Tsung is a distributed load testing tool. It is protocol-independent and can currently be used to stress HTTP, WebDAV, PostgreSQL, MySQL, LDAP, AMQP, and XMPP/Jabber servers. It simulates user behavior using an XML description file, reports many measurements in real time (statistics can be customized with transactions, and graphics generated using gnuplot). For HTTP, it supports 1.0 and 1.1, has a proxy mode to record sessions, supports GET, POST, PUT, and DELETE methods, cookies, and basic/digest authentication. It also has support for SSL, WebSocket, and BOSH.
The 3Gdb Home Subscriber Server implements the HSS network element within an IP multimedia subsystem (IMS) core network (CN). An IMS CN is a collection of SIP proxies, registrars, and servers used for the provision of services in a 3GPP all-IP mobile network. The HSS provides a centralized data base for subscriber records and generates authentication vectors.
Jingle Nodes is a relay auto-discovery service that provides Jingle Relay Type Candidates that can be used in ICE-UDP and also on RAW-UDP Jingle sessions. Relay candidates can provide NAT traversal for users who don't have STUN/TURN Support, but also for users with STUN/TURN support for whom negotiation failed. It is designed to allow you to communicate freely with your friends without being attached to closed service providers like Skype or telecommunications carriers.
VoltDB is a blazingly fast relational database system. It is specifically designed to run on modern scale-out architectures: fast, inexpensive servers connected via high-speed data networks. It is aimed at a new generation of database applications - real-time feeds, sensor-driven data streams, micro-transactions, low-latency trading systems - requiring database throughput that can reach millions of operations per second. What’s more, the applications that use this data must scale on demand, provide flawless fault tolerance, and enable real-time visibility into the data that drives business value. It includes client application drivers for applications written in Java, C++, C#, PHP, and Python. VoltDB community members have also authored client libraries for Erlang, Ruby and Node.js. There are streaming export capabilities for leading analytic database environments, including Apache Hadoop.
epers stands for "Erlang persistence". As the name suggests, it tries to make it easy to use databases in Erlang programs, to make the language a little more agile, and (humbly) offer a nice adapter for several databases, hiding their implementation details (and the API of the library/framework/driver used to communicate with them). To achieve this, it aims to offer a somewhat consistent API to define and work with your model, while at the same not coupling your code too tightly to it.
Ybot is erlang bot software inspired by Github hubot. It supports IRC and XMPP transports and is extensible with plugins. Plugins can be written with Python, Ruby, or shell. It supports IRC chat, XMPP multi user chat, and 37 signals Campfire chat. It can simultaneously run any number of bots on different transports.
RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is based on a proven platform, Erlang/OTP, offering exceptionally high reliability, availability, and scalability. It delivers good throughput and latency performance that is predictable and consistent. The code base is compact and easily maintainable, facilitating rapid customization and hot deployment. The RabbitMQ distribution also includes a Java client that interoperates with any compliant AMQP server.
ejabberd is a multi-platform, scalable, distributed, and fault-tolerant Jabber/XMPP server. It includes Jabber services like Multi-User Chat, IRC transport, HTTP-Bind, Publish-Subscribe and PEP. It supports virtual hosting, connection to transports (gateways) to other networks, and connection to other Jabber servers. Other supported features are Web and command-line administration, encryption support (SSL and TLS), several authentication methods (embedded, external script, LDAP, PAM, and ODBC), varied storage methods (embedded, ODBC, PostgreSQL, MySQL, MSSQL), Jabber user directory, and translations in more than 20 languages.
