Embodiment 1

[0036] Example 1, see figure 1 , a mimetic network operating system construction device, including a variant management unit, a NOS unit and a mimetic unit;

[0037] The variant management unit is composed of two sub-units, the variant template pool and the variant management. The variant template pool is composed of multiple heterogeneous software-defined controllers, which use different languages, different algorithms, Different operating systems are designed and implemented, or the controller of the same source code is compiled and generated by using diversified compilation technologies; the variant management subunit manages the variant template pool, and monitors, schedules and cleans the variants;

[0038] NOS unit, selected by the variant management unit from the variant template pool according to a certain strategy m The NOS after the instantiation of the template is composed, among which, m ≥1, each selected NOS independently receives information from the mimetic un...

Abstract

The invention discloses a construction device of a mimicry network operating system. The construction device includes a variant management unit, an NOS unit and a mimicry unit. The variant management unit is composed of a variant template pool and a variant management sub unit. The NOS unit is composed of multi-template instantiated NOSs selected from the variation template pool. The mimicry unit receives calculation results from the NOS unit and executes a multi-mode decision. The invention also discloses a method based on the construction device of the mimicry network operating system. The method includes the steps of distributing a message from an underlying network to each heterogeneous network operating system that runs online, detecting the real-time state thereof by a monitoring agent built in each network operating system, and feeding back results to the variant management unit, each running network operating system independently executing the calculation; and subjecting the calculation result from each network operating system to multi-mode decision. The invention also discloses a mimicry network operating system, which comprises a variant template pool, a variant management layer, an NOS layer and a mimicry layer.

Description

technical field [0001] The present invention relates to the technical field of cyberspace security, and in particular, to a mimetic network operating system, a construction device and a method. Background technique [0002] Software Defined Networking (SDN) makes the network more flexible, open and programmable by decoupling the network control plane from the network forwarding plane. It is considered to be a revolutionary technology that is expected to change the future network architecture. The industry has attracted extensive attention and is gradually applied to the commercial network field. However, SDN technology is also a double-edged sword. While improving network performance and flexibility, the centralization of network control introduces many new security issues. Due to the global network view and control, once an attacker controls or paralyzes its backbone - A software-defined controller (or network operating system) can directly tamper or paralyze the entire ne...
