Abstract: A first reverse proxy appliance of the plurality of reverse proxy appliances receives an incoming transaction. A machine logic determines that the incoming transaction cannot be directly processed by the first reverse proxy appliance based, at least in part, upon the current threshold level of the first reverse proxy appliance and the current transaction count of the first reverse proxy appliance. Responsive to the determination that the incoming transaction cannot be directly processed by the first reverse proxy appliance, a second reverse proxy appliance of the plurality of reverse proxy appliances and a third reverse proxy appliance of the plurality of reverse proxy appliances negotiate in order to determine that the third reverse proxy appliance will process the incoming transaction. Responsive to the negotiating, the incoming transaction is sent to the third reverse proxy appliance.

Abstract: A receiver includes a control module, a data receiving circuit and a masking circuit. The control circuit generates an enable signal according to a pair of differential signals provided by a transmitter. Triggered by the enable signal, the data receiving circuits generates an output signal according to the differential signals, and the masking circuit starts masking the output signal. After generating the enable signal, the control module starts providing a bias voltage to the differential signals such that the output signal has a first state. The transmitter adjusts the differential signals to render the output signal to enter a second state from the first state. Upon detecting the output signal having entered the second state, the control module stops providing the bias voltage and generates a disable signal to prompt the masking circuit to stop masking the output signal.
