    • An Ethernet transmission apparatus having a quick protection and fair attribute as well as a corresponding method are disclosed. The apparatus comprises a sorter, MPLS processing module and a SDH processing module, wherein, the MPLS processing module includes a VC tag packaging unit, a multiplexing unit, a tag managing unit, a scheduler, an MPLS protective unit, an MPLS signaling unit and a Fair algorithm unit. The present invention sorts the Ethernet transactions and labels VC tags by the VC tag packaging unit so as to form a PW LSP. PW LSP with a plurality of identical source and target ends are multiplexed into a tunnel LSP. MPLS signaling unit counts the network nodes that LSP passes by and calculates a protective LSP. MPLS protective unit selects an active LSP or a protective LSP and enters the scheduler for queuing. The FAIR algorithm controls the allotment of the bandwidth so as to secure the fairness of the transactions.
    • 公开了具有快速保护和公平属性的以太网发送装置以及相应的方法。 该装置包括分类器,MPLS处理模块和SDH处理模块,其中,MPLS处理模块包括VC标签封装单元,复用单元,标签管理单元,调度器,MPLS保护单元,MPLS信令单元和 一个公平的算法单元。 本发明通过VC标签封装单元对以太网事务进行分类并标注VC标签,形成PW LSP。 具有多个相同的源和目标端的PW LSP被复用到隧道LSP中。 MPLS信令单元对LSP通过的网络节点进行计数,并计算保护LSP。 MPLS保护单元选择主动LSP或保护LSP,进入调度器进行排队。 FAIR算法控制带宽的分配,以确保交易的公平性。

    • An air treatment device includes a housing, a filter element disposed in the housing, an air forcing device for forcing air to flow through the filter element, and a light device disposed in front of the filter element for generating light and for germ killing purposes. The housing includes a pressurized compartment formed between the filter element and the air forcing device, to receive the light device. An ozone generator may supply ozone through the filter element for germ killing purposes. An oxygen generator may supply oxygen out of the housing and into the environment of the users. A filter member may be used for filtering purposes, and a tray disposed below the filter member to collected filtered materials.
    • 空气处理装置包括壳体,设置在壳体中的过滤元件,用于迫使空气流过过滤元件的空气迫使装置,以及设置在过滤元件前面用于产生光和用于灭菌的光装置。 壳体包括形成在过滤元件和空气迫使装置之间的加压隔室,用于接纳灯装置。 臭氧发生器可以通过过滤元件供应臭氧以用于灭菌目的。 氧气发生器可以将氧气从壳体中供应到用户的环境中。 过滤器构件可以用于过滤目的,以及设置在过滤构件下方以收集过滤材料的托盘。
