Application scheduling method, device and system based on packet scheduling

The embodiment of the invention provides an application scheduling method, device and system based on packet scheduling. In the application scheduling method based on packet scheduling, an application scheduling request from a client is received, and the application scheduling request comprises description information used for indicating a chained calling relation between to-be-scheduled applications; according to the chained calling relation, the to-be-scheduled applications are divided into at least one scheduling object group, and the to-be-scheduled applications in the same scheduling object group have the same chained calling relation; and scheduling each to-be-scheduled application to the target node by taking the scheduling object group as a unit. 本说明书的实施例提供了一种基于分组调度的应用调度方法、装置和系统。在该基于分组调度的应用调度方法中，接收来自客户端的应用调度请求，其中，所述应用调度请求包括用于指示各个待调度应用之间的链式调用关系的描述信息；根据所述链式调用关系，将各个待调度应用分入至少一个调度对象组，其中，位于同一调度对象组内的待调度应用具有同一链式调用关系；以及以调度对象组为单位，将各个待调度应用调度至目标节点。
