Slide 10. High Speed IP Environments
Frame Relay has evolved to address the mass market’s increasing bandwidth demand by supporting connectivity up to DS-3 speeds. However, niche markets exist where end user IP applications require much more bandwidth. IP over SONET is one such solution. IP over SONETs’ appeal for many users has been its management simplicity and transport efficiency when compared to alternate solutions such as IP over ATM.
To address the ever increasing bandwidth requirements of the campus backbone environment ATM has also been an option for end users. However, with the arrival of Gigabit Ethernet it looks as if ATM in the campus will be relegated to niche applications where multi-protocol and QoS support are of prime importance. Gigabit Ethernet is a more familiar architecture in many users’ minds providing them with a “hassle free” backbone upgrade option at a compelling price/performance ratio.
