Service requirements flow from user to application to device to network, becoming more specific along the way. If you were given an application requirement for end$-$to$-$end delay $($e$.$g$.,100ms)$ between an application server on one network and users on another network, for example, how might that translate into a delay in the network and devices? What types of service metrics could you use to measure it$?$
