    Abstract: A system and method for migrating a guest bridge are provided. An example method includes maintaining at a guest bridge a set of forwarding tables including a set of mappings from a network address to at least one virtual network interface of a set of virtual network interfaces. The method includes receiving at the guest bridge a notification that the guest bridge has migrated to a target host machine. The target host machine includes a set of physical network interfaces, and each physical network interface of the set of physical network interfaces is coupled to a network. The method further includes responsive to the notification, updating the set of forwarding tables.

    Abstract: A system and method can support dynamic provisioning in a network switch environment, such as supporting virtualized switch classification tables in a network switch. The system can provide a plurality of memory blocks that can be used to build one or more classification tables for supporting packet processing. Furthermore, the system can comprise a management entity that operates to monitor traffic profile associated with a network port in the network switch. Then, the management entity can allocate one or more memory blocks in the plurality of memory blocks for a logical classification table, and associate the logical classification table with the network port.

    Abstract: A network controller for managing several managed switching elements that forward data in a network that includes the managed switching elements. The network controller is further for creating a logical switching element to be implemented in a set of managed switching elements. The network controller includes a set of modules for receiving input data specifying a logical switching element and for creating, based on the received input data, a set of logical switch constructs for the logical switching element by performing a set of database join operations. At least one of the logical switch constructs is for facilitating non-forwarding behavior of the logical switching element.

    Abstract: A congestion notification system includes a networking device coupling a sender device to a receiver device. The networking device is configured to detect a congestion situation. When the networking device will provide a first congestion notification in a first packet received from the sender device in response to detecting the congestion situation, as well as retrieve sender device information from the first packet and store that sender device information in a database. Following the sending of the first packet to the receiver device, the networking device receives a second packet that was sent from the receiver device prior to the receiver device receiving the first packet. In response to determining that the second packet includes the sender device information that is stored in the database, the networking device provides a second congestion notification in the second packet. The networking device then sends the second packet to the sender device.
