Methods and systems are provided for secure Mobile-IP traffic traversing network address translation (NAT). A virtual-private-network (VPN) tunnel extending between the mobile node and the home agent is established, wherein the home agent comprises a VPN function. Establishing the VPN tunnel comprises (i) the mobile node communicating with the home agent at a public address of the home agent via a private network, a NAT device, and a public network and (ii) the home agent assigning the mobile node a first public address. The mobile node is registered with the home agent. Registering the mobile node comprises (i) the mobile node communicating via the VPN tunnel with the home agent at the public address of the home agent and (ii) establishing the first public address as a home address for the mobile node for, for example, purposes of Mobile-IP communication.

Methods and systems for secure mobile-IP traffic traversing network address translation

Computer-readable media for dynamic quality of service assignment are described. In embodiments, a data packet is received that is part of a communications stream and a dynamically modifiable quality of service indicator (DMQOSI) is embedded into the data packet wherein, in various embodiments, the DMQOSI indicates a prescribed quality of service that is associated with the data packet and is modifiable prior to completing a communication of the communications stream. In various embodiments, the data packet is communicated from a source to a destination that at least periodically references the DMQOSI to ensure that the data packet is being communicated consistent with the prescribed quality of service associated with the data packet.

Dynamic quality of service (QOS) assignment

A method and system are provided to select address providers that provide mobile internet protocol devices with addresses for communication. An embodiment of the method includes obtaining an address request having a dynamic indicator. Upon obtaining an address request with a dynamic indicator, associating the dynamic indicator with one or more address providers based on the dynamic indicator. The address request is then communicated to one of the address providers associated with the dynamic indicator.

Selecting an address provider using a dynamic indicator

Computer-readable media, systems, and methods for dynamic overflow pool allocation are described. In embodiments, a new session registration request is monitored for and, upon receiving the new session registration request, it is determined whether an existing pool associated with a home agent has crossed below a minimal threshold. In various embodiments, if it is determined that the existing pool has crossed below a minimal threshold, an overflow is obtained. In various other embodiments, it is determined whether an existing home agent pool has crossed a maximum threshold and, if so, it is determined whether at least one session remains using the overflow pool. In various other embodiments, if no sessions remain using the overflow pool, the overflow pool is returned.

Dynamic overflow pool allocation

Dynamically modifiable quality of service indicator

A method and system are provided to select address providers that provide mobile internet protocol devices with addresses for communication. An embodiment of the method includes obtaining an address request having a dynamic indicator and a failover counter. Upon obtaining an address request with the dynamic indicator and the failover counter, associating the failover counter with one or more address providers based on the failover counter. The address request is then communicated to one of the address providers associated with the failover provider.
