Patent number: 8111690Abstract: Methods and systems are provided for routing traffic through a virtual router-based network switch. According to one embodiment, a flow data structure is established that identifies current packet flows associated with multiple virtual routers in the virtual router-based network device. When an incoming packet is received by the virtual router-based network device, it is then determined whether the incoming packet is associated with a current packet flow by accessing the flow data structure based on a header associated with the incoming packet. If it is determined that the incoming packet is associated with the current packet flow, then the incoming packet is hardware forwarded via a network interface of the virtual router-based network device without intervention by a processor of the virtual router-based network device, otherwise the incoming packet is forwarded to software on the processor for flow learning.Type: GrantFiled: October 29, 2008Date of Patent: February 7, 2012Assignee: Google Inc.Inventors: Zahid Hussain, Samir Jain, Naveed Alam, Joseph Cheng, Greg Lockwood, Tim Millet
