摘要： Methods and apparatus for enabling mobility of a node that does not support Mobile IP are disclosed. When an AP receives a data packet, the AP may compare the data packet (e.g., source address) with the AP information for one or more APs to determine whether to send a registration request on behalf of the node. More particularly, the AP determines from the source address whether the node is located on a subnet identical to a subnet of the AP. If the node is located on the subnet of the AP, no Mobile IP service is required on behalf of the node. However, when it is determined from the source address that the node is not located on the subnet identical to the subnet of the Access Point, the AP composes and sends a mobile IP registration request on behalf of the node. For instance, the mobile IP registration request may be composed using the gateway associated with the “home” AP (e.g., having a matching subnet) as the node's Home Agent.
摘要翻译：公开了一种能够实现不支持移动IP的节点移动性的方法和装置。当AP接收到数据分组时，AP可以将数据分组（例如，源地址）与一个或多个AP的AP信息进行比较，以确定是否代表节点发送注册请求。更具体地，AP从源地址确定节点是否位于与AP的子网相同的子网上。如果节点位于AP的子网上，则代表节点不需要移动IP服务。但是，当从源地址确定节点不在与接入点的子网相同的子网上时，AP代表该节点组合并发送移动IP注册请求。例如，可以使用与家庭AP相关联的网关（例如，具有匹配的子网）作为节点的归属代理来组合移动IP注册请求。

摘要： In accordance with various embodiments, a Home Agent receives a registration request and sends a registration reply having a network mask extension including a network mask associated with the home address of the Mobile Node. 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, when a Home Agent receives a broadcast packet, it forwards the broadcast packet to a care-of address of the broadcast packet without duplicating the broadcast packet. Instead, the Foreign Agent obtains the subnet from the broadcast packet, identifies the Mobile Node(s) on that subnet, and duplicates the broadcast packet for transmission to the identified Mobile Node(s).
摘要翻译：根据各种实施例，归属代理接收注册请求并发送具有网络掩码扩展的注册答复，该网络掩码扩展包括与移动节点的归属地址相关联的网络掩码。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，当归属代理接收到广播分组时，它将广播分组转发到广播分组的转交地址而不复制广播分组。相反，外部代理从广播分组获取子网，识别该子网上的移动节点，并复制广播分组以传输到所识别的移动节点。

摘要： Methods and apparatuses for conserving addresses. The invention allows a mobile node to manage its own address, shifting responsibility away from the home agent. The home agent is able to detect when a mobile node has already been assigned an address for use of resources on the network. When the home agent recognizes that the mobile address has already been assigned an address, it allows the mobile node to use its already-assigned address in connection with mobile IP services. Additionally, the mobile node can be notified that it is now responsible for renewing the address.

摘要： The present disclosure generally provides techniques for establishing a unique, ephemeral home address (hoa)/home agent address (ha′) address pair that may be limited to use in a session having a defined lifetime. Limiting the use of this dynamic address pair to a session lifetime and by preventing a mobile node from knowing the static address of a home agent may help protect the home agent from attacks.

摘要： Methods and apparatus for optimizing NAT traversal in Mobile IP are disclosed. Various mechanisms may performed independently or in combination with one another. A first mechanism enables one-way keep alive messaging to the Home Agent, while a second mechanism enables two-way keep alive messaging to the Home Agent, thereby enabling an entry in a NAT translation table to be maintained. The two-way keep alive messaging requires that the Home Agent send an acknowledgement message, while the one-way keep alive messaging does not. Keep alive messaging may be performed at the Mobile Node or the Foreign Agent. A third mechanism enables a Foreign Agent to encapsulate a registration request packet with the Foreign Agent care-of address in the source IP address field rather than an egress interface of the Foreign Agent. A fourth mechanism enables a Mobile Node to force a Home Agent to perform UDP tunneling.
摘要翻译：公开了用于优化移动IP中NAT穿越的方法和装置。各种机制可以独立地或彼此组合地执行。第一种机制使得能够向归属代理单向保持活动消息传递，而第二种机制允许向归属代理双向保持活动消息传递，从而使NAT转换表中的条目得以维护。双向保持活着消息传递要求家庭代理发送确认消息，而单向保持活动消息传递不需要。可以在移动节点或外部代理处执行活动消息传递。第三种机制使外部代理能够在源IP地址字段而不是外部代理的出口接口封装具有外部代理转交地址的注册请求分组。第四种机制使移动节点能够强制归属代理执行UDP隧道。

摘要： In accordance with one aspect of the invention, methods and apparatus for distributing a Mobile IP registration request to one of a plurality of Home Agents are disclosed. A registration request is received from a Foreign Agent to which the Mobile Node has roamed. One of the plurality of Home Agents is selected. The registration request is then forwarded to the selected one of the plurality of Home Agents. The source IP address of the registration request is an IP address of the Foreign Agent to which the Mobile Node has roamed, thereby enabling the selected one of the plurality of Home Agents to send a Mobile IP registration reply directly to the Foreign Agent without interception by the network device.
