Exchanging media stream data between thin client and media gateway, bypassing virtual machine, in cloud computing system

A method for transmitting media stream data in a cloud computing system, comprising:

• obtaining, by a corresponding virtual machine (VM), media stream transmission information of a thin client (TC) from the TC, wherein the cloud computing system comprises a physical server on which the VM runs, and wherein the TC logs in to the VM;
• and
• sending, by the VM, the media stream transmission information of the TC to a media gateway and sending obtained media stream transmission information of the media gateway to the TC such that the TC establishes a session between the TC and the media gateway according to the media stream transmission information of the TC and the media stream transmission information of the media gateway, and transmits media stream data by using the established session,
• wherein the media stream transmission information of the TC comprises media stream address information of the TC, or the media stream address information of the TC and media stream codec information supported by the TC, and wherein the media stream transmission information of the media gateway comprises the media stream address information of the media gateway, or the media stream address information of the media gateway and the media stream codec information supported by the media gateway.

A thin client (TC) in a cloud computing system, comprising:

• a registering unit configured to send media stream transmission information of the TC to a corresponding virtual machine (VM) such that the VM sends the media stream transmission information of the TC to a media gateway, wherein the cloud computing system comprises a physical server on which the VM runs, and wherein the TC logs in to the VM;
• a receiving unit configured to receive the media stream transmission information of the media gateway from the VM;
• and
• a transmitting unit configured to establish a session between the TC and the media gateway according to the media stream transmission information of the TC and the media stream transmission information of the media gateway, and transmit media stream data by using the established session,
• wherein the media stream transmission information of the TC comprises media stream address information of the TC, or the media stream address information of the TC and media stream codec information supported by the TC, and wherein the media stream transmission information of the media gateway comprises the media stream address information of the media gateway, or the media stream address information of the media gateway and the media stream codec information supported by the media gateway.

A virtual machine (VM) in a cloud computing system, comprising:

• a registering unit configured to obtain media stream transmission information of a thin client (TC) from the TC, wherein the cloud computing system comprises a physical server on which the VM runs, and wherein the TC logs in to the VM;
• and
• a sending unit configured to send the media stream transmission information of the TC to a media gateway and send obtained media stream transmission information of the media gateway to the TC such that the TC establishes a session between the TC and the media gateway according to the media stream transmission information of the TC and the media stream transmission information of the media gateway, and transmits media stream data by using the established session,
• wherein the media stream transmission information of the TC comprises media stream address information of the TC, or the media stream address information of the TC and media stream codec information supported by the TC, and wherein the media stream transmission information of the media gateway comprises the media stream address information of the media gateway, or the media stream address information of the media gateway and the media stream codec information supported by the media gateway.
