Aplicabilidade do Global Media Transmission Protocol (GMTP)
Abstract
Current Internet live streaming systems require various middlewares as they need specific network services. As a result, this increases network resource consumption as well as it is difficult to implement interoperable live streaming systems. The Global Media Transmission Protocol (GMTP) addresses this problem by proposing a live media distribution protocol for the Internet. GMTP uses P2P algorithms at socket level in order to build a network of favors among cooperative routers. The network of favors is managed by streaming servers, which orchestrate router partnerships based on the capacity of each router transmission channel. This paper presents an applicability study of GMTP by implementing GMTP in a real Operating System and assessing GMTP deployment and performance.
