<p>In a (communication) network comprising a plurality of network domains (100, 200, 300) in which switches (S1.1, S1.2, S1.3, S1.4, S1.5, S1.6; S2.1, S2.2, S2.3, S2.4, S2.5, S2.6; S3.1, S3.2, S3.3, S3.4, S3.5, S3.6) and controllers (10, 20, 30) are separated, said controllers (10, 20, 30) providing the information to which neighbour switches are to forward data packets, the conception of inter-domain communication is introduced: A local controller (10) alerts another local controller (30) enabling this other local controller (30) to perform process steps in preparation of arrival of a data packet prior to that data packet arriving at its network domain (300).</p> |
