    摘要: Some embodiments of the invention provide a method of tunneling a data packet by encapsulating the data packet with a protocol header and specifying information in the fields of the header in a manner that a network switch can offload processing tasks to its network interface controller. The switch on a transmit side sends the processed data packet through the tunnel to another switch on a receive side. The two sides represent the two ends of the tunnel established between the two switches. Each of the transmit and received side switches is controlled by a switch controller, which in some embodiments is implemented as software. The switch controllers and network interface controllers together process the data packet which is being transferred through the tunnel between the switches.

    摘要: For a managed network including first and second managed switching elements that implement logical data path sets, some embodiments provide a method that establishes, from the first managed switching element, a network tunnel through a network to the second managed switching element. The network includes a set of unmanaged switching elements. Through the network tunnel, the network forwards logical network data to the set of unmanaged switching elements for the set of unmanaged switching elements to forward to the second managed switching element. The logical network is hidden from the set of unmanaged switching elements when the logical network data is forwarded through the tunnel.
