1. An access request scheduling method, implemented by one or more processors, comprising:
determining a city and a city operator corresponding to an access source IP segment;
selecting, from cloud delivery nodes of the city operator, a preferred node of the access source IP segment;
determining a mapping relationship between the access source IP segment and an IP of the preferred node;
issuing the mapping relationship to scheduling agent modules of the cloud delivery nodes in a network; and
after a current cloud delivery node of the cloud delivery nodes receives a user's access request, scheduling, by the scheduling agent module of the current cloud delivery node, the user's access request according to the mapping relationship, including:
determining an access source IP segment to which a source IP in the user's access request belongs;
querying for the IP of the preferred node corresponding to the access source IP segment according to the mapping relationship;
judging whether the current cloud delivery node is the preferred node;
returning an access response in response to the current cloud delivery node being the preferred node; and
returning the IP of the preferred node to indicate a redirection operation in response to the current cloud delivery node being not the preferred node.
