Depending on your context, “TCP Splitter” usually refers to either a software utility used to duplicate data streams, or a hardware concept used in high-speed network monitoring. 1. Commercial Software Utility (Most Common)
Most people looking for a “TCP Splitter” are looking for the software utility developed by AGG Software.
What it does: It takes a single incoming TCP or UDP network data stream and splits (duplicates) it into two or three identical data streams.
Why it is used: Standard Windows networks usually limit a single port connection to one application. A TCP Splitter bypasses this limitation so multiple applications can process the exact same data simultaneously. Common Use Cases:
Navigation Systems: Splitting NMEA 0183 data coming from a GPS sensor so that two separate navigation programs can read the live location at the same time.
Industrial Automation: Sending data from telemetry sensors to a main control panel while simultaneously diverting a clone of that data to a background backup logger.
Security Bridging: Securely extracting data from an isolated production network to the internet without allowing external traffic back in.
Key Features: It can convert protocols on the fly (e.g., changing UDP to TCP), handles connection drops with automatic data buffering, and can run silently as a Windows background service. 2. Networking Architecture (Hardware & Protocols)
In academic computer science and advanced networking, “TCP-Splitter” refers to an engineered solution used for high-speed network flow monitoring.
