EF (101110): EF (Expedited Forwarding PHB). It specifies the highest priority of the internet service.
Class-Selector PHB: It specifies that the DSCP mark is “XXX000” where X can be “0” or “1”. The class of

service classes which require the corresponding bandwidths and caches. Each service class has three
packet-loss priorities.
