Abstract: The present disclosure discloses a method and device for calculating a network path. Wherein, the method includes that: a network control node calculates a forwarding path from a source node to a destination node according to capability information of a forwarding node and a constraint condition. By the method, correctness of calculating the SDN path and network applicability may be improved.

Abstract: The embodiment of the present document provides a collaboration method in a distributed resilient network interconnected system, including: a link aggregation control protocol (LACP) system receiving system parameters notified by a distributed relay control protocol (DRCP) system, and using the system parameters of the DRCP system as system negotiation parameters of the LACP system. The embodiments of the present document further provide a link aggregation control protocol (LACP) system, wherein the LACP system includes a receiving module and a controlling module, the receiving module is configured to receive system parameters notified by a distributed relay control protocol (DRCP) system; the controlling module is configured to take the system parameters of the DRCP system as system negotiation parameters of the LACP system. The embodiment of the present document achieves a collaboration between the LACP system and the DRCP system.

Abstract: A method and apparatus for dynamically switching a gateway of a DRNI are provided. The method includes: synchronizing information of main and backup gateways of each portal system between a portal system of a DRNI end point and other portal systems of the present end point; the portal system detecting whether an event which triggers switching the main and backup gateways occurs or not; and updating a gateway of a service or session when the event which triggers switching the main and backup gateways is detected, a portal system in which a new main gateway of the service or session is located starting to forward the service or session via the main gateway, and a portal system in which the backup gateway of the service or session is located stopping forwarding the service or session via the backup gateway.
