols in modern interconnection networks rely heavily on the network flow control mechanisms used. Optimistic flow control mechanisms such as wormhole routing (WR) realize very good performance, but are prone to deadlock in the presence of faults. Conservative flow

/delay. In this work, we propose token flow control (TFC), a flow control mechanism in which nodes in the network send out tokens in their local neighborhood to communicate information about their available resources. These tokens are then used in both routing and flow control: to choose less congested paths

Another version of TCP called TCP Vegas has been proposed and studied in the literature. It can achieve better performance than the current TCP Reno. In our previous studies, steady-state behavior of a windowbased flow control mechanism based on TCP Vegas has been analyzed for a simple network

We propose an optimization approach to flow control where the objective is to maximize the aggregate source utility over their transmission rates. We view network links and sources as processors of a distributed computation system to solve the dual problem using gradient projection algorithm

models: a decentralized label model, label polymorphism, run-time label checking, and automatic label inference. JFlow also supports many language features that have never been integrated successfully with static information flow control, including objects, subclassing, dynamic type tests, access control

This paper investigates mechanisms that guarantee secure information flow in a computer system. These mechanisms are examined within a mathematical framework suitable for formulating the requirements of secure information flow among security classes. The central component of the model is a lattice

This paper presents a certification mechanism for verifying the secure flow of information through a program. Because it exploits the properties of a lattice structure among security classes, the procedure is sufficiently simple that it can easily be included in the analysis phase of most existing

through the attacker's observations of system output; this policy regulates information flow.

This paper studies the flows of funds into and out of equity mutual funds. Consumers base their fund purchase decisions on prior performance information, but do so asymmetrically, investing disproportionately more in funds that performed very well the prior period. Search costs seem

Graduate Recently, a new version of the TCP mechanism, called TCP Vegas, is proposed, and has potential to achieve better performance than current mechanisms such as TCP Tahoe and Reno. This paper considers a windowbased flow control mechanism based on a slightly modified congestion avoidance
