EVC Definition
AnEVCisalogicalenti tythatprovidesameansforconnectingtwoendpointsintheTotal
Access5000andprovidesapathforEthernetframeswithaparticularVLANIDwithinthe
TotalAccess5000. TheEVCcross‐connectstwoendpointsandprovidesthemechanismby
whichanS‐tag
pathiscreatedinthesystem.TheS‐tagcorrespondstotheVLANID.
IntheTotalAccess5000,customertrafficswitchesthroughoutthesystemviaS‐tags
(outermostVLANtagonanEthernetpacket).Downstreamtrafficentersthesystemthrough

TheMetroEthernetForum(MEF)definesanEVCas“anassociationoftwoormoreUNIs,”
whereaUNIisastandard10/100/1000 Ethernetinterfacethatisthepointofdemarcation
betweenthe CustomerEquipment(CE)andtheMetroEthernetNetwork(MEN)
oftheservice
provider.Insimpleterms,anEVCperformstwofunctions.
• Connectstwoormoresubscribersites(UNIs)enablingthetransferofEthernetservice
frames
•PreventsdatatransferbetweenthesubscribersitesthatarenotpartofthesameEVC
ThiscapabilityenablesanEVCtoprovidedataprivacyandsecurity
similartoaFrame
RelayorATMPermanentVirtualCircuit(PVC).
EachEVCtypicallyhasanassociatedEVCVLANtagwhoseVLANIDisuniqueamongother
EVCsintheMEN.TheEVCVLANtagallowstheEVCtobeidentifiedandseparatedfrom
otherEVCs.
Ataminimum,twoitems
mustbesetupfortheEVC:theMENinterfaceitwilluseandthe
S‐tagitwilluse.
