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 security interaction method and system for a software-defined optical network. The security interaction method includes the following steps: receiving a packet incoming message; triggering attack detection in response to receiving the packet ingress message; if a security attack is detected, recording a log If no security attack is detected, the service connection request is cancelled, and the security threat level is counted; if the threat level is higher than the threshold, the PKI module is triggered to update the private key; if no security attack is detected, the private key of the controller is used to decrypt; route; encapsulate the relevant information of the route in the flow table entry of the change state message; use the private key of the first optical switching node to encrypt the information in the change state message; receive alarm information or reply message; if no security attack is detected , the service data is transmitted through the established optical path; and if a security attack is detected, the security attack is recorded, the service connection request is canceled, and the security threat level is counted.
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...
