This paper considers a supply chain where a manufacturer sells its product through a retailer. In such a market, a potential entrant can make a substitute product by imitating the incumbent's product and then sells it to the common market with one of three alternative entry modes: (i) selling through the incumbent's retailer, (ii) selling through another independent retailer, or (iii) selling d...

avila and molina [1] introduced the notion of generalized weak structures which naturally generalize minimal structures, generalized topologies and weak structures and the structures α(g),π(g),σ(g) and β(g). this work is a further investigation of generalized weak structures due to avila and molina. further we introduce the structures ro(g) and rc(g) and study the properties of the structur...

in this note we introduce the notion of weak mccoy rings as a generalization of mccoy rings, and investigate their properties. also we show that, if is a semi-commutative ring, then is weak mccoy if and only if is weak mccoy.

This paper analyzes airport congestion when carriers are nonatomistic, showing how the results of the road-pricing literature are modi ̄ed when the economic agents causing congestion have market power. The analysis shows that when an airport is dominated by a monopolist, either discriminating or nondiscriminating, congestion is fully internalized, provided that a separability assumption on trave...

Active Congestion Control (ACC) uses Active Networking (AN) technology to make feedback congestion control more responsive to network congestion. Current endto-end feedback congestion control systems detect and relieve congestion only at endpoints. ACC includes programs in each data packet that tell routers how to react to congestion without incurring the round trip delay that reduces feedback’...

These problems are related to...

The demand for fast transfer of large volumes of data, and the deployment of the network infrastructures is ever increasing. However, the dominant transport protocol of today, TCP, does not meet this demand because it favors reliability over timeliness and fails to fully utilize the network capacity due to limitations of its conservative congestion control algorithm. The slow response of TCP in...

y Abstract In the context of TCP, several researchers have proposed heuristics to detect or predict congestion in the network. In this paper, the term congestion predictors refers to such heuristics. Past proposals require TCP sender to reduce its window size when congestion is detected or predicted (otherwise, the heuristic may dictate that the sender window be held constant or increased). The...

-In this paper a practically efficient quality of service algorithm is proposed .Here we have a WARSHALS CONGESTION BASED algorithm for congestion path matrix to be retrieved .The algorithm provides the shortest congestion path matrix due to the congestion that is available in between the different vertex .The algorithm provides an alternate solution to the problem available using constant cong...

This paper describes the recent advancements in network congestion control in the Linux kernel. Specifically the paper focuses on the TCP congestion framework, and the implementation of the DCCP protocol stack. Linux has had multiple TCP congestion methods added to it and the subsequent growth of the codebase has made development difficult. As a result a congestion control framework has been in...
