Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0027] see figure 1 , which is a flowchart of a network security protection method provided by an embodiment of the present invention, the method includes:

[0028] Step 101: When a signal failure on a link of the optical transport network is detected, determine the faulty optical transport network interface according to the signal failure;

[0029] Step 102: forward the signal failure to the packet transport network interface corresponding to the optical transport network interface according to the service configuration path;

[0030] Step 103: sending a forward failure indication or an alarm indication signal to the packet transmission network through the packet transmission network interface, so as to trigge...

Abstract

The utility model relates to a network security protection method, an apparatus, and a system. The method comprises: determining the optical transmission network interface of a fault according to the signal failure when the signal failure upon the link of an optical transmission network is detected; transmitting the signal failure to a grouping transmission network interface corresponding to the optical transmission network interface according to the business configuration path; sending forward failure indication or alarming indication signals to the grouping transmission network via the grouping transmission network interface, thus to trigger the grouping transmission network to carry out automatic protection switching; when the fault signal of the grouping business channel of the grouping transmission network is detected, determining the grouping transmission network interface of the fault according to the fault signal of the grouping business channel; transmitting the fault signal to an optical network interface corresponding to the grouping transmission network interface according to the business configuration path; and sending signal failure to the optical transmission network via the optical transmission network interface to trigger the optical transmission network to carry out subnet connecting protection switching.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a network security protection method, device and system. Background technique [0002] In the packet optical transmission network (P-OTN, Packet-Optix Transmission Network) structure, the OTN and packet service hybrid transmission and bridging device (herein referred to as the hybrid transmission and bridging device), realize the packet transmission network (PTN, Packet Transmission Network) and Time Division Multiplexing (TDM, Time Division Multiplexing) dual-plane service interworking, so as to achieve the purpose of smooth evolution from the service carried by the TDM equipment to the service carried by the PTN. [0003] During the research and practice of the prior art, the inventors of the present invention found that in the existing implementations, although both optical transmission (OTN, Optix Transmission Network) and PTN have powerful protection functions...
