    摘要： In one implementation, a method for managing access to mobile endpoints leverages the always-on nature of a first internet layer protocol to expand the reach of a second internet layer protocol. A network device receives a request originating from a remote host. The request includes a domain name of a mobile endpoint. The network device queries a database using the domain name for a first address of the mobile endpoint as designated according to the first internet layer protocol. The network device transmits a wake up message to the mobile endpoint using the first address. A data bearer for communication with the second internet layer protocol is established based on the wake up message, and a second address is assigned to the mobile endpoint. The second address is forwarded to the remote host, allowing communication between the remote host and the mobile endpoint.

    摘要： A system may provide connectivity service in a multi-tenant network. A first node in the multi-tenant network can receive data packets, each of the data packets identifying one of a plurality of tenant devices. The first node can determine an Internet Protocol (IP) address associated with each of the data packets. The first node can determine a Virtual Local Area Network Identifier (VLAN ID) based on the IP address, the VLAN ID being a unique identifier of a respective one of the tenants. The first node can add the VLAN ID of a corresponding one of the tenants into a header of each of the data packets. The first node can transport the data packets to a second node in the multi-tenant network via a multi-tenant network tunnel protocol.

    摘要： According to one embodiment, an anchor access gateway receives packets from a home agent. The packets are destined for an access terminal, and the anchor access gateway serves the access terminal. The packets are forwarded to the access terminal. The anchor access gateway receives a handoff request from a target access gateway. The handoff request requests a handover from the anchor access gateway to the target access gateway. The packets are forwarded to the target access gateway in accordance with the handoff request.

    摘要： Synchronizing mobility messaging includes receiving an Internet Protocol (IP) address at a Dynamic Host Configuration Protocol (DHCP) server. The IP address is sent by a home agent of a mobile client, where the home agent has a mobility binding for the mobile client. A DHCP request requesting an IP address for the mobile client is received from the mobile client. The DHCP server assigns the IP address to the mobile client. A DHCP acknowledgement comprising the assigned IP address is sent to the mobile client.

    摘要： According to one embodiment, providing network redundancy includes configuring a session registrant database to have one or more virtual standby states. Each virtual standby state corresponds to an active router. The session registrant database receives session information from the active router(s) and determines that an active router has failed. A virtual standby state corresponding to the failed router is set to a virtual active state. A second router is configured to have a standby state associated with the set virtual active state. The session information received from the failed router is transferred to the second router, and the second router is configured to have an active state.

    摘要： A system for efficiently reauthenticating a client of a network. In a specific embodiment, the system includes an authentication server and a Security GateWay (SGW) in communication with the client. The SGW includes reauthentication information associated with the client. In a more specific embodiment, the authentication server includes an Authentication, Authorization, and Accounting (AAA) server. The SGW further includes one or more routines for employing the reauthentication information to reauthenticate the client. The AAA server performs initial authentication of the client to enable client access to the network, which yields the reauthentication information. The reauthentication information includes one or more keys and/or counters, such as an authorization key, an encryption key, and a master key, which is/are predetermined by the AAA server.

    摘要： An apparatus for providing mobility in an Internet protocol (IP) network environment is provided that includes a cell site element operable to receive an address resolution protocol (ARP) signal from a base station. The ARP signal is associated with a selected mobile station that can roam between networks. In response to the signal, the cell site element evaluates a table that identifies a plurality of mobile stations and if the selected mobile station is not present in the table, then a mobility registration request is generated and communicated to a next destination.
