基于带缓冲的双通道开关技术的网络隔离器设计

在对网络隔离技术进行分析的基础上,研究利用网络隔离技术来解决网络安全问题。目前的网络隔离产品大多是采用基于硬件的开关控制,受限于现有硬件技术条件,并且厂家要根据不同用户要求而开发生产针对特定应用的网闸,不能方便地同时支持多种应用。提出了一种改进的安全隔离网闸实现方案。重点是模块化和软件方式实现开关技术,采用独立的软件开关控制和模块化设计,解决了现有物理隔离网闸产品在硬件开关控制和所支持应用上的限制,这种采用软件实现开关功能的方式避免基于现有硬件技术的可用性和寿命时间的限制。

Network Isolation of Based on Buffered Dual Channel Switching Technology

The current network isolation products are mostly hardware-based switch control,subject to the conditions existing hardware technology,and manufacturers according to different user requirements and the development and production of application-specific gateway,you can not easily support multiple applications simultaneously.An improved security isolation gate-way implementations in this paper.Focus is modular and realization of software switching technology,the use of independent software switch control and modular design,the solution of the existing physical isolation network gateway products in the hardware switch on the control and limitation of supported applications,this switch functions implemented in software the way to avoid the availability based on existing hardware technology and life time limits.
