Topwalk-FGAP

Topwalk Fiber Gap (Topwalk-FGAP) is unidirectional communication solution (Simplex) that completely eliminates the risk of data leakage or reverse transmission.

It leverage the unidirectional optical transmission capability of dedicated optical splitters and a proprietary physical architecture. Featuring a "2+1" multi-host architecture, it employs an independently developed optical one-way isolator to achieve purely physical unidirectional data transmission.

Core Values

One-Click Health Check

It supports one-click health checks to effectively monitor system status and detect potential abnormalities in real time.

Safeguarding

It provides security protection for the file exchange module, database import module, and client endpoints. It incorporates multi-dimensional data inspection capabilities—including virus scanning, content filtering, and content validation—to further enhance the security of data exchange processes.

Data Fault Tolerance

When fault tolerance is enabled, the destination endpoint performs hash-based summary comparison. This enables one-click export of summaries and headers for lost data, as well as one-click retransmission of imported source data, ensuring complete data integrity.

File Exchange

It supports file collection and one-way transfer via FTP, SMB, NFS, and other file servers. For files with duplicate names on the destination server, it provides policies for renaming, overwriting, or discarding the files.

Database Exchange

It supports data collection and one-way transmission for databases including ORACLE®, MYSQL®, SQLSERVER®, and Dameng DM®. It enables data exchange between heterogeneous databases and offers policies for handling primary key conflicts in the destination database server—including overwrite, insert into backup tables, and discard. For trigger-based collection types, it supports update operations without relying on primary key discard or insert policies.

Product Advantages

Robust Security Protection System

The system adopts TopOS, an independently developed operating system with proprietary intellectual property rights. Compared to other open-source Linux systems, TopOS is more streamlined, efficient, robust, and secure. It not only removes and disables all unnecessary and security-compromising operation commands and modules but also performs security hardening on certain modules. The streamlined TopOS retains only the system core modules and the essential modules required for software operation.

Efficient Health Detection Method

The unidirectional isolation gateway supports a wide range of health detection algorithms, enabling comprehensive checks of devices, systems, and service operational status at both the network and application layers. It generates alerts, facilitates rapid fault localization, and ensures uninterrupted service.

Rapid Recovery Mechanism

The system provides flexible backup and restore functions. It not only allows for manual backup of system and business configurations, but also enables timely restoration of system configurations in the event of a sudden attack on the system server, ensuring normal system operation.

Broad Business Scenarios

The system supports multiple transmission methods, including file-based, database-based, and file client-based transmission, catering to the unidirectional transmission requirements of various application industry scenarios.

Powerful Security Application Hardware

The dedicated optical splitter is a passive device connecting the sending unit and the receiving unit. It has no control channel and, compared to electrical unidirectional isolation based on programmable logic chips, offers inherent security advantages.

Application Scenarios

Topwalk FGAP enables one-way transmission of files, database data, and other application data from low-security-level networks to high-security-level networks, making it ideally suited for government agencies, defense organizations, and large-scale enterprises.
