Abstract [en]

This Master’s Thesis discusses the use of ATM versus Fast and Gigabit Ethernet in Campus Networks. Advantages and disadvantages with the technologies are presented from several different aspects, such as implementation issues, performance, manageability and affordability. Further more, the thesis identifies limitations with each technology. Finally, the thesis looks into the future evolution of ATM and Gigabit Ethernet and tries to answer the question of which of the two technologies will be a “winner” in the future.

In reality, ATM and Gigabit Ethernet are not equal substitutes for each other and should not be considered as such. Each technology is appropriate for specific applications. Gigabit Ethernet is appropriate in areas where high data throughput is required, but QoS is not a main concern. ATM is appropriate in environments where video, voice, and other delay sensitive traffic exist. Fast Ethernet has the best price/performance for regular desktop connections. If the desktops have low need for bandwidth, they can be connected with 10/100 MB NICs to 10-MB-ports in the switch. When the need arise, the connections can be upgraded to 100 MB. Gigabit Ethernet is also recommended for server connections. Depending on the need for bandwidth, Fast or Gigabit Ethernet is recommended.

For campus backbones, Gigabit Ethernet is recommended for all companies and organisations that do not run delay sensitive applications and therefor need QoS.
