20100063988 | Service Insertion in a Computer Network Using Internet Protocol Version 6 Techniques - Apparatus, methods and computer programs enable carrying service insertion architecture data plane packets in IPv4 or IPv6 networks by packaging destination addresses using IPv6 mechanisms. For example, a data processing apparatus is configured for receiving, from a service broker, a service label and an Internet Protocol version 6 (IPv6) address of a first service node; receiving an IPv4 packet requesting a service associated with the first service node; creating an IPv6 packet comprising a service label in a Flow Label field of the IPv6 packet, the IPv6 address of the first service node in a destination address field of the IPv6 packet, and the IPv4 packet in a payload field of the IPv6 packet; forwarding the IPv6 packet to the first service node. Approaches allow service insertion architecture support for all-IPv6 traffic including tunneled and non-tunneled techniques for environments in which user applications place data in the flow label field. | 03-11-2010 |
20100085977 | Optimized Dynamic Multipoint Virtual Private Network Over IPv6 Network - Method and apparatus including registering a first spoke router with a hub router, forwarding an Internet Protocol version Four (IPv4) data packet from the first spoke router to a second spoke router over an Internet Protocol version Six (IPv6) multipoint tunnel via the hub router, transmitting a binding information associated with the first spoke router from the hub router to the second spoke router, and establishing a direct communication path by the second spoke router with the first spoke router based on the received binding information are provided. | 04-08-2010 |

20080317019 | Managing Mobile Nodes In A Lawful Intercept Architecture - In an embodiment, a care-of address associated with a first node coupled to a communications network via an access node is received. The care-of address may be contained in a notification message sent by a home agent associated with the first node or by a binding update message sent by the first agent. The access node is identified using the care-of address. A request to tap communications associated with the first node at the access node is generated and the request is forwarded to the access node to cause communications associated with the first node to be tapped at the access node. | 12-25-2008 |
20090034430 | INFRASTRUCTURE FOR MEDIATION DEVICE TO MEDIATION DEVICE COMMUNICATION - Methods and apparatus for providing a mediation device infrastructure that allows a mobile node to be tapped while roaming among and within service providers are disclosed. In one embodiment, a method includes determining when a node that is tapped by a first mediation device has moved from a first domain associated with the first mediation device into a second domain associated with a second mediation device. A first packet is sent to the second mediation device if the node has moved. The first packet provides an indication that the second mediation device is to tap the node. The method also includes opening a call data channel to the second mediation device, and receiving information from the second mediation device on the call data channel that is obtained by the second mediation device from the node. Finally, the method includes providing the information to the first mediation device. | 02-05-2009 |

20090122985 | DISTRIBUTION OF GROUP CRYPTOGRAPHY MATERIAL IN A MOBILE IP ENVIRONMENT - In one embodiment, a Home Agent receives a Mobile IP registration request from a group member, where the group member is a Mobile Node. The Home Agent generates a mobility binding for the group member that associates the group member with a care-of address, wherein the group member is a member of one or more groups. The Home Agent generates a Mobile IP registration reply, where the Mobile IP registration reply identifies one or more key servers. Each of the one or more key servers serves at least one of the one or more groups and is adapted for distributing group cryptography material to members of each group that is served by the corresponding key server. The Home Agent sends the Mobile IP registration reply to the group member, thereby enabling the group member to obtain cryptography material for at least one of the one or more groups from at least one of the one or more key servers to enable the group member to use the cryptography group material to securely communicate with other group members. | 05-14-2009 |
