  • Publication number: 20100316054
    Abstract: A method, system, and apparatus for sending mapping information are disclosed. The method includes the following steps: An endpoint searches a mapping server to obtain Egress Tunnel Router (ETR) information used for forwarding a data packet sent by the endpoint in a transit network; and the endpoint adds the ETR information to the data packet and sends the data packet to an Ingress Tunnel Router (ITR). With the present invention, the ITR does not need to search for Routing Locator (RLOC) information or Autonomous System Number (AS No.) information, the pressure of searching for mapping information on the ITR is relieved, the problems such as forwarding performance deterioration and packet loss caused by ITR overload are avoided, and the risks of Distributed Denial of Service (DDOS) attacks are reduced.

  • Publication number: 20100241193
    Abstract: A cochlear implant provides electrical pulses to neurons and is configured to convert the excitation signal into a sparsified signal for electrically stimulating the neurons, thereby reducing the redundancy of the stimuli applied to the neurons. A signal analyser is configured to perform dimension reduction or factorisation of said excitation signal in the time domain or in the frequency domain followed by a sparse transform, the resulting relatively clean output signal providing the input to an inverse transformation step to create the sparsified signal. The dimension reduction or factorisation can be performed by principal component analysis (PCA), and the sparse transform can be performed by independent component analysis (ICA).

  • Publication number: 20040177107
    Abstract: The invention discloses a method for providing services with guaranteed Quality of Service (QoS) in an IP access network. In this method, when the network control layer applies for network resources to the access network as response to the service request of needing guaranteed QoS, the edge router determines whether the access network can provide enough resources for the service. If there are enough resources, the edge router sends QoS parameters to the access network end devices which make QoS control to get a guaranteed QoS.
