摘要： A method and corresponding device for determining forwarding rule for data packet in Virtual Private LAN Service with Provider Backbone Bridge (PBB-VPLS) network are disclosed. In the method, a value in a backbone service instance identifier (I-SID) field of the received data packet is firstly examined, then a virtual split horizon group corresponding to the data packets is determined based on the I-SID value, wherein the virtual split horizon group defines a forwarding rule for the data packets between different pseudo wire ports of the PBB-VPLS network. With the dynamic split horizon group, the method dynamically adapts to different forwarding rules for multiple I-VPLS instances with different tree topologies, and is capable of supporting multiple I-VPLS instances with different root sites and tree topologies in one B-VPLS instance, thereby ensuring the stability of the backbone network and reducing the network operation cost.

摘要： Apparatus and method for detecting the presence or amount or rate of binding of an analyte in a sample solution is disclosed. The apparatus includes an optical assembly having first and second reflecting surfaces separated by a distance “d” greater than 50 nm, where the first surface is formed by a layer of analyte-binding molecules, and a light source for directing a beam of light onto said first and second reflecting surface. A detector in the apparatus operates to detect a change in the thickness of the first reflecting layer resulting from binding of analyte to the analyte-binding molecules, when the assembly is placed in the solution of analyte, by detecting a shift in phase of light waves reflected from the first and second surfaces.
