A system for exchanging information in an on-chip communication network using optical flow information for communication between Intellectual Property cores. The information is exchanged between a plurality of initiators and targets in the Intellectual Property cores. The system includes a router for propagating optical flow information from the initiators to the targets. Each initiator includes an interface to convert the traffic generated by the initiator and transmit it in the form of an optical flow within the on-chip communication network, and each target includes an interface to convert information from the optical form into the electrical form. The system is organized as a parametric system and includes programming module to define a first set of high level parameters, a second set of initiator network interface parameters and a third set of target network interface parameters.
