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.

Method and device for calculating a network path

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.

Collaboration method and system in distributed resilient network interconnect system

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.
