Abstract: Disclosed are a method and system for information interaction between systems in a same portal in a distributed resilient network interconnection, wherein the method is applied to each system in an portal in a link aggregation group, including: sending a distributed relay control protocol (DRCP) message through an intra-portal interface, wherein at least system information of a present system is carried; after receiving a DRCP message sent by an adjacent system, if it is determined that the present system and the adjacent system can form one portal in the distributed resilient network interconnection, determining an operational Key value of the present system. The system includes: a sending state machine, a receiving state machine, a negotiating state machine, a synchronizing state machine and a periodic sending state machine.

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.

Abstract: A method and device for distributed link aggregation group service handover are disclosed in the present document. The method includes: when an unavailable port appears in a distributed link aggregation intra-end system, the intra-end system determining a service currently corresponding to the unavailable port as a service to be handed over; or, when an unavailable intra-end system appears in a distributed link aggregation portal, an adjacent intra-end system of the intra-end system determining a service currently corresponding to the unavailable intra-end system as a service to be handed over; and the intra-end system that determines the service to be handed over determining a backup port of the service according to a port sequence configured for the service in advance, canceling a corresponding relationship between the service and the unavailable port, and establishing a corresponding relationship between the service and the backup port.
