Abstract
Data packets are communicated between a transmitting virtual router in a transmitting computer device and a receiving virtual router in a receiving computer device. A security association is established for the secure transmission of data packets between the transmitting computer device and the receiving computer device. The transmitting virtual router and the receiving virtual router are identified within said security association. In the transmitting computer device, the security association for processing a data packet coming from the transmitting virtual router is selected on the basis of the identification of the transmitting virtual router within the security association. In the receiving computer device, the security association for processing a data packet coming from the transmitting computer device is selected on the basis of values contained within the data packet. In the receiving computer device, the data packet processed within the security association is directed to the receiving virtual router on the basis of the identification of the receiving virtual router within the security association.
