Goreplay
GoReplay is a network traffic recording and replay tool used to capture live HTTP and binary protocol requests. It functions as a traffic shadowing proxy that duplicates incoming network requests to test environments and a utility for recording traffic to local or cloud storage for later analysis and playback.
The system is capable of processing non-textual data formats, such as Thrift and Protocol Buffers, allowing for the capture and replay of specialized application-to-application communication.
The tool supports live traffic capture and asynchronous duplication to validate infrastructure changes, perform regression testing with real data, and simulate load testing. It includes a playback engine that simulates original arrival intervals to mimic real-world traffic patterns.
Features
- Network Traffic Replay Tools - Provides utilities for capturing and replaying sequences of network requests to validate system behavior using real-world data.
- HTTP Traffic Shadowing - Duplicates live HTTP requests to a test environment to validate system behavior without affecting real users.
- Traffic Capture Frameworks - Records live HTTP and binary protocol requests to local or cloud storage for later analysis.
- Traffic-Replay Sandboxes - Validates application behavior and infrastructure changes by replaying captured production traffic in isolated environments.
- Binary Communication Protocols - Provides support for high-performance binary serialization and transport protocols like Thrift and Protocol Buffers.
- Network Traffic Analyzers - Analyzes network activity on specific ports to record requests without interfering with application performance.
- Network Traffic Processors - Processes and handles non-textual data formats like Thrift and Protocol Buffers during traffic capture and replay.
- Packet Capture Utilities - Records raw network traffic at the interface level for offline analysis and replay.
- Traffic Proxying - Intercepts and duplicates live network requests to a test environment as a shadowing proxy.
- Traffic Shadowing - Implements asynchronous traffic duplication to send live requests to a test server without affecting production.
- Traffic Playback Engines - Simulates original arrival intervals of recorded network requests to mimic real-world traffic patterns during replay.
- Regression Test Replayers - Replays captured production traffic against application code to verify that new changes do not introduce regressions.
- Traffic Serialization - Writes captured network traffic to local or cloud storage using serialized formats to preserve request timing.
- Protocol-Agnostic Processing - Processes non-textual data formats by treating payloads as raw bytes until a specific decoder is applied.
- Network Traffic Logs - Persists intercepted network request and response data to local files to preserve original timing.
- Multi-Destination Forwarding - Enables replicating captured network requests and sending them to multiple independent target servers.
- Load Testing Tools - Simulates realistic traffic patterns and volumes by replaying recorded requests at scale for performance evaluation.
- Testing and Service Virtualization - Tool for capturing and replaying live HTTP traffic for testing.
