UDPspeeder - A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction,for All Traffics(TCP/UDP/ICMP)

•    C++

---

A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction. Assume your local network to your server is lossy. Just establish a VPN connection to your server with UDPspeeder + any UDP-based VPN, access your server via this VPN connection, then your connection quality will be significantly improved. With well-tuned parameters , you can easily reduce IP or UDP/ICMP packet-loss-rate to less than 0.01% . Besides reducing packet-loss-rate, UDPspeeder can also significantly improve your TCP latency and TCP single-thread download speed.

Ethr - Ethr is a Network Performance Measurement Tool for TCP, UDP & HTTP.

•    Go

---

Ethr is a cross platform network performance measurement tool written in golang. Goal of this project is to provide native tool for network performance measurements for 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 insipiration from existing open source network performance tools and builds upon those ideas. It is very similar to iPerf3 for bandwidth measurements for TCP. iPerf3 has many more options for doing bandwidth measurements such as throttled testing, richer feature set, while Ethr has support for multiple threads, ability to scale to 1024 or even higher connections, multiple clients to single server etc. It is similar to latte on Windows or sockperf on Linux for doing latency measurements.

turbo - Turbo is a framework built for LuaJIT 2 to simplify the task of building fast and scalable network applications

•    Lua

---

Turbo is a framework built for LuaJIT 2 to simplify the task of building fast and scalable network applications. It uses a event-driven, non-blocking, no thread design to deliver excellent performance and minimal footprint to high-load applications while also providing excellent support for embedded uses. The toolkit can be used for HTTP REST API's, traditional dynamic web pages through templating, open connections like WebSockets, or just as high level building blocks for native speed network applications. First and foremost the framework is aimed at the HTTP(S) protocol. This means web developers and HTTP API developers are the first class citizens. But the framework contains generic nuts and bolts such as; a I/O loop, IO Stream classes, customizeable TCP (with SSL) server classes giving it value for everyone doing any kind of high performance network application. It will also speak directly to your exising C libraries, and happily also create native C struct's for the ultimate memory and CPU performance.

socket - Async, streaming plaintext TCP/IP and secure TLS socket server and client connections for ReactPHP

•    PHP

---

Async, streaming plaintext TCP/IP and secure TLS socket server and client connections for ReactPHP. The socket library provides re-usable interfaces for a socket-layer server and client based on the EventLoop and Stream components. Its server component allows you to build networking servers that accept incoming connections from networking clients (such as an HTTP server). Its client component allows you to build networking clients that establish outgoing connections to networking servers (such as an HTTP or database client). This library provides async, streaming means for all of this, so you can handle multiple concurrent connections without blocking.

f-stack - F-Stack is an user space network development kit with high performance based on DPDK, FreeBSD TCP/IP stack and coroutine API

•    C

---

With the rapid development of Network Interface Cards the poor performance of data packet processing with the Linux kernel has become the bottleneck in modern network systems. Yet, the increasing demands of the Internet's growth demand a higher performant network processing solution. Kernel bypass has emerged to catch more and more attention. There are various similar technologies such as: DPDK, NETMAP and PF_RING. The main idea of kernel bypass is that Linux is only used to deal with control flow; all data streams are processed in user space. Therefore, kernel bypass can avoid performance bottlenecks caused by kernel packet copying, thread scheduling, system calls, and interrupts. Furthermore, kernel bypass can achieve higher performance with multi-optimizing methods. Within various techniques, DPDK has been widely used because of it's more thorough isolation from kernel scheduling and active community support. To deal with the increasingly severe DDoS attacks the authorized DNS server of Tencent Cloud DNSPod switched from Gigabit Ethernet to 10-Gigabit at the end of 2012. We faced several options: one is to continue to use the original network stack in the Linux kernel, another is to use kernel bypass techniques. After several rounds of investigation; we finally chose to develop our next generation of DNS server based on DPDK. The reason is DPDK provides ultra-high performance and can be seamlessly extended to 40G, or even 100G NIC, in the future.

zaver - Yet another fast and efficient HTTP server

•    C

---

Yet another fast and efficient HTTP server. The purpose of Zaver is to help developers understand how to write a high performance server based on epoll. Although Nginx is a good learning example, its complexity and huge code base make people discouraged. Zaver uses as few codes as possible to demonstrate the core structure of high performance server like Nginx. Developers can lay a solid foundation by learning Zaver for further study in network programming.

A CS development framework based on small-to-medium sized refining, covering computer-side, web-side, and mobile-side full-platform system templates, will include some commonly used repetitive function codes, such as network communication mechanisms, in most one-to-many system designs. Client version control, account control management, password modification, announcement management, server configuration, various common windows, etc., and most small and medium-sized systems just need simple rights management.  This framework contains four client-side modes, the first commonly used winform client, the second is the wpf client, the third is the asp.net mvc mode, and the fourth is the client of the Android platform. You can choose a mode on winform and wpf clients, then your system provides some functions (such as report viewing) to asp.net, and then provide an Android app for mobile phone use, if the server is assumed in the cloud, all People can interact with anytime, anywhere, data flow, all account models are unified, the browser is also convenient for some people who only need to view the report users do not need to deploy the client. Of course, the client can provide more powerful features.
