Lecture Notes in Computer Science Performance Evaluation of Complex Systems: Techniques and Tools: Performance 2002. Tutorial Lectures, Book 2459, (Paperback)

Thefastevolutionandtheincreasedpervasivenessofcomputersandcom- nicationnetworkshaveledtothedevelopmentofalargevarietyofcomplex applicationsandserviceswhichhavebecomeanintegralpartofourdailylives. Modernsocietywidelyreliesoninformationtechnologies. Hence, theQuality ofService, thatis, thee?ciency, availability, reliability, andsecurityofthese technologies, isanessentialrequirementfortheproperfunctioningofmodern society. Inthisscenario, performanceevaluationplaysacentralrole. Performance evaluationhastoassessandpredicttheperformanceofhardwareandsoftware systems, andtoidentifyandpreventtheircurrentandfutureperformancebo- lenecks. Inthepastthirtyyears, manyperformanceevaluationtechniquesandtools havebeendevelopedandsuccessfullyappliedinstudiesdealingwiththec- ?gurationandcapacityplanningofexistingsystemsandwiththedesignand developmentofnewsystems. Recently, performanceevaluationtechniqueshave evolvedtocopewiththeincreasedcomplexityofthecurrentsystemsandtheir workloads. Manyoftheclassicaltechniqueshavebeenrevisitedinlightofthe recenttechnologicaladvances, andnoveltechniques, methods, andtoolshave beendeveloped. Thisbookisorganizedaroundasetofsurveypaperswhichprovideac- prehensiveoverviewofthetheories, techniques, andtoolsforperformanceand reliabilityevaluationofcurrentandnewemergingtechnologies. Thepapers, by leadinginternationalexpertsinthe?eldofperformanceevaluation, arebasedon thetutorialspresentedattheIFIPWG7. 3InternationalSymposiumonCom- terModeling, Measurement, andEvaluation(Performance2002)heldinRome onSeptember23-27,2002. Thepapersaddressthestateoftheartofthetheoreticalandmethodological advancesintheareaofperformanceandreliabilityevaluationaswellasnew perspectivesinthemajorapplicationdomains. Abroadspectrumoftopicsis coveredinthisbook. Modelingandveri?cationformalisms, solutionmethods, workloadcharacterization, andbenchmarkingareaddressedfromametho- logicalpointofview. Applicationsofperformanceandreliabilitytechniquesto variousdomains, suchas, hardwareandsoftwarearchitectures, wiredand- relessnetworks, Gridenvironments, Webservices, real-timevoiceandvideo applications, arealsoexamined. Thisbookisintendedtoserveasareferenceforstudents, scientists, and- gineersworkingintheareasofperformanceandreliabilityevaluation, hardware andsoftwaredesign, andcapacityplanning.
