The need for realism when simulating network congestion

چکیده
Many researchers use abstract models to simulate network congestion, finding patterns that might foreshadow onset of congestion collapse. We investigate whether such abstract models yield congestion behaviors sufficiently similar to more realistic models. Beginning with an abstract model, we add elements of realism in various combinations, culminating with a high-fidelity simulation. By comparing congestion patterns among combinations, we illustrate congestion spread in abstract models differs from that in realistic models. We identify critical elements of realism needed when simulating congestion. We demonstrate a means to compare congestion patterns among simulations covering diverse configurations. We hope our contributions lead to better understanding of the need for realism when simulating network congestion. Author

Strategies to Overcome Network Congestion in Infrastructure Systems
Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...
متن کاملThe Influence of Realism on Congestion in Network Simulations
Many researchers have used simulation to investigate the spread of congestion in networks. These researchers often find that congestion can be modeled as a percolation process, spreading slowly under increasing load until a critical point. After the critical point, congestion spreads quickly throughout the entire network. The researchers also identify various measureable signals that arise arou...
متن کاملCongestion estimation of router input ports in Network-on-Chip for efficient virtual allocation
Effective and congestion-aware routing is vital to the performance of network-on-chip. The efficient routing algorithm undoubtedly relies on the considered selection strategy. If the routing function returns a number of more than one permissible output ports, a selection function is exploited to choose the best output port to reduce packets latency. In this paper, we introduce a new selection s...
متن کاملHow to define ‘Moral Realism’
Moral realism is the doctrine that some propositions asserting that some action is ‘morally’ good (obligatory, bad, or wrong) are true. This paper examines three different definitions of what it is for an action to be ‘morally’ good (with corresponding definitions for ‘morally’ obligatory, bad, or wrong) which would make moral realism a clear and plausible view. The first defines ‘morally good ...
متن کاملDesign of a Low-Latency Router Based on Virtual Output Queuing and Bypass Channels for Wireless Network-on-Chip
Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...
