Embodiment Construction
[0020] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0021] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.
[0022] Such as figure 1 As shown, the security interaction method of the present invention comprises the following steps:
[0023] Step 101: receiving a packet entry message, wherein the packet entry message is sent by the first optical switching node in response to receiving a connection request from a service terminal;
[0024] Step 102: triggering attack detection in response to receiving a packet incoming message;

The invention discloses a software-defined optical network safe interaction method and a system thereof. The safe interaction method comprises the following steps: receiving packet incoming message; triggering attack detection in response to receiving a packet incoming message; if a security attack is detected, recording the security attack, canceling the service connection request, and counting the security threat degree, if the threat level is higher than the threshold, triggering the PKI module to update the private key, if no security attack is detected, using the controller's private keyfor decryption, calculating the optical route, encapsulating the routing related information in the flow table entry of the change status message, encrypting the information in the change status message using the private key of the first optical switching node, receiving an alarm message or a reply message, if no security attack is detected, transmitting service data through the established optical path, and if a security attack is detected, recording the security attack, canceling the service connection request, and counting the security threat degree.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and system for safe interaction of a software-defined optical network. Background technique [0002] Software-defined networking (SDN), as an open network architecture and technical system based on software-defined ideas, its core is that the control and forwarding functions of network nodes are separated from each other, and data layer devices only retain simple forwarding functions. Through the centralized control of the network by the controller, the openness and transparency of the underlying physical network to the upper network application can be realized. Thanks to its flexible, efficient, and programmable technical advantages, SDN can realize energy-based control of the network. The Software Defined Optical Network (SDON) architecture based on the idea of SDN is mainly divided into data forwarding plane, control plane and application plane. Wherein, the control plan...
