Difference between Total_Lenght and Shape_Lenght fields

Good day to everyone,

I've found some discrepancies in the attribute table of the routes when I solve the Closest Fascilitie. Network analyst writes the result into a field "Total_Lenght" (in some units, as I understand - those units that I've choosed while creating Network Dataset). When I export the Routes layer to the geodatabase, automaticly there is created field "Shape_Lenght". BUT! The value is different then in "Total_Lenght". The problem is not in the map units - they are the same that in the network dataset.

Anybody can explain what's happening with that both values? :)
