摘要： A method for sending a data packet includes, sending, by a transmit node, a data packet based on a target sending rate and occupation of a data sending queue, where a sending rate for sending the data packet is proportional to the target sending rate, and the occupation of the data sending queue limits a quantity of data packets. The transmit node receives a feedback message from a receive node indicating the capability of the receive node for processing the data packet. The transmit node may adjust the sending rate based on the feedback message.

摘要： Aspects of the present disclosure are presented for providing coordinated energy outputs of separate but connected modules, in some cases using communication protocols such as the Data Distribution Service standard (DDS). In some aspects, there is provided a communication circuit between a header or main device, a first module, and a second module, each including connection to a segment of a common backplane, where the output from a first module can be adjusted by sensing a parameter from a second module. In some aspects, the signal can pass from the first module through the header to the second module, or in other cases directly from the first module to the second module. Aspects of the present disclosure also include methods for automatically activating a bipolar surgical system in one or more of the modular systems using the DDS standard.
