I have some difficulties on network analysis,I want to run shortest path algorithm,
I don't know how to use ArcGIS to reveal the shortest route between the appointed points on the map, and if it's possible, can I also use this software to record and calculate the number of the real road be taken as shortest route?
I have about 200 point to be the origins and destinations on the map, and I need the shortest route between these appointed points (200*200) and let them revealed on the map
And then,record and calculate the number of the real road be taken as shortest route.
but i can only have one shortest route between two points once a time if i use the toolbar, i am wondering how can i make all the shortest routes between 200 points one time? do i have to use any progamming method?

There are two choose for you on NAServer. The NAServer is a MapServer object extension that can be used to perform network analysis in a stateless environment using ArcGIS Server.
For publishing a network analysis service you can check out this tutorial...
1.Closest Facility Analysis: displays the best routes between incidents and facilities.
2.OD Cost Matrix: (origin–destination (OD) cost matrix) a table that contains the network impedance from each origin to each destination.
and showing them in a map as openlayers, you can use ArcGIS Server Service.
example NAServer is here. beside this you have to define stops as following structure:
