A method and apparatus for calculating the blood flow rate in a coronary artery, an electronic device and a storage medium. The method for calculating the blood flow rate in a coronary artery comprises the following steps: S, acquiring an angiography image of the coronary artery, segmenting the angiography image of the coronary artery by using deep learning, and obtaining segmented images of a main vessel (S); S, calculating the length of the main vessel in each segmented image frame on the basis of the segmented images of the main vessel (S); and S, obtaining the blood flow rate in the main vessel on the basis of the calculated change of the lengths of the main vessel with time (S). By using the method and apparatus for calculating the blood flow rate in a coronary artery and the electronic device, the automation of the calculation of the blood flow rate in a coronary artery is achieved, the calculated blood flow rate in the coronary artery is more accurate, and the calculation method is simple.

Techniques are generally directed to selective reestablishment of Internet Protocol (IP) connectivity between a cable modem and a cable modem termination system (CMTS). IP connectivity between the cable modem and the CMTS is initially established through execution of a plurality of connectivity steps. After IP connectivity is lost, the cable modem determines which of the plurality of connectivity steps are desired for use in reestablishing IP connectivity, and sends a message to the CMTS indicating the desired IP connectivity step. The CMTS determines if the desired connectivity steps identified in the message may be used to reestablish IP connectivity, and sends a response message to the cable modem indicating if the desired connectivity steps may be used. IP connectivity is then reestablished using at least the desired connectivity steps.
