  • Patent number: 9191312
    Abstract: A method and system for implementing a pseudo wire control word capability negotiation are disclosed in the present document. The method includes: when modifying a local control word value, a Provider Edge (PE) acquiring a control word value configured or negotiated locally by an opposite terminal provider edge by sending label request message and receiving label mapping message, and according to the local control word value and the acquired control word value, the provider edge determining a control word value negotiated with respect to a pseudo wire. In the present document, the problem of inconsistency between the control word configurations and the expected negotiation results existing in certain specific scenarios is solved, which enhances the negotiation performance. The technical scheme of the present document makes slight modifications on the existing protocol, and it is applicable to a single segment pseudo wire scenario and a multiple segment pseudo wire scenario.

  • Publication number: 20140358725
    Abstract: In some embodiments, an app provides a geolocation-limited marketplace limited to a pre-defined period of time. The geolocation-limited marketplace is accessible only by the users in a predefined geographical area. Typically, the predefined geographical area is limited to an area small enough for a user to walk from one end to the other in a short period of time. The pre-defined period of time is of some limited length of time that may occur at a pre-defined interval. In some instances, the period of time is one hour.

  • Patent number: 8730979
    Abstract: The present invention provides a method and system for increasing forwarding efficiency of a virtual private LAN services network. The method includes: a root node provider edge (PE) in the VPLS network transmitting at least one of broadcast message, multicast message and unknown unicast message to leaf nodes PE in the same VPLS through a point-to-multipoint pseudo wire (P2MP PW). The present invention transmits messages through the P2MP PW between a PE and other PEs, thus decreasing the number of redundant messages on a physical link, increasing the forwarding efficiency of network, and reducing the network operating costs.

  • Publication number: 20130131483
    Abstract: A heart rate alarm system includes an article of clothing, at least two conductive units, at least one alarm device, a heart rate measurement unit, a first transmission unit, a second transmission unit, and an operation unit. The at least two conductive units are coupled to each other through at least one conductive fibric. The heart rate measurement unit measures a heart rate through the at least two conductive units, and generates a control signal and a heart rate value according to the heart rate. The first transmission unit transmits the control signal to the at least one alarm device and transmits the heart rate value. The at least one alarm device generates at least one alarm signal according to the control signal. The operation unit calculates a heart beat period, a heart physiological age, indicators of autonomic nervous system, and/or a calorie consumption indicator.

  • Publication number: 20110284466
    Abstract: A durable on-column tunneled frit was developed for use in nanoflow UPLC systems. The frit was tunneled during sol-gel reaction. The tunneled-frit fabrication process is easy and reproducible in terms of back pressure and durability. This design creates low backpressure with high liquid flow, which is suitable for the nanoflowUPLC application. A short packing (2 cm C18 particle) tunneled-frit column was demonstrated to sustain 10,000 psi continuous liquid flow for over one week without any particle leakage or pressure instability. The tunneled-frit was also successfully applied to the fabrication of nanoUPLC trapping and analytical column system. It was demonstrated to have high separation efficiency and sensitivity for the analysis of tryptic peptides as well as improved detection sensitivity for phosphopeptide analysis.
