ALN has the ability to call upon ArcGIS Network Analyst to provide the routing capability.
I would need to know what is the amount of data involved in a typical request and response for a route calculation.
Are we talking kilobytes, several 10s of kilobytes or are megabytes involved. We need this to better understand
the limits when low-bandwidth, heavily contended networks are involved and what to and not to expect on such systems.
