摘要： Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded to one of the Mobile Nodes assigned that Home Address.

摘要： Methods and apparatus for optimizing IP multicast data transmission in a mobile IP environment include a Foreign Agent that is capable of receiving an information request associated with a host membership report sent from a mobile node and for providing information identifying a Home Agent associated with the mobile node to a multicast router process to enable the multicast router process to send a join host group message to the Home Agent. A Home Agent receives the join host group message and sends the join host group message toward a source of IP multicast data packets. Both the Foreign Agent and the Home Agent set up a data path between the Home Agent and the Foreign Agent, thereby enabling data packets addressed to the multicast group address to be forwarded by the Home Agent to the Foreign Agent. The Home Agent does not replicate multicast IP data packets addressed to the multicast group address prior to being forwarded by the Home Agent to the Foreign Agent. Rather, the multicast router process is responsible for replication and transmission of multicast IP data packets to one or more network segments associated with the Foreign Agent.
摘要翻译：用于在移动IP环境中优化IP多播数据传输的方法和装置包括能够接收与从移动节点发送的主机成员资格相关联的信息请求并且用于提供标识与移动节点相关联的归属代理的信息的外部代理到组播路由器进程以使得组播路由器进程向归属代理发送连接主机组消息。归属代理接收加入主机组消息，并将连接主机组消息发送到IP组播数据包的源。外部代理和归属代理都在归属代理和外部代理之间建立数据路径，从而使寻址到多播组地址的数据包由归属代理转发给外地代理。在由归属代理转发给外部代理之前，归属代理不复制寻址到多播组地址的多播IP数据包。相反，组播路由器进程负责复制和传输组播IP数据包到与外地代理相关的一个或多个网段。

摘要： Disclosed is a method and apparatus for automatically backing up a Home Agent in Mobile IP. The method employs important components of the widely-used Hot Standby Router Protocol, but extends it to include synchronization of the mobility binding table between an active Home Agent and a standby Home Agent that backs it up. Also disclosed is a more general protocol for extending HSRP and related redundancy protocols to synchronize higher level functions other than mobility binding lists in Mobile IP (e.g., address translation tables in Network Address Translation (NAT), address bindings in Dynamic Host Configuration Protocol (DHCP) servers, dynamic ACL in Reflexive Access List, and TCP and GTP layer context in GPRS support nodes: SGSN & GGSN). Still other protocols that could benefit from HSRP include Lock and Key, Context-Based Access List, IP Security (IPSec), and H.323 gatekeeper.

摘要： Various security mechanisms may be used independently, or in combination with one another, to authenticate the identity of a node during the Mobile IP registration process. First, an Access Point receiving a packet from a node verifies that the source MAC address identified in the packet is in the Access Point's client association table. In addition, as a second mechanism, the Access Point ensures that a one-to-one mapping exists for the source MAC address and source IP address identified in the packet in a mapping table maintained by the Access Point. As a third mechanism, a binding is not modified in the mobility binding table maintained by the Home Agent unless there is a one-to-one mapping in the mobility binding table between the source MAC address and the source IP address. Similarly, the Foreign Agent may also maintain a mapping between the source IP address and the source MAC address in its visitor table to ensure a one-to-one mapping between a source IP address and the associated MAC address.
摘要翻译：各种安全机制可以独立地或彼此组合地使用来在移动IP注册过程期间认证节点的身份。首先，从节点接收分组的接入点验证分组中标识的源MAC地址在接入点的客户端关联表中。另外，作为第二种机制，接入点确保了由接入点维护的映射表中的源MAC地址和源IP地址中的一个一对一映射。作为第三种机制，在归属代理维护的移动性绑定表中，绑定不会被修改，除非在源MAC地址和源IP地址之间的迁移绑定表中存在一对一的映射。类似地，外地代理还可以在其访问者表中保持源IP地址和源MAC地址之间的映射，以确保源IP地址和相关MAC地址之间的一对一映射。

摘要： Methods and apparatus for supporting broadcast traffic in Mobile IP are disclosed. When a Mobile Node registers via a Foreign Agent supporting Mobile IP, the Foreign Agent receives a registration request from a Mobile Node and sends the registration request to a Home Agent. A registration reply received from the Home Agent has a network mask extension including a network mask associated with the home address of the Mobile Node. The Foreign Agent then sends the registration reply to the Mobile Node. Alternatively, the Mobile Node may register via a collocated care-of address, in which case the registration reply is received directly from the Home Agent. Once the Mobile Node has obtained its network mask, it may send packets such as broadcast packets, as well as roam to its Home Agent. Additionally, in accordance with various embodiments, the Foreign Agent duplicates broadcast packets for transmission to Mobile Nodes, rather than receiving the duplicated packets from the Home Agent. In this manner, broadcast traffic in a Mobile IP environment is optimized.
摘要翻译：公开了支持移动IP广播流量的方法和装置。当移动节点通过支持移动IP的外部代理注册时，外部代理从移动节点接收注册请求，并将注册请求发送到归属代理。从归属代理接收到的注册答复具有包括与移动节点的归属地址相关联的网络掩码的网络掩码扩展。然后，外部代理将注册答复发送到移动节点。或者，移动节点可以通过并置的转交地址进行注册，在这种情况下，直接从归属代理接收注册回复。一旦移动节点获得了网络掩码，它可能会发送数据包，如广播数据包，以及漫游到其归属代理。此外，根据各种实施例，外部代理复制用于传输到移动节点的广播分组，而不是从归属代理接收重复分组。以这种方式，移动IP环境中的广播流量被优化。

摘要： An example method is provided and includes receiving a packet associated with a flow, determining a tunnel identifier for the flow, and determining a flow identifier for the flow. The method includes associating the flow identifier and the tunnel identifier to an Internet protocol (IP) address to generate a binding to be used for a network address and port translation (NAPT). In other embodiments, a routing decision is executed based on the binding between the identifiers and the IP address. The flow identifier can be a context identifier (CID), and the tunnel identifier can be a softwire tunnel ID. In yet other embodiments, the packet can be tagged as part of an encapsulation operation, which includes providing information about a network location at which the network address and port translation is to be executed.
