AMINET Network 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.
