The drive towards richer, more interactive content places increasingly stringent latency requirements on datacenters. A critical component of meeting these is ensuring that the network responds agilely to congestion, bounding network latency and improving high-percentile flow completion times. We propose a new approach to rapidly detecting and responding to congestion. We introduce FastLane, a ...

This paper describes the development and implementation of a dynamic congestion pricing scheme, augmented with a game-theoretic evolutionary learning model, into a realistic urban highway in Athens, Greece. The model recognizes several important behavioral features related to the response of users to the congestion pricing strategy. Such features include day-to-day as well as within-day adjustm...

Road congestion is an issue that has received growing attention in all big economic activity centers around the world. Congestion seems to be inextricably linked growth, and therefore considered a sign of strong performance. However, at same time, it reflects problem lack matching between demand for supply transport capacity, risking suffocate system. A external costs are not included price tra...

Pricing of roadways opens doors for infrastructure financing, and congestion pricing seeks to address inefficiencies in roadway operations. This paper emphasizes the revenue-generation opportunities and welfare impacts of flat-tolling schemes, standard congestion pricing, and credit-based congestion pricing policies. While most roadway investment decisions focus on travel time savings for exist...

Congestion is a common phenomenon in all major cities of the world. Increased travel time and uncertainty brought about by congestion impacts the efficiency of logistics operations. Recent studies indicate that a significant proportion of commercial vehicle kilometers traveled (VKT) and vehicle hours traveled (VHT) are generated by trip-chains or multi-stop tours. This paper presents research d...

Congestion control with explicit router feedback, such as TCP Quick-Start and XCP, is a promising way to enhance the performance of data transport especially in high-speed networks. When designing such transport protocols, the tradeoff between the granularity of feedback information and additional cost of routers for feedback processing and state keeping should be discussed. However, the feasib...

In a deregulated electricity market, CM is one of the key functions of a System Operator (SO) as congestion threatens system security and may cause rise in electricity price resulting in market inefficiency. Rescheduling generations and demands is an effective tool to relieve congestion. This paper presents a congestion management (CM) algorithm by optimal rescheduling of active powers of gener...

We study a system of replicable (identical) cities with un-priced traffic congestion where each city requires a minimum investment in infrastructure setup costs. We consider alternative planning regimes (or, equivalently, market with profit-maximizing developers), differing from each other according to the public policy for financing the infrastructure. These policies play two roles: 1) providi...
