Abstract: A network, a method and devices (i.e., mobile node, access router, home agent, destination home agent) are described herein for enabling an efficient hybrid route optimization between two mobile endpoints so they can re-direct their data traffic to an optimal path without exchanging any mobility signaling messages.

Abstract: A method and a Mobile Node (110) are provided for authenticating an Advertisement message received from an Access Router (150,160) through an Access Point (120,130,140) . The Advertisement message comprises a Hashed Nonce Value and a Nonce Index corresponding to a Nonce Value held in the Access Router. Upon receiving the Advertisement message from the Access Point, the Mobile Node initiates a process for configuring an IP address, by use of information received in the Advertisement, for having a session with the Access Point and the Access Router. In parallel, either the Access Point or the Mobile Node sends the Nonce Index directly to the Access Router. The Access Router replies with the Nonce Value sent to the Mobile Node. The Mobile Node hashes the Nonce Value received from the Access Router and compares a Result of the hashing with the Hashed Nonce Value. If the Result matches the Hashed Nonce Value, the Advertisement is considered authenticated and the IP address configured according to the Advertisement is kept in the Mobile Node.

Abstract: A method for maintaining connectivity between a mobile node and a corresponding node when the mobile node connects to a foreign network, where the foreign network and the home network are Internet protocol version 6 (IPv6) networks but the corresponding node is an Internet protocol version 4 (IPv4) node. The method includes receiving at the home agent node an IPv6 care-of address, determining that the IPv6 care-of address belongs to the foreign network and that the foreign NAT64 node has a prefix to generate virtual IPv6 addresses and sending a prefix binding request message to a home NAT64 node to bind the prefix to the home address of the mobile node for translation between IPv6 and IPv4.

Abstract: A method performed by a network element for providing micro-mobility in a network to a mobile node including the steps of receiving a registration request message at the mobility anchor point from an access router that is currently coupled to the mobile node, wherein the registration request message includes an endpoint identifier of the mobile node and a local care-of address of the mobile node, establishing a label switch path (LSP) between the mobility anchor point and the access router, storing the endpoint identifier in a binding entry along with the local care-of address, a regional care-of address, the label switch path and an egress interface, advertising the endpoint identifier with associated regional or local care-of address of the mobile node, and forwarding data packets, received at the mobility anchor point from a corresponding node that have the regional or local care-of address, to the mobile node using the LSP.

Abstract: Un procedimiento para un encaminador de acceso para proteger una red de telecomunicaciones contra un ataque por inundación procedente de un nodo de red de múltiples interfaces, proporcionando el encaminador de acceso comunicaciones entre el nodo de red de múltiples interfaces y un nodo de red que actúa como nodo correspondiente NC para el nodo de red de múltiples interfaces, comprendiendo el procedimiento las etapas de: transferir (300) datos entre el nodo de red de múltiples interfaces y el NC; determinar (302) si el nodo de red de múltiples interfaces sigue siendo asequible; si el nodo de red de múltiples interfaces sigue siendo asequible, continuar transfiriendo datos entre el NC y el nodo de red de múltiples interfaces; y después de determinar que el nodo de red de múltiples interfaces ya no es asequible, dar al NC instrucciones para que limpie la información almacenada en memoria intermedia asociada con el nodo de red de múltiples interfaces.

Abstract: A method and Mobility Anchor Point (MAP) are provided for authenticating an update message received at the MAP from a Mobile Node (MN). A table entry is created in the MAP, following receipt of a first message comprising a public key of the MN, a first pointer and a first comparison data, information elements received from the first message being stored in the table entry. The MAP then receives an update message requesting binding of a Local Care-of Address (LCoA) with a Regional Care-of Address (RCoA). The update message further comprises a second pointer and a second comparison data. The MAP locates the table entry by use of the second pointer. The MAP then authenticates the second message by hashing one of the first or second comparison data and comparing a result of the hashing with the other one of the first and second comparison data. If a match is found, the second message is authenticated and the MAP binds the LCoA and the RCoA by storing both addresses in the table entry.

Abstract: A method and apparatus for establishing a cryptographic relationship between a first node (102) and a second node (101) in a communications network. The first node receives at least part of a cryptographic attribute of the second node, uses the received at least part of the cryptographic attribute to generate an identifier for the first node. The cryptographic attribute may a public key belonging to the second node, and the identifier may be a Cryptographically Generated IP address. The cryptographic relationship allows the second node to establish with a third node that is entitled to act on behalf of the first node.
