    • An improved system and method for flexible object placement and soft-state indexing of objects in a distributed object store is provided. A distributed object store may be provided by a large number of system nodes operably coupled to a network. A system node provided may include an access module for communicating with a client, an index module for building an index of a replicated data object, a data module for storing a data object on a computer readable medium, and a membership and routing module for detecting the configuration of operable nodes in the distributed system. Upon failure of an index node, the failure may be detected at other nodes, including those nodes that store the replicas of the object. These nodes may then send new index rebuilding requests to a different node that may rebuild the index for servicing any access request to the object.
    • 提供了一种用于灵活对象放置和分布式对象存储中对象的软状态索引的改进的系统和方法。 分布式对象存储可以由可操作地耦合到网络的大量系统节点提供。 提供的系统节点可以包括用于与客户端通信的访问模块,用于构建复制数据对象的索引的索引模块,用于在计算机可读介质上存储数据对象的数据模块,以及用于检测的成员和路由模块 分布式系统中可操作节点的配置。 在索引节点发生故障时,可能会在其他节点(包括存储对象副本的那些节点)中检测到故障。 然后,这些节点可以将新的索引重建请求发送到不同的节点,该节点可以重建用于服务对对象的任何访问请求的索引。

    • A method for synchronizing between an access gateway and a plurality of base stations is provided, which comprises the following steps of: at the gateway, determining (S1) a synchronization period corresponding to a packet to be transmitted to the plurality of base stations, said synchronization period being used as a scheduling granularity of the base stations, adding (S2) information indicating the synchronization period to the header of the packet, and transmitting (S3) the packet to the plurality of corresponding base stations; and at each of the plurality of base stations, obtaining (S4), upon receipt of the packet, the synchronization period corresponding to the packet based on the information in the header of the packet, storing (S5) the packet in a buffer, determining (S6), at the time of scheduling, synchronization periods which have terminated before the time of scheduling based on the synchronization periods corresponding to the stored packets, and scheduling (S7) packets corresponding to the determined synchronization periods according to a predetermined scheduling strategy. A gateway and a base station are also disclosed. The present invention can ensure the synchronization between respective data for individual services received by individual base stations.
    • 提供了一种在接入网关与多个基站之间进行同步的方法,包括以下步骤:在网关处,确定(S1)与要发送给多个基站的分组对应的同步周期,所述 同步周期用作基站的调度粒度,将表示同步周期的信息添加到分组的报头中,并将分组发送到多个对应的基站(S3); 并且在所述多个基站中的每一个处,在接收到所述分组时,基于所述分组的报头中的信息,获得与所述分组对应的同步周期(S4),将所述分组存储在缓冲器中,确定 (S6),在调度时,基于与所存储的分组相对应的同步时段,在调度时间之前终止的同步时段,以及根据预定的调度策略调度(S7)与所确定的同步时段对应的分组。 还公开了网关和基站。 本发明可以确保各个基站接收到的各个服务的各个数据之间的同步。
