摘要
An exemplary embodiment provides for methods, apparatuses and systems to facilitate the detection of network device failures in a variety of network topologies. This is accomplished by equipping a network device, or other devices used in conjunction with network devices, with a bypass port or network interface, such as a secondary outgoing network traffic communication port. In a normal operating mode, network traffic received at a first network interface or port is forwarded, after processing on the packet processing path of the network device, from a second network interface or port. In one implementation, the second network interface or port and the bypass port or network interface are connected to corresponding interfaces of a router or two routers. When a network device failure occurs network traffic bypasses the packet processing path of the network device and is forwarded from the bypass port or interface.
