A Free Software Streaming-Video Application based on MMTP

At higher taxes, MMTP works exactly as UDP protocol, as it was expected.However, with lower taxes MMTP shows better performance. It is still necessary to saythat this test was done without any kind of traffic, which would decrease drastically thenumber of delivered packets by UDP.We now are improving a test bed with a sub-network working with trafficgenerator for the next tests. Another work is to create the same application using theRTP (Real Time Protocol) [6] instead of the MMTP. A related work was done in agraduation work [15] with better results for the MMTP, when comparing both protocols.However, they transmitted only assorted data (not video frames with priority levels) andwithout any traffic generator.A free video streaming application has many interesting uses. MMTP is wellsuited as the transport protocol for such application, even when used in a differentenvironment that it was designed to work. By creating a tool to generate formal protocoldefinitions, we expect to make future changes to existing protocols easier, and be able todesign protocols for specific applications, without having to make the application fit theexisting protocols.5.
