Abstract
Legacy Multimedia Messaging Service (MMS) Environment doesn?t consider transmitting streaming data when many users demand simultaneously. MMS relay/server and streaming server have been overloaded to transmit streaming data continuously to users simultaneously. Therefore its networks and MMS relay performance may go down and additional delay of streaming data occurs. Consequently, the uninterrupted delivery cannot be provided to users requiring high-quality service. In order to provide streaming service efficiently, we propose the optimal connection mechanism using the MMS proxy and the Coordination Agent (CA) in MMS environment. MMS proxies are responsible for users? requests and the CA is used to select the optimal MMS proxy among all the proxies. So, the CA has the list table about the state of proxies and updates it to keep accurate state information about proxies. On the client side, Retransmission should take place before the starvation occurs. So, client regards retransmission as a fault in the proxy when streaming data is not received from the MMS proxy before the starvation. The client should request the CA information on another MMS proxy.
