Method and system for cooperation of distributed elastic network interconnection systems

The invention provides a method for cooperation of distributed elastic network interconnection systems. The method comprises the step that after an LACP system receives systemic parameters announced by a distributed relay control protocol (DRCP) system, the systemic parameters of the DRCP system are used as system negotiation parameters of the LACP system. The invention further provides an LACP system which comprises a receiving module and a control module. The receiving module receives the systemic parameters announced by the DRCP system, and the control module regards the systemic parameters of the DRCP system as the system negotiation parameters of the LACP system. By means of the method, cooperation of the LACP system and the DRCP system is achieved.
