Architecture Design Considerations
MAY 2004
The
following design considerations are a reference criterion for the actual design
of the network architecture and can also be used in vendor equipment feature
selection. Designs will be selected based on the amount of design
considerations met per design and vendor. The most design considerations met at
the best cost with the most features will be considered.
