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

Disclosed are a network security protection method, device and system. Said method includes: when a signal fault on a link of an optical transmission network is detected, determining, according to the signal fault, an optical transmission network interface where a failure has occurred (101); according to a service configuration path, transferring said signal fault to a packet transmission network interface corresponding to said optical transmission network interface (102); through said packet transmission network interface, transmitting a forward fault indication or an alarm indication signal to the packet transmission network in order to trigger said packet transmission network to perform an automatic protection switching (103); and / or, when a failure signal on a packet service channel of the packet transmission network is detected, determining, according to the failure signal on said packet service channel, a packet transmission network interface where a failure has occurred (104); according to the service configuration path, transferring said failure signal to an optical transmission network interface corresponding to said packet transmission network interface (105); through said optical transmission network interface, transmitting the signal fault to the optical transmission network in order to trigger said optical transmission network to perform a sub-network connection protection switching (106).

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...
