Passive route control of data networks
A system and a method for controlling routing of data over multiple networks. Accordingly, a system and method are provided for routing data between a first point and a second point. The method comprises passively monitoring at least one data flow characteristic associated with a data flow on a first path, comparing the at least one data flow characteristic, associated with the data flow on the first path, to an associated data flow requirement of a policy, switching the data flow to a second path if the at least one data flow requirement is not met, passively monitoring at least one data flow characteristic associated with the data flow on the second path, and comparing the at least one data flow characteristic associated with the data flow on the second path with the associated data flow requirement of the policy.
