Stream VMCI Sockets
TheflowchartinFigure 3‐1showshowtoestablishconnection‐orientedsocketsontheserverandclient.
Figure 3-1. Connection-Oriented Stream Sockets
WithVMCIsocketsandTCPsockets,theserverwaitsfortheclienttoestablishaconnection.Afterconnecting, 
theserverandclientcommunicatethroughtheattachedsocket.InVMCIsockets,avirtualsocketcanha
ve
onlytwoendpoints,andtheserver cannotinitiateaconnectiontotheclient.InTCPsockets,morethantwo
endpointsarepossible,thoughrare,andtheservercaninitiateconnections.Otherwise,theprotocolsare
identical.
