Abstract: A live broadcast method includes: receiving, by a live broadcast client, a push-stream address sent by the live broadcast management server; sending, by the live broadcast client, a proxy push-stream request to a live broadcast proxy client; and sending, by the live broadcast client, collected live broadcast data to the live broadcast proxy client, and pushing the live broadcast data to a live broadcast server over an uplink of a dedicated network connected to the live broadcast proxy client.

Abstract: Embodiments of the present disclosure disclose a live broadcast method and system, and a related device. The method in the embodiments of the present disclosure includes: receiving, by a live broadcast client, a push-stream address sent by the live broadcast management server; sending, by the live broadcast client, a proxy push-stream request to a live broadcast proxy client; and sending, by the live broadcast client, collected live broadcast data to the live broadcast proxy client, and pushing the live broadcast data to a live broadcast server over an uplink of a dedicated network connected to the live broadcast proxy client.

Abstract: The invention relates to the field of information technologies, and discloses a terminal, a cache server, and method and apparatus for obtaining a video fragment, so as to reduce a delay of playing a video fragment. The method includes: in response to a trigger condition for obtaining a video fragment, determining that a video fragment needing to be obtained by a terminal is a numbered video fragment of a video file, obtaining video index information of the video file from a cache server, determining a download address of the numbered video fragment according to a download rate of the terminal and the video index information, sending a request message for obtaining a numbered video fragment to the cache server, where the request message for obtaining a video fragment includes the download address of the numbered video fragment and receiving the numbered video fragment returned by the cache server.

Abstract: A method for distributing file data includes: obtaining a first request message of a first client for downloading a first file, and determining an autonomous system (AS) where the first client is located; searching the AS for edge servers that support peer to peer (ES-Ps), and returning the address of at least one ES-P storing the first file to the first client; and sending the first file stored in the ES-P to the first client according to the client information returned by the ES-P. Related devices and systems are also provided. The present invention may speed up the file data distribution, reduce the restriction of the file data distribution due to fixed bandwidth of the ES, and enable P2P data streams to be converged into an AS, thus reducing the impact on backbone networks.

Abstract: A method for constructing a network topology is applied in a streaming delivery system. The streaming delivery system includes: a center server (CS-P), an edge server (ES-P), a request scheduling server (RRS-P), and a client. The disclosed embodiments utilizes the upload capabilities of the client to transmit a part of streaming data, thus consuming fewer center server resources. By constructing the network topology, the disclosed embodiments enable the client to obtain a part of streaming data from other clients, reduces the load capability requirements for the server, and ensures that a streaming delivery network may provide streaming live services with higher bandwidths and better quality.

Abstract: A data distribution method, a data distribution system and relevant devices in an edge network are provided. The method includes: obtaining a data download request from a client, and obtaining a content ID of data under a certain protocol, where the content ID is carried in the download request; and searching for an edge network content ID that corresponds to the content ID and uniquely identifies a data content in an edge network, obtaining corresponding client information by using the edge network content ID as an index, and returning data source information that carries the client information to the client. Therefore, the data is sharable as far as possible throughout the edge network, and the impact on the backbone network is relieved effectively.

Abstract: A media delivery system includes a media manager (MM) a central server that supports peer to peer (P2P) technology (CS-P), a request routing system that supports P2P technology (RRS-P), and an edge server that supports P2P technology (ES-P) and multiple P2P clients. A method for playing streaming media based on the above media delivery system includes: the MM publishes a live channel notification to the CS-P, RRS-P, and ES-P; the CS-P obtains streaming data packets from a live source and parses and slices the packets to generate slice data; the ES-P obtains the slice data from the CS-P and/or other ES-Ps that are able to provide slice data and caches the slice data; and the P2P client obtains the slice data from the ES-P or other P2P clients and delivers the data, or the data is played by a local player after an assembly operation by the P2P client. With the P2P technology, the present invention improves the prior media delivery network and realizes the playing of streaming media to a large number of clients.
