    • This invention relates to a method, device and system for providing and selecting candidate nodes for live streaming services. According to one aspect of the invention, the method for providing a candidate nodes list for live streaming services, which comprises: collecting information of each node involved in the live streaming services; based on the collected information, calculating progress factors of each node; comparing the collected information of each node with load thresholds; sorting the nodes, the collected information of which are below the load thresholds, on the basis of the calculated progress factors; and forming the candidate nodes list by a number N of first N nodes of the sorted nodes. According to the other aspect of the invention, the method for selecting a candidate node for live streaming services comprises: based on information involved in the live streaming services, calculating progress factors; reporting the calculated progress factors and requesting for candidate nodes list; selecting a candidate node from the candidate nodes list according to delay requirements and policies for overlay of the live streaming services.
    • 本发明涉及一种用于提供和选择用于直播流服务的候选节点的方法,设备和系统。 根据本发明的一个方面,提供一种用于直播流服务的候选节点列表的方法,包括:收集直播流服务中涉及的每个节点的信息; 根据收集的信息,计算每个节点的进度因子; 将每个节点收集的信息与负载阈值进行比较; 根据计算出的进度因素对收集的信息进行排序,收集的信息低于装载阈值; 以及通过排序节点的前N个节点的数目N形成候选节点列表。 根据本发明的另一方面,用于选择用于实况流服务的候选节点的方法包括:基于实况流服务中涉及的信息,计算进度因子; 报告计算出的进度因子并请求候选节点列表; 根据延迟要求和实时流媒体业务覆盖策略,从候选节点列表中选择候选节点。
