As a new and improved approach to control data transmission of a multi-homed communication device, i.e. a device which has access to multiple different access networks, and to efficiently utilize multiple networks by a plurality of multi-homed communication devices, the invention proposes a. method for dynamic transmission rate control of a communication device, which is connectable to at least two different access networks, having the steps of
a) establishing a data connection between the communication device and a destination node,
b) routing through each of said different access networks a separate data flow associated with said data connection, wherein the transmission rate of each data flow is separately adjustable,
c) estimating for each access network the available bandwidth for data transmission,
d) calculating for each access network a control value depending on the estimated available bandwidth of the respective access network, and
e) adjusting for each of said different access networks the transmission rate for the respective data flow depending on the respective control value. The invention further proposes a communication device and a communication system comprising multiple such communication devices for performing the method. |
