Abstract:
The present application discloses a flow forwarding method, device, and system. The method includes: receiving, by an edge node, an intelligent routing service request packet, and the packet includes a constraint condition required for establishing the intelligent routing service; if the edge node does not find, in a flow table, a corresponding matching flow table entry of characteristic information, sending, by the edge node, a first message to a controller, where the first message includes identification information of the edge node and the characteristic information and the edge node is an ingress edge-node or an egress edge-node that receives the packet; receiving, a first flow table entry sent by the controller, where the first flow table entry is generated according to the first message and meets the constraint condition; and processing, according to the first flow table entry, a packet sent by the user side device.
Abstract:
Disclosed is a method and a device for protecting service reliability, and the service reliability in the network virtualization system provided by the present disclosure may be ensured. In an embodiment of the present disclosure, a master node having a control function obtains the current service type information and notifies a slave node of the current service type information, for enabling the slave node to determine a main virtual link and a backup virtual link according to the service type information and to perform the failure detection, and when detecting that the main virtual link has failure and the backup virtual link has no failure, a service data message is switched to be transmitted on the backup virtual link, to ensure non-interrupted transmission of a service data message in a brand-new system architecture provided by the present disclosure, so as to ensure the service reliability.
