Abstract: Ultra-lightweight aerogels and methods for fabricating such aerogels from ammonia borane and a support structure, where the support structure is either two-dimensional nanostructures, or hydrocarbon polymer colloids. The components are mixed, then annealed. The properties of the disclosed aerogels can be tuned by controlling the ratio between the support structure and the ammonia borane, or by infiltrating the aerogels with additives.

Abstract: Embodiments of the present invention disclose a method, a duplication point device, a server, and a system for data flow reuse transmission. The method includes: receiving, by a duplication point device, a first data flow request message sent by a first user within a preset time period, receiving a second data flow request message sent by a second user within the preset time period and after receiving the first data flow request message, requesting the first data flow from a server after the current time reaches the end time, receiving the first data flow from the server, duplicating the first data flow, which results in two identical first data flows, and sending one to the first user and the other to the second user respectively.

Abstract: The present invention provides a method for transporting a service flow securely in an Internet Protocol (IP) network, which includes the following steps: a service server sends a first request to a resource manager, requesting to build a service flow path between a calling user and a called user in a logical bearing network; the resource manager chooses a service flow path between a first Provider Edge Router (PE) that the calling user belongs to and a second PE that the called user belongs to in the logical bearing network; the resource manage sends a configuration request message to the first and second PEs; the first and second PEs build flow classification table items including the service flow path according to the configuration request message, respectively, and forward only the service flow matching one of the flow classification table items to corresponding service flow path in the logical bearing network.

Abstract: 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.

Abstract: 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.

Abstract: A method and system for providing QoS service includes analyzing signaling packets by which various soft terminals/hardware terminals register to a system and call the system, extracting the user signaling feature codes, such as the telephone number or domain name of the user and the audio, video and data information, from the signaling packet, and analyzing whether the system has been configured with the QoS information corresponding the signaling feature codes. If the matched configuration information of the user is found, the method and system perform bandwidth limitation and bandwidth guarantee according to the QoS information. In this way, the bandwidths of users do not interfere with each other, and the call quality of users are guaranteed.
