Problems solved by technology

[0007] However, once the vBGP component fails, the multi-path load balancing route changes during the period, and the route on the virtual switch vSwtich cannot be converged, and the business traffic will still be sent to the abnormal path or virtual machine, resulting in business interruption

Abstract

The invention provides a multi-path business convergence method and device in an SDN (Software Defined Network) and a storage medium, which are used for solving the technical problem of multi-path business convergence in the SDN. In the invention, the SDN controller monitors the alarm message of a vBGP component, and when the related fault of the vBGP component is found to cause the synchronization abnormity of the BGP routing information, the SDN controller actively issues the escape traffic table to the virtual switch, so that all forwarding flow tables generated by the vBGP routing on the virtual switch are invalid. Through the escape traffic table, all the east-west business traffic by the exit gateway to be forwarded, so that the situation that after the vBGP component fails, a virtual machine in a target VNF fails, and an equivalent multipath forwarding traffic table on a virtual switch cannot be updated and converged in time, so that part of the east-west business traffic are cut off is avoided. Therefore, the east-west multi-path business can be converged to a normal virtual machine by the exit gateway.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a multipath service convergence method, device and storage medium in an SDN network. Background technique [0002] In network overlay networking, tunnel encapsulation is performed by physical switches. The advantage of this networking solution is that the forwarding performance of physical network devices is relatively high, and it can support the networking and intercommunication between non-virtualized physical servers. [0003] In the host overlay network, the virtual device is used as the edge device of the overlay network. This networking solution is suitable for server virtualization scenarios and supports mainstream Hypervisor platforms such as KVM and CAS. [0004] Hybrid Overlay refers to the scenario where both OVS (Openflow Virtual Switch) and hardware switch (Leaf) exist in the entire network. In the hybrid overlay network, network overlay and ...
