| 20080267189 | METHOD AND SYSTEM FOR VERIFYING UPDATE INFORMATION IN BGP - A method for verifying update information in Border Gateway Protocol (BGP), includes: upon receipt of an update message, verifying, by an Autonomous System (AS), the update message according to a determined maximum time of verifications; and trusting the update message if the verifications are successful. The update message may be AS_PATH and/or prefix. In the invention, upon receipt of an update message, the AS verifies the update information according to the maximum time of verifications, which ensures that the time of verifications will not exceed the maximum time of verifications when the AS verifies the update information. Accordingly, load on CPU is decreased during verification of the update information and hence the network convergence speed is improved. | 10-30-2008 |
| 20080273509 | Method, System And Device For Optimizing Routing In Mobile IPv6 - This disclosure relates to a method, system and device for optimizing routing in a mobile IPv6. The core is that the communication between a mobile node and a correspondence node is performed in a routing optimization mode, while providing a secure verification, so that the care-of address of the mobile node would not be obtained by a distrustful third party or a distrustful correspondence node. Moreover, to further ensure the privacy of the location of the mobile node, the current care-of address of the mobile node is shielded from the correspondence node by separating the binding cache from the correspondence node. | 11-06-2008 |
