    • A method for expanding a cluster system is provided. The cluster system includes at least one Cluster Central Chassis (CCC), and a newly-added Cluster Line-card Chassis (CLC) connected with the CCC to form the cluster system. The method includes the following steps. A control plane is established. An equipment management right is switched to the CCC, so that the CCC manages the newly-added CLC. Meanwhile, a cluster line-card device, a cluster central exchange device, and a cluster system are further provided. In implementation, smooth expansion can be achieved without interrupting running equipment services in the CLC current network and without interrupting data services. Moreover, during the expansion process, hardware equipment needs not to be replaced, thus investment of users on the equipment is reduced.
    • 提供了一种用于扩展集群系统的方法。 集群系统包括至少一个集群中心机箱(CCC)和与CCC连接的新增的集群线路卡机箱(CLC),以形成集群系统。 该方法包括以下步骤。 建立一个控制平面。 设备管理权转用CCC,CCC管理新增的CLC。 同时,还提供集群线路卡设备,集群中央交换设备和集群系统。 在实施中,可以实现平滑扩展,而不会中断CLC当前网络中的运行设备服务,而不会中断数据服务。 此外,在扩展过程中,硬件设备不需要更换,用户对设备的投资减少。

    • A network device includes a plurality of blades, each having a plurality of CPU cores that process requests received by the network device. Each blade further includes an accumulator circuit. Each accumulator circuit periodically aggregates the local counter values of the CPU cores of the corresponding blade. One accumulator circuit is designated as a master, and the other accumulator circuit(s) are designated as slave(s). The slave accumulator circuits transmit their aggregated local counter values to the master accumulator circuit. The master accumulator circuit aggregates the sets of aggregated local counter values to create a set of global counter values. The master accumulator circuit transmits the global counter values to a management processor (for display), to the CPU cores located on its corresponding blade, and to each of the slave accumulator circuits. Each slave accumulator circuit then transmits the global counter values to the CPU cores located on its corresponding blade.
    • 网络设备包括多个刀片,每个刀片具有处理由网络设备接收的请求的多个CPU内核。 每个叶片还包括一个蓄电池电路。 每个累加器电路周期性地聚集相应刀片的CPU内核的本地计数器值。 一个累加器电路被指定为主机,另一个累加器电路被指定为从机。 从累加器电路将其聚合的本地计数器值发送到主累加器电路。 主累加器电路聚合本地计数器值集合以创建一组全局计数器值。 主累加器电路将全局计数器值发送到管理处理器(用于显示),发送到位于其相应刀片上的CPU核心以及从属累加器电路中的每一个。 然后,每个从属累加器电路将全局计数器值发送到位于其相应刀片上的CPU核心。
