Preface
Thevolume,ofwhichyouareinsomedoubtcouldreasonablybecalledabooktobeheldin
humanhands,isacollectionofchapterssamplingthecurrentStateoftheArtofnetwork
and system administration or management. It is written by researchers, for researchers,
educatorsandadvancedpractitioners.
ThefieldofNetworkandSystemAdministrationis(somewouldclaim)stillanemerging
field, one that bridges disciplines, and challenges the traditional boundaries of computer
science.Itforcesustoconfrontissueslikepartialpredictabilityandpartialreliabilitythat
aremorecommonlyassociatedwithengineeringdisciplinesinanuncertainenvironment.
It does so because human–computer networks are complex and uncertain environments.
Inotherwords,itrediscoversthelessonthatotherscienceshavealreadymadepeacewith:
thatapproximationistheonlyrealisticapproachtoitsdifficulties.
Whatever the novelty of the field, there is already a large body of knowledge about it,
