A method and apparatus for transmitting data and a method and apparatus for performing a task for process migration are provided. The method of transmitting data includes: determining a data transmission priority using at least one of information relating to data needed to continuously perform a task, that is currently performing, in an external device and information relating to data transmission means; determining transmission methods for each data based on the data transmission priority; and transmitting data to the external device according to the determined transmission methods.

Method and apparatus for transmitting data and method and apparatus for performing data tasks

An apparatus and method are provided for variably transmitting a multimedia stream according to requirements of a client device and the state of a channel. The multimedia stream transmission apparatus includes: a plurality of virtual machines corresponding to the multiple client applications, each of the virtual machines determining a specific parameter set and obtaining a change value for the parameter set from network statistics and a requirement of a corresponding client application; a parameter adjustment unit which adjusts values of parameters used in a network interface by the change value; and the network interface which transmits the multimedia stream based on the adjusted parameters.

Apparatus and method for transmitting multimedia stream using virtual machines based on a number of transmissions at a data rate

A method and apparatus for controlling parameters of a wireless data streaming system are provided. The method of controlling parameters of a wireless data streaming system includes controlling first parameters, which can be controlled in units of individual packets, according to a current packet transmission state in a data stream; transmitting a predefined number of packets using the first parameters and obtaining statistical information regarding use of the first parameters in the transmission of the predefined number of packets; and controlling second parameters, which can be controlled in units of packet groups, with reference to the statistical information and a desired quality of service (QoS).
