The Netcap (NETwork CAPture) framework efficiently converts a stream of network packets into platform-neutral type-safe structured audit records that represent specific protocols or custom abstractions. These audit records can be stored on disk or exchanged over the network, and are well-suited as a data source for machine learning algorithms. Since parsing of untrusted input can be dangerous and network data is potentially malicious, a programming language that provides a garbage-collected memory-safe runtime is used for the implementation.

Built in Go, gnet is ultra-fast and memory efficient based on the event-driven mechanism. It's designed to create a networking server framework for Go that performs on par with Redis and Haproxy for networking packets handling. gnet is lock-free during the entire runtime, which keeps gnet free from synchronization issues and speeds it up. gnet provides concise and easy-to-use APIs for users, it only exposes the essential APIs and takes over most of the tough work for users, minimizing the complexity of business code so that developers are able to concentrate on business logic instead of the underlying implementations. gnet supports multiple protocols/IPC mechanism: TCP, UDP and Unix Domain Socket, enabling you to develop a variety of networking applications. gnet is devised as a cross-platform framework, as a result, it works faultlessly on multiple platforms: Linux, FreeBSD, DragonFly BSD, Windows.

...Read pcap files or sniff live interfaces (where tshark is permitted). Filter pcaps or live captures using Wireshark's display filters. Reassemble and inspect TCP and UDP flows. View network conversations by protocol. Copy ranges of packets to the clipboard from the terminal. Written in Golang, compiles to a single executable on each platform - downloads available for Linux, macOS, BSD variants, Android (termux) and Windows. Termshark is pre-packaged for the following platforms: Arch Linux, Debian (unstable), FreeBSD, Homebrew, MacPorts, Kali Linux, NixOS, SnapCraft, Termux (Android) and Ubuntu.

Ethr is a cross-platform network performance measurement tool written in golang. The goal of this project is to provide a native tool for comprehensive network performance measurements of bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems. Ethr takes inspiration from existing open-source network performance tools and builds upon those ideas. For Bandwidth measurement, it is similar to iPerf3, for TCP & UDP traffic. iPerf3 has many more options for doing such as throttled testing, richer feature set, while Ethr has support for multiple threads, which allows it to scale to 1024 or even higher number of connections, multiple clients communication to a single server etc. ...

NFF-Go is a set of libraries for creating and deploying cloud-native Network Functions (NFs). It simplifies the creation of network functions without sacrificing performance. We are now supporting AF_XDP and supporting(almost) getting packets directly from Linux. So you do not need to write 3(three) different applications to process packets coming from different type of drivers of PMDs. You just write everything in NFF-Go, and it can dynamically use whatever you would like underneath. Contact us if you need help.

Testing distributed systems under hard failures like network partitions and instance termination is critical, but it's also important we test them under less catastrophic conditions because this is what they most often experience. Comcast is a tool designed to simulate common network problems like latency, bandwidth restrictions, and dropped/reordered/corrupted packets. It works by wrapping up some system tools in a portable(ish) way. On BSD-derived systems such as OSX, we use tools like ipfw and pfctl to inject failure. On Linux, we use iptables and tc. Comcast is merely a thin wrapper around these controls. Windows support may be possible with wipfw or even the native network stack, but this has not yet been implemented in Comcast and may be at a later date. ...
