Military air to ground interdiction jets stationed in northern Africa may be required to support African Union missions from Sudan to Malawi. Having current topographic information is mandatory for mission success. The aircraft is connected to a fiber link to update the database just before take-off. The squadron commander has a mandate that the database update must be complete in less than one minute. If the topo database is 10 GB, and the link is SONET, what is the minimum standard rate required?
