In this paper the problem of the traffic and the available network capacity of the WDM mesh networks are defined, analyzed and calculated by applying the difference equations. The requests for connection in a time interval are generated by difference equations. By these equations (linear, square or exponential) the available capacity is calculated. To be this problem more complete it is studied as dedicated optical path protection one. The requests for connection of a node pair in a time interval forms the connection group size of this node pair. The difference equation methods are arithmetical and solve successfully the problems.
