    • An approach provides a communication network that supports one or more network-based Virtual Private Networks (VPNs) to resist Denial of Service (DoS) attacks. A first boundary router is configured to provide a Virtual Private Network (VPN) that supports quality of service levels, and interfaces an access network via a Customer Premise Equipment (CPE) edge router and a physical access link. A second boundary router is coupled to a public network. The access network connects to the first boundary router, and wherein the first boundary router and the second boundary router are connected by a separate logical connection to prevent denial of service attacks on the physical access link originating from sources outside the VPN.
    • 一种方法提供了支持一个或多个基于网络的虚拟专用网(VPN)来抵御拒绝服务(DoS)攻击的通信网络。 第一边界路由器被配置为提供支持服务质量水平的虚拟专用网(VPN),并且经由客户端设备(CPE)边缘路由器和物理接入链路来接入接入网络。 第二边界路由器耦合到公共网络。 所述接入网络连接到所述第一边界路由器,并且其中所述第一边界路由器和所述第二边界路由器通过单独的逻辑连接来连接,以防止对源自所述VPN外的源的物理接入链路的拒绝服务攻击。

    • An approach for providing network security is disclosed. The system includes a first set of routing devices (e.g., routers, routing switches, etc.) operating redundantly within an autonomous system. The system also includes a second set of routing devices that are configured for redundant operation within the autonomous system and to communicate with another autonomous system. The sets of routing devices provide a communication path between the autonomous systems for transport of untrusted packets and trusted packets. Further, the system includes a security node (i.e., weighstation) configured to communicate with the sets of routing devices and to only receive the untrusted packets, wherein the untrusted packets are selectively forwarded to the other autonomous system.
    • 公开了一种提供网络安全的方法。 该系统包括在自主系统内冗余地操作的第一组路由设备(例如,路由器,路由交换机等)。 该系统还包括第二组路由设备,其被配置用于在自主系统内的冗余操作并且与另一自主系统通信。 这些路由设备组在自治系统之间提供用于传输不可信包和可信包的通信路径。 此外,该系统包括被配置为与该组路由设备进行通信并且仅接收该不可信分组的安全节点(称重站),其中该不可信分组被选择性地转发到另一个自主系统。
