    • The present invention discloses a method for implementing packet forwarding control in routing device, comprising: said routing device getting a source address of a received packet and judging whether said source address is a legal source address; if it is a legal source address, confirming said packet to be a legal packet, and processing said packet with a normal process flow, and otherwise, confirming said packet to be an illegal packet and proceeding to Step b; and said routing device implementing forwarding control for said packet. The present invention solves the problems in the prior art when controlling packet forwarding, such as resource occupation and degradation of processing capability of network communication devices caused by adding data structures or increasing system overheads. The present invention provides a method for controlling packet forwarding, saving the resource of network communication equipment, improving the processing ability of the network communication equipment, and enhancing the security of the network.
    • 本发明公开了一种在路由设备中实现分组转发控制的方法,包括:所述路由设备获取接收到的分组的源地址,并判断所述源地址是否为合法的源地址; 如果是合法的源地址,则确认所述分组为合法分组,并以正常的进程流处理所述分组,否则确认所述分组为非法分组,并进行步骤b; 并且所述路由设备对所述分组实现转发控制。 本发明解决了现有技术中控制分组转发的问题,例如资源占用以及通过添加数据结构或增加系统开销而引起的网络通信设备的处理能力的下降。 本发明提供一种控制分组转发的方法,节省了网络通信设备的资源,提高了网络通信设备的处理能力,提高了网络的安全性。

    • An over-current protection device comprises a chemically cross-linked positive temperature coefficient (PTC) layer and two electrode foils that can be connected to a power source to allow current to flow through the chemically cross-linked polymeric PTC layer. The chemically cross-linked polymeric PTC layer comprises at least two different PTC polymer layers, and each polymer layer comprises polymer and conductive filler and has a volumetric resistivity between 10−1 and 10−3 Ω-cm. The polymer layers have different functional groups and are alternately stacked and hot pressed to generate chemical cross-linking therebetween so as to form the chemically cross-linked polymeric PTC layer, wherein the potential difference of every 0.1 mm in thickness of the chemically cross-linked polymeric PTC layer is less than 30 volts.
