Abstract
A routing system transfers data packets of real time communication services of a call, and includes a converter receiving media gateway control protocol encoded first control data and processing the first control data to obtain second control data. The system, based on the first control data, allocates a first transport address for a first routing port for incoming data packets, and allocates a second transport address for a second routing port for outgoing data packets. A central control entity controls a central control entity controlled network of forwarding elements, and determines a static pathway through the network of forwarding elements based on the second control data. A first end of the static pathway corresponds to the first routing port and a second end corresponds to the second routing port. The central control entity controls a data plane flow of a stream of the data packets along the static pathway.
