Abstract: Some embodiments provide a novel method for distributing control-channel communication load between multiple controllers in a network control system. In some embodiments, the controllers manage physical forwarding elements that forward data between several computing devices (also called hosts or host computers), some or all of which execute one or more virtual machines (VMs). The method of some embodiments distributes a controller assignment list to the host computers. The host computers use this list to identify the controllers with which they need to interact to perform some of the forwarding operations of their associated logical forwarding elements. In some embodiments, agents executing on the host computers (1) review the controller assignment list to identify the appropriate controllers, and (2) establish control channel communications with these controllers to obtain the needed data for effectuating the forwarding operations of their associated physical forwarding elements.

Abstract: A low-dropout regulator with super transconductance structure relates to the field of power management technology. The super-transconductance structure refers to the circuit structure in which the voltage signal is converted into a current signal and amplified with a high magnification. The error amplifier EA in the present invention uses the super transconductance structure. The differential input pair of the error amplifier EA samples the difference between the feedback voltage VFB and the dynamic reference voltage VREF1. The difference is converted into a small signal current, which goes through a first-stage of current mirror to be amplified by K1, and through a second-stage of current mirror to be amplified by K2. The amplified signal is used to regulate the gate of the adjustment transistor MP. The error amplifier EA with the super transconductance structure is used to expand the bandwidth of the error amplifier EA.
