In this Comments, two typos in Li and Somani's paper are pointed out. These errors may puzzle readers or even prevent them from drawing the right conclusion. In the second part of this Comments, the authors propose a correction to these errors.
— This paper considers the problem of dynamically establishing dependable connections (D-connections) with specified failure restoration guarantees in wavelength-routed wavelength-division multiplexed (WDM) networks. We call a connection with fault tolerant requirements as a D-connection. We recommend using a pro-active approach to fault tolerance wherein a… (More)
The effects of an attack connection can propagate quickly to different parts of an all-optical transparent network. Such attacks affect the normal traffic and can either cause service degradation or outright service denial. Quick detection and localization of an attack source can avoid losing large amounts of data in an all-optical network. Attack monitors… (More)
In this paper we use game theory to study nodes' behavior in peer-to-peer networks when nodes receive service based on their reputation. Reputation is used as a mechanism to incentivize nodes to share resources and provide services to others. The probability of a node obtaining service is directly proportional to its current reputation, and the only way to… (More)
This paper describes an algorithm for optimally placing a given number of wavelength converters in All-Optical Networks(A0Ns) with arbitrary topologies. We first introduce the simple network model upon which the algorithm is based. We explain how the blocking performance of the network can be obtained when a given number of converters are placed at the… (More)
