As additional qualified users are identified, they can be added to the network. (Qualified Users are UA constituents who have research and/or education applications, which need high bandwidth and/or QoS, or need access to high bandwidth application through other institutions, which are available through this national network.) If the backbone needs to be upgraded, other OC12 rings can be added. Because UA already has a robust campus network in place, the projects requiring high bandwidth and QoS can be segregated on the new ATM network.  UA has committed resources to continue this connection beyond the grant period.
