Abstract: The present invention provides a live video transmission method and system and an apparatus. According to the method, an M2U device receives a UDP request sent by a client, where the UDP request includes a live channel identifier and is used to request video data of a live channel corresponding to the live channel identifier, and the live channel identifier includes a multicast address or a URL. Then, the M2U device obtains the video data corresponding to the live channel identifier, and obtains a source IP address and a source port of the UDP request, where the source IP address and the source port of the UDP request are used as a destination IP address and a destination port of a UDP unicast packet to be subsequently sent to the client.

Abstract: Embodiments of the present application provide a label switching path calculation method and a label switching path calculation device. In the method, by performing hierarchical level and domain value planning on a node in a network in advance, when an LSP is calculated, hierarchical domain information about each node is acquired, and the LSP is calculated using the acquired hierarchical domain information about each node. Since the hierarchical domain information about each node designates a network position where the node is located, it can be avoided that an LSP obtained by calculation reroutes an access layer according to the hierarchical domain information about each node and a satisfaction criterion for the LSP during the LSP calculation process. In addition, the technical solution provided in the embodiments of the present application needs no manual intervention in the whole LSP calculation process, realizing the automatic calculation of an LSP.
