摘要： The present invention discloses a method for implementing fast multicast and a system thereof. The system comprises multicast protocol, forwarding plane and fast multicast control plane, and the fast multicast control plane further comprises management module and agent module. The method comprises steps of: determining an edge node of time domain overlapping sub-tree of corresponding multicast tree in the multicast service according to the analysis of time domain; initiating the static multicast member of multicast service on said edge node, so that an interface at which the static multicast member is initiated generates a requirement for multicast service; generating the multicast overlapping sub-tree from said edge node to a multicast root node, so that the multicast service flow is transmitted to said edge node in advance; after sending out the requirement for the multicast service flow through any receiver at said edge node, multicast tree path establishes a multicast forwarding tree from the receiver to the edge node, the multicast service flow will be transmitted from this edge node to the receiver. The present invention can effectively reduce the delay of multicast application.

摘要： A method for linearizing a radiation detector is provided, the method including measuring a pulse height spectrum of a predetermined radiation source, identifying at least one spectrum template for the predetermined radiation source, and determining a linearization function by comparing the measured pulse height spectrum with the at least one identified spectrum template. The at least one spectrum template is a predefined synthesized energy spectrum for the predetermined radiation source and for the corresponding radiation detector.
