Abstract
A method for routing a packet. The method includes receiving the packet from a first network into a network interface card (NIC), where the NIC is operatively connected to a host and the host includes a first virtual network stack and a second virtual network stack. The method further includes sending the packet to a first virtual network stack, where the first virtual network stack includes a first filter, a first network layer, and a first transport layer. In addition, the first filter, the first network layer, and the first transport layer are isolated from the second virtual network stack. If the packet is permitted through the first filter in the first virtual network stack, then the packet is sent to a first virtual NIC.
