Abstract: A control circuit and method for a bleeder, a chip, and a driver system. The bleeder control circuit is connected to a dimmer detector used for detecting the presence or absence of a dimmer and a type of the dimmer. The control circuit of the bleeder is used to receive a detection signal outputted by the dimmer detector, and generate a control signal for the bleeder according to the detection signal, the control signal is used to control an operating state of the bleeder.

Abstract: A novel method for troubleshooting a logical network is provided. The logical network has logical forwarding elements operating inside virtual network forwarding engines. The method receives a source identifier and a destination identifier that correspond to nodes in the logical network. The method then retrieves a set of network data from a virtual network forwarding engine and identifies a path in the logical network by traversing the logical network according to the retrieved set of network data. This traversal starts at an initial network node that is identified by the source identifier and continues through a set of next-hop network nodes that are each identified based on the destination identifier. At least some of the network nodes are logical ports associated with logical forwarding elements implemented by the virtual network forwarding engine. The method then reports the set of traversed logical nodes.

Abstract: Some embodiments provide a method for an MFE, in a first datacenter, to implement an LN spanning the first datacenter and a set of additional datacenters. The method stores records that each map one or more LN addresses for DCNs belonging to the LN and operating in the first datacenter to a different TEP address.
