Estimating the term…
Network devices that are inserted inline into network links and process in-transit packets may significantly improve their packet-throughput performance by not assigning L3 IP addresses and L2 MAC addresses to their network interfaces and thereby process packets through a logical fast path that bypasses the slow path through the operating system kernel. When virtualizing such Bump-In-The-Wire (BITW) devices for deployment into clouds, the network interfaces must have L3 IP and L2 MAC addresses assigned to them. Thus, packets are processed through the slow path of a virtual BITW device, significantly reducing the performance. By adding new logic to the virtual BITW device and/or configuring proxies, addresses, subnets, and/or routing tables, a virtual BITW device can process packets through the fast path and potentially improve performance accordingly. For example, the virtual BITW device may be configured to enforce a virtual path (comprising the fast path) through the virtual BITW device.
A cloud computing network configured to send packets between a network address translation (NAT) gateway and a second virtual device, via a virtual bump-in-the-wire (BITW) device, the cloud computing network comprising:
A non-transitory computer-readable medium storing instructions that, when executed by one or more processors of a cloud computing network, cause the cloud computing network to send packets between a network address translation (NAT) gateway and a second virtual device, via a virtual bump-in-the-wire (BITW) device, by:
A method comprising:
A method for sending packets in a virtual private cloud network between a network address translation (NAT) gateway and a second virtual device, via a virtual bump-in-the-wire (BITW) device, the method comprising:
