Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] see figure 1 , is the infrastructure of VMware ESX server. It can be seen that ESX can be divided into two parts: one is the Service Console (service controller) used to provide management services; the other is the core of ESX, which mainly provides virtualization Ability of VMKernel (Virtual Kernel).

[0019] see figure 2 , the redundant architecture of the safety encryption equipment of CBTC system of the present invention, comprises two hardware platforms, and each described hardware platform installs VMware ESX server, and each described VMware ESX server installs the virtual operating system of OpenBSD.

[0020] The hardware platform includes CPU, memory, at least one network adapter and disk drive, and SCSI adapter, fiber channel adapter or RAID controller.

[0021] Since the HA function is implemented by OpenBSD, not by VMware ESX server, through DirectPa...

Abstract

The invention discloses a redundancy framework of a security encryption device of a CBTC (Communication-based Train Control) system. The framework comprises two hardware platforms; each hardware platform is installed with a VMware ESX server; and each VMware ESX server is installed with a virtual operation system of OpenBSD. The framework is used for solving the problem on hardware updating and upgrading of security encryption devices in the rail traffic industry.

Description

technical field [0001] The invention relates to a security encryption device of a CBTC (communication-based automatic train control system) system in rail transit. Background technique [0002] The DCS (Data Communication Subsystem) network of the CBTC system has a large number of security encryption devices based on the OpenBSD (UNIX-like operating system) operating system. These security encryption devices guarantee the integrity and confidentiality of the CBTC data. Therefore, these security encryption devices The requirements for the stability and continuity of the equipment itself are very high. These security encryption devices are based on the OpenBSD operating system, and it is difficult to guarantee a sustainable hardware platform support within 10 years in terms of hardware selection. [0003] In order to meet the 10-year or 20-year continuity of the project's security encryption equipment, the DCS team needs to constantly search for a hardware platform that can c...
