Abstract
According to one embodiment of the invention, there is provided a data communication device for processing a data stream, including a runtime virtual machine (VM) and a mirror VM. The two VMs are independently running on the same physical hardware of the data communication device. The runtime VM is operable for receiving the data stream and establishing a plurality of data links to process the data stream. The mirror VM is operable for backing up the data links established by the runtime VM. The data stream is switched from the runtime VM to the mirror VM for processing if a predetermined condition occurs in the runtime VM.
