Request scheduling method, system, device and electronic equipment

The embodiment of the invention provides a request scheduling method, a system, a device and electronic equipment, and the method comprises the steps: receiving an access request of a user for a firstdomain name; in response to the access request, determining a target scheduling domain name according to the scheduling weight of each domain name in a first equivalent domain name group, and each domain name in the first equivalent domain name group can provide service provided by the first domain name; and scheduling an access request for the first domain name to a service node corresponding tothe target scheduling domain name. According to the method, the target scheduling node is determined according to the scheduling weight of each domain name in the equivalent domain name group, and the service state of the service node corresponding to each domain name is considered, so that the accuracy of request scheduling is improved, the problem that resource services cannot be accessed due to faults of a single servi
