To configure an email application, the application named e-
Mail was selected from the list of builtin models. OPNET provides preset configurations for email applications as well. The preset email configurations include Low Load, Medium Load, and High Load. The model also allows custom configuration via parameters such as Send(Receive) Inter- arrival Time which specifies the amount of time in seconds between consecutive sent (receive) operations, Send(Receive) Group Size which determines the number of emails messages per single sent(receive) operation, and E-Mail Size which defines the size of the email message in bytes. The email configurations for selected loads are shown in Table 3.4 show how to configure an email application. Fig. 4: Application Definition Specification

Before running a simulation, links verification was carried out to ensure that

Point-to-point and others link connections are valid.
• Enough transmitters and receivers to support all of the incoming and outgoing links.
• Data rates of the connected transmitter and receiver match the data rate of the link
• Transceivers support the attached link technology By pressing ctrl + l on the keyboard you can easily access a link verification window as shown in fig. 5 below Fig. 5: Links Verification window For this network scenario, the links verification was successful and there are no errors in all the links.
