摘要： In one embodiment, a Home Agent receives a Mobile IP registration request from a group member, where the group member is a Mobile Node. The Home Agent generates a mobility binding for the group member that associates the group member with a care-of address, wherein the group member is a member of one or more groups. The Home Agent generates a Mobile IP registration reply, where the Mobile IP registration reply identifies one or more key servers. Each of the one or more key servers serves at least one of the one or more groups and is adapted for distributing group cryptography material to members of each group that is served by the corresponding key server. The Home Agent sends the Mobile IP registration reply to the group member, thereby enabling the group member to obtain cryptography material for at least one of the one or more groups from at least one of the one or more key servers to enable the group member to use the cryptography group material to securely communicate with other group members.

摘要： One embodiment provides a method to interconnect virtual network segments (VNETs) defined for a local-area network (LAN) infrastructure separated by a wide-area network infrastructure. The technique involves the routing device at the LAN-WAN interconnection points to impose or dispose the VNET-shim, which encodes the VNET-id information in a Layer 4 portion of the packet. In a data plane, a new IP protocol value may be used to signify the presence of the VNET-shim followed by cryptography specific information in an IP packet. In a control plane, the routing protocol is expanded to exchange the routing information along with the VNET information.
摘要翻译：一个实施例提供了一种互连为由广域网基础设施分开的局域网（LAN）基础设施定义的虚拟网段（VNET）的互连方法。该技术涉及LAN-WAN互联点处的路由设备，以对VNET-shim进行处理或配置，VNET-shim将数据包的第4层部分中的VNET-id信息编码。在数据平面中，可以使用新的IP协议值来表示VIP-shim的存在，随后是IP分组中的加密特定信息。在控制平面中，路由协议被扩展以便与VNET信息一起交换路由信息。

摘要： An apparatus for limiting Virtual Private Network (VPNv4) prefixes per VPN in an inter-autonomous system environment are presented. A limit on the number of VPNv4 routes per VPN for a Route Distributor (RD) or a group of RDs associated with a VPN is defined, at an Autonomous System Border Router (ASBR). When the number of received routes at the ASBR exceeds the limit, then a soft notification is sent to a neighboring ASBR and routes exceeding the limit are discarded at the ASBR.
摘要翻译：提出了一种用于在自主系统环境中限制每个VPN的虚拟专用网（VPNv4）前缀的装置。在自治系统边界路由器（ASBR）上定义了路由分配器（RD）或与VPN相关联的一组RD的每个VPN的VPNv4路由数量的限制。当ASBR接收到的路由数超过限制时，会向邻近的ASBR发送软通知，并在ASBR上丢弃超过限制的路由。

摘要： A method, apparatus and computer program product for providing an encrypted multipoint Virtual Private Network (VPN) service is presented. A first packet of a plurality of packets is received at an ingress provider edge (PE) the plurality of packets destined for a remote server in communication with said egress PE router. A lookup for a destination prefix of a first packet is preformed, and a determination made that a next-hop for the first packet is reachable through a mGRE tunnel. A resolution request is sent to a hub to acquire a routable IP address. The packets sent to the hub are encapsulated, and encrypting until a resolution reply is received and until security associations (SAs) have been exchanged. Then a VPN is established between the ingress and egress PEs and is used for all subsequent packets.
摘要翻译：提出了一种用于提供加密的多点虚拟专用网（VPN）服务的方法，装置和计算机程序产品。多个分组的第一分组在入口提供商边缘（PE）处接收去往与所述出口PE路由器通信的远程服务器的多个分组。执行对第一分组的目的地前缀的查找，并且确定通过mGRE隧道可以达到第一分组的下一跳。将解析请求发送到集线器以获取可路由的IP地址。发送到集线器的数据包被封装，并进行加密，直到收到解决回复，直到交换安全关联（SA）为止。然后在入口和出口PE之间建立VPN，并用于所有后续数据包。
