As a Network engineer I have come across email and VoIP data. In my career I will get a chance to troubleshoot as well as configure protocols pertaining to Email and VoIP data. Both email and VoIP are important to a company. Without the two, a company will have a hard time communicating as well as have a hard time competing in today’s business world. This lab gives me a chance to talk about bandwidth, QOS (Quality of Service) and how it pertains to email and VoIP data. I will have the chance to explain and describe how background traffic affects both e-mail data and VoIP data.
Bandwidth, according is the amount of data that can be transmitted in a fixed amount of time. For digital devices, the bandwidth is usually expressed in bits per second or bytes per second. For analog devices, the bandwidth is expressed in cycles per second, or Hertz. The main reason traffic is affected is because it takes up a lot of bandwidth for all the data packets to be received completely without errors. One example is a 1.5 Meg T1 line. This is sufficient for voice calls using the proper codec; but add a video download on that line, along with...
