EthernetisahighlysuccessfulLAN(LocalAreaNetwork)standardwithsupportfromawidearrayofsilicon,board,andsoftwarevendors.OriginallydevelopedbyaconsortiumconsistingofDigitalEquipmentCorporation,Intel,andXerox(“DIX”)itwaseventuallystandardizedin1983.Higherspeedsofoperationandothernewcapabilitieshavebeendefinedandincorporatedintothestandardovertheyears.IEEE802.3anditsamendmentsareapprovedasnationalstandardsbyANSI,andinternationalstandardsbyISO,althoughtheseapprovalswilllagfromIEEEStandardsAssociationapproval.TheinternationalstandardsarepublishedasISO/IEC8802-3.TheEthernetstandardsreferredtobyPICMG3.1arelistedinSection

FibreChannelhasbecomeaverypopularstandardfortheconnectionofdiskmediastoragesystemswithprocessorstoformSANs(StorageAreaNetworks).IthasbeenincorporatedintoPICMG3.1toallowthedevelopmentofchassisunitswithmassstorageinadditiontoprocessingandswitching.

Itisexpectedthat10GigabitEthernet,whenfullydeveloped,willincludethecapabilityofintegratingboththeSANandtheLANfunction.PICMG3.1supports10GigabitEthernetviaAdvancedTCA?channelsusingXAUIsignaling.

AsimilararchitecturetoPICMG3.1(forEthernetonly)wasdevelopedbythePICMG2.16sub-committee,whoseRevision1.0standardwaspublishedonSeptember5,2001.ManyofthemembersofthePICMG2.16sub-committeearenowparticipatinginthePICMG3.1sub-committee.
