Open Source C Application Servers

Accelerate Your Network Performance with UCX. Collaboration between industry, laboratories, and academia to create an open-source, production-grade communication framework for data-centric and high-performance applications. Unified Communication X (UCX) is an award winning, optimized production proven communication framework for modern, high-bandwidth and low-latency networks. UCX exposes a set of abstract communication primitives which utilize the best of available hardware resources and offloads. These include RDMA (InfiniBand and RoCE), TCP, GPUs, shared Memory, and network atomic operations. UCX facilitates rapid development by providing a high-level API, masking the low-level details, while maintaining high-performance and scalability. UCX implements best practices for transfer of messages of all sizes, based on accumulated experience gained from applications running on the world’s largest datacenters and supercomputers.

LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.

rldns is an open-source, lightweight DNS server designed for Linux, NetBSD, FreeBSD, and OpenBSD. It supports both x86 and x86_64 architectures.

Naam Tamilar RTMP Server This project updated as open source for future use of Naam Tamilar Political Party. To contribute to the party and in some case if there is any possibilities if i cannot support them for long term. I thought of sharing this source code so in future it may be helpful for the community and party in which other software developers can help them to upgrade. This source is forked from - https://github.com/arut/nginx-rtmp-module and modified with multiple broadcast option. Stream Sources will be able to restreamed to RTMP Player, Youtube API, Facebook API, Twitch and any other plaftforms that supports streaming with API and stream key. All these can be published simultaneously at the same time. ForFirst UAT - User Acceptance Test has been conducted @ Pollachi Veerathamilatchi Sengodi Nenaivendal @ Sandaipettai Thidal, Pollachi on 19 August 2017 #3146 Viewed Simultaneously Streamed with 16 GB Ram, 500 GB SSD, Ubuntu 16.04 LTS Server with NTK RTMP Server

NetProg is an API in C language allowing an homogeneous programming of communicating applications on many operating systems. It covers all the need for applications that requires complex way of exchanging data in synchronous or asynchronous mode. Based on messages for exchanging data between clients and servers, it, moreover, access databases or files with the same message modelling.
