    • In one aspect, a disclosed method of processing a network packet received by an edge device from a client in a data processing network includes determining a priority category of the network packet when the priority category is indicative of a priority associated with the packet. The method further includes determining a value of a traffic state parameter. The traffic state parameter indicates a level of traffic activity in a backbone network to which the edge device is connected. A traffic policy is then determined that is applicable to the level of traffic activity and the priority category of the network packet. The network packet is then blocked from traversing or permitted to traverse the network packet edge device based on the determined traffic policy. Determining the priority category may include determining a transport protocol port number of the network packet.
    • 在一个方面,一种公开的处理由边缘设备从数据处理网络中的客户端接收的网络分组的方法包括当优先级类别指示与分组相关联的优先级时确定网络分组的优先级类别。 该方法还包括确定业务状态参数的值。 流量状态参数表示边缘设备连接到的骨干网络中的流量活动级别。 然后确定适用于网络分组的流量活动级别和优先级类别的流量策略。 然后基于所确定的流量策略,阻止网络分组穿越或允许网络分组边缘设备穿越网络分组边缘设备。 确定优先级类别可以包括确定网络分组的传输协议端口号。

    • Responsive to receiving an authentication request from a device, an authentication server determines a confidence level for the authentication request, generates a confidence-weighted challenge to the authentication request. The confidence-weighted challenge being weighted based upon a confidence level. The authentication server, responsive to receiving a challenge response to the confidence-weighted challenge from the device, determines whether to authenticate the user based upon the challenge response. If the authentication server determines that the challenge response satisfies an expected response known to the authentication server, the authentication server permits authentication of the user to access the device. If the authentication server determines the challenge response does not satisfy the expected response known to the authentication server, the authentication server denies authentication of the user to access the device.
    • 响应于从设备接收认证请求,认证服务器确定认证请求的置信度,对认证请求生成置信加权质询。 基于置信水平加权的置信加权挑战。 认证服务器响应于从设备接收到对置信加权挑战的挑战响应,基于挑战响应确定是否验证用户。 如果认证服务器确定质询响应满足认证服务器已知的预期响应,则认证服务器允许用户认证访问设备。 如果认证服务器确定质询响应不满足认证服务器已知的预期响应,则认证服务器拒绝用户对该设备的认证。
