Abstract: A method for buffering data in an adaptive streaming service according to an embodiment of the present disclosure comprises the steps of: measuring a per-session throughput and an available bandwidth with respect to traffic generated from a streaming application; determining a number of multiple sessions based on the per-session throughput and the available bandwidth; determining a buffer size for pre-storing data based on a cache hit ratio of the streaming application; and generating at least one request message requesting data based on the number of multiple sessions and the buffer size, and transmitting the at least one request message to a server.

Abstract: A method for controlling an upload size of data by a device is provided. The method includes determining whether to change a size of data to be uploaded based on a policy of an upload target server, upon determining to change the size of the data to be uploaded, determining an initial transfer size of the data, and uploading a part of the data corresponding to the determined initial transfer size, updating an upload result of the partial data in an upload history, and determining a next transfer size for the data depending on a reception result of the part of the data from the upload target server for a period obtained from the policy.

Abstract: The present disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method includes acquiring a shared address for at least one file stored at a cloud storage server upon detecting that the at least one file needs to be backed up, determining at least one other cloud storage server to which the at least one file will be backed up, and transmitting a backup request message including the shared address to the at least one other cloud storage server.

Abstract: The disclosure relates to a communication technique for combining a 5th generation (5G) communication system that supports higher data transmission rates after 4th generation (4G) systems with Internet of Things (IoT) technology and to system thereof. The disclosure can be applied for intelligent services based on 5G communication technology and IoT related technology (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety related services, and the like). To do so, a method for providing, by a streaming server, HTTP adaptive streaming to a client terminal is provided. The method includes transmitting a first multimedia data to a terminal, monitoring a network environment between a streaming server and the terminal when the first multimedia data is transmitted to the terminal, and pushing at least one second multimedia data based on the network environment monitored.
