About:
IpRelay is a TCP traffic shaping relay application designed to manage and control network data flow between clients and servers. It provides bandwidth limiting and latency simulation capabilities, making it an essential tool for testing application performance under constrained network conditions. This utility helps developers and network engineers validate how their systems behave with limited bandwidth or introduced delays.

Key Features:

Bandwidth throttling and rate limiting
Configurable latency injection
TCP connection forwarding and relay
Rule-based traffic filtering

Use Cases:

Testing application performance under poor network conditions
Simulating WAN latency for distributed systems development
Debugging network-related issues in controlled environments

Alternatives:

tc (traffic control) – Linux kernel utility with more complex configuration but no application-level relay features
netem – Network emulator built into Linux, requires root access and lacks standalone relay functionality
