Abstract
A method for controlling a network. The network includes a plurality of forwarding elements (FE) connected with each other, one or more end hosts (EH) connected to one or more of the FE, and a controller for controlling the FE. The method includes installing packet processing rules for end-host control protocols (ECP) on the FE. When an ECP Request (ECPRQ) is received by an FE and the ECPRQ was not processed by the controller, the ECPRQ is provided to the controller and an ECP response is computed by the receiving FE based on extracted information from the ECPRQ mapped onto forwarding information based on mapping information if provided, otherwise if the ECPRQ was processed by the controller, the ECPRQ is forwarded according to forwarding information of the ECPRQ. When an ECP response (ECPR) is received by an FE, the ECPR is forwarded according to forwarding information.
