Abstract

The invention discloses unicast methods, a virtual switch, an SDN controller and a memory medium. A unicast method comprises the steps that the SDN controller receives a unicast request sent by a first virtual switch; a unicast target virtual machine is obtained according to the unicast request; a unicast forwarding rule is generated according to the unicast target virtual machine; and the unicastforwarding rule is sent to a second virtual switch, thereby enabling the second virtual switch to send a unicast message to the unicast target virtual machine.

Description

technical field [0001] The invention relates to the technical field of virtualized networks, in particular to a unicast method, a virtual switch, an SDN controller and a storage medium. Background technique [0002] In a traditional network environment, when non-technical personnel use unicast-related applications, it often causes unicast flooding of the entire network environment, and even paralyzes the entire network environment. The traditional solutions include: using the storm-control command on the host interface to control all outgoing unicasts from the source host, adjusting the aging time of the MAC and ARP tables, pruning the VLAN on the trunk port on the aggregation switch, and setting all Layer 2 interfaces on the aggregation switch Configure switchportblockunicast and other methods. [0003] However, the existing methods for preventing unknown unicast flooding have high complexity, low stability, and great dependence on the network hardware environment, and can...
