The company has developed the a Streaming Component. This component provides authentication, authorization, and charging for mobile streaming clients.
Tenea makes the functional test.

Tenea has defined the Functional Test Plan.

The functional test requires a new tool to check the Streaming Component. This tool might be a standard tool. Normally, the streaming server distribution includes some RTSP clients to check the Streaming Server. Other way might be using the SDK to create a new client, the SDK is included in the streaming server distribution. But unfortunately, the created clients using SDK and the standard clients aren’t enough flexible, these don’t allow checking all the defined requirements for the Streaming Component.

Tenea has designed and developed a new Client to make the test. This client manages the RTSP protocol adding flexibility. It allows changing the behavior of the protocol, introducing mistakes, and getting statistics of the server resources.

Tenea Tecnologías has developed a RTSP Client for Unix. RTSP is the streaming standard protocol for controlling audio-video data such that it can be processed as a steady and continuous stream i.e. no need to download all of the data first. The streaming standards are implemented on IEFT protocol stack:

		RTSP/TCP/IP (Real-Time Streaming Protocol) is used to control the session in a “VCR-like” way.
		RTP/UDP/IP (Real-Time Transport Protocol) is used for the transport of the data. UDP allows fast delivery, no
		retransmissions with the cost of packet loss.
		RTCP/UDP/IP (Real-Time Control Protocol) is used for exchanging information about the ongoing session and
		statistics in order for the stream to adapt itself to core network

The client requires a socket layer. The socket layer will be an abstraction layer for the use of the UNIX Sockets. It has a set of public functions to access to TCP/IP and UDP/IP services. It’s available through interfaces (pure virtual classes). It uses the ACE C++ Wrapper (SOCK_SAP/TLI_SAP).
