The present invention is related to a method for providing control in a communication network (1 ) comprising one or more network elements (3, 7). The method comprises configuring a switch (4) of a first network element (3) of the communication network (1 ) and a local controller (2) of the first network element (3) by means of one or more configuration messages received (6a) from a centralized controller (5) and controlling one or more packet flows between one or more of the switch (4) of the first network element (3), the local controller (2) of the first network element (3), the centralized controller (5) and one or more second network elements (7) based on the configuration of the switch (4) and of the local controller (5) of the first network element (3). The present invention is furthermore related to a first network element (3) comprising a switch (4) and a local controller (2). The switch (4) and the local controller (2) are adapted to receive (6a, 6b) configuration messages from a centralized controller (5) and adapted to control one or more packet flows between one or more of the switch (4) of the first network element (3), the local controller (2) of the first network element (3), the centralized controller (5) and one or more second network elements (7) based on the configuration of the switch (4) and of the local controller (2) of the first network element (3). |
