Scheduling user requests in a distributed resource system having plurality of schedulers and coordinators

摘要

According to a method for scheduling a user request in a distributed resource system, an apparatus, and a system that are provided by embodiments of the present invention, in a T_n+1 period, an S_d acquires, from a coordinator G_k of a user z, a resource C_z(T_n) that is consumed by a user z request in a T_n period, and the S_d schedules, according to ϕ_z, C_z(T_n), C_z,d(T_n), and N_z,d(T_n), a Pⁱ_z,d by using a scheduling algorithm. The user z request can be scheduled without depending on a user agent. In addition, the S_d schedules, according to ϕ_z, C_z(T_n), C_z,d(T_n), and N_z,d(T_n), the Pⁱ_z,d by using the scheduling algorithm, thereby implementing global scheduling on the user z request and ensuring a performance requirement of the user z.
