Computer Networks continue to grow and diversify at unprecedented rate. Much of that diversification is in how the media are utilized. One can not truly understand networking, analyze alternatives or design good networks without a solid founding in how the media are utilized. This course will explore current and expected media technologies with the intent of understanding what they offer and the trade-offs they present. The course will cover both wireline (Ethernet, DOCSIS, MPLS, ATM) and wireless (802.11, Wi-Max, Zigbee, Bluetooth, etc). The course will analyze the technologies to consider their error characteristics, support for quality of service, congestion control, and security, and their manageability.
