Embodiment Construction

[0038] The present invention will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but do not limit the present invention.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides an SDN-based remote stream mirroring control method, based on a controller, including:

[0040] S11: Determine a mirroring path between the mirroring source switch and the mirroring destination switch according to remote flow mirroring configuration information and network topology information;

[0041] S12. Send a mirroring flow table to each switch in the mirroring path, so that each switch mirrors and outputs the monitored target service flow from the mirroring source switch to the mirroring destination switch according to the mirroring flow table ; Wherein, the mirror flow table carries matching field information designated for the target service f...

Abstract

The invention discloses an SDN (Self-Defending Network)-based remote flow mirroring control method, an implementation method and related equipment, and relates to the field of communication. The control method is used for implementing a remote flow mirroring function for monitoring network traffic in an SDN. The control method comprises the steps of: determining a mirroring path between a mirroring source switch and a mirroring destination switch according to remote flow mirroring configuration information and network topology information; and sending a mirroring flow table to each switch in the mirroring path, so that each switch outputs a monitored target service flow in a mirroring manner from the mirroring source switch to the mirroring destination switch according to the mirroring flow table, wherein the mirroring flow table carries matching field information specified for the target service flow and forwarding action information corresponding to each switch.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to an SDN-based remote stream mirroring control method, implementation method and related equipment. Background technique [0002] Network traffic monitoring is a common application in network communication, which can be realized through mirroring technology. [0003] In the current mirroring technology for monitoring network traffic, users or network administrators are required to configure remote destination mirroring on remote switches. Each mirroring configuration requires a session to manage, which takes up more resources. Moreover, when the switch performs port data mirroring or forwarding the mirrored stream, an additional physical port needs to be occupied as a reflection port for data conversion. If you want to mirror the incoming and outgoing traffic of the source port, you must turn off the MAC learning function on the mirrored VLAN interface of the source switch...
