Attempts to display media on computers date back to the earliest days of computing in the mid-20th century. However, little progress was made for several decades, primarily due to the high cost and limited capabilities of computer hardware. From the late 1980s through the 1990s, consumer-grade personal computers became powerful enough to display various media. The primary technical issues related to streaming was having enough CPU power and bus bandwidth to support the required data rates and creating low-latency interrupt paths in the operating system (OS) to prevent buffer under run. However, computer networks were still limited, and media was usually delivered over non-streaming channels, such as by downloading a digital file from a remote server and then saving it to a local drive on the end user's computer or storing it as a digital file and playing it back from CD-ROMs. The challenges of new communication architecture are to offer better quality of service (QoS) in internet Network. A large diversity of services based on packet switching in 3G network and beyond 3G leads dramatic changes in the characteristics and parameter of data traffic. Through this paper we propose a streaming solution to offer better QoS over 3G and 4G networks. A comparative analysis of HTTP streaming and RTP streaming has been done and packet loss, average bandwidth utilization and total streaming time has been measured. Result shows RTP provides better quality of service over HTTP for multimedia based content transfer over various network. Simulation is done using Java Media Framework.
