Abstract: The embodiments of the present application provide a service state determining method for a service processing device and a scheduling device. In the method, the scheduling device can determine the service state of the service processing device by sending the service request to the service processing device and determining to receive the response message returned by the service processing device for the service request, thus, the scheduling device can allocate the service processing device for this service request according to the service state of the service processing device subsequently, thereby avoiding the problem that the service processing device allocated for the service request by the scheduling device cannot process this service request, ensuring that the service requested by the service request can be normally realized, improving the safety and stability of the network and improving user's experience.

Abstract: The embodiments of the present application provide a file storage method and an electronic device. The file storage method includes: receiving a file to be stored; determining a currently stored folder with a lowest storage priority after the storage space of a disk exceeds a preset threshold; and selecting and deleting a file from the determined folder, and storing the file to be stored in the disk. The embodiments of the present application can improve the utilization value of the storage space of the disk and further improve the performances of the video server; since the files with higher priority are retained, when called, these files do not need to be regenerated or obtained from other servers, thereby improving the utilization rate of system resources and also enhancing the experience of a video requested by the user.

Abstract: Disclosed are a method, a device and a system for obtaining live video. The method for obtaining live video includes: receiving an uploading request for uploading live video from a host user; selecting a resource server for processing the uploading request among multiple distributed resource servers; and sending the uploading request to the resource server so that the resource server receives the live video uploaded by the host user.

Abstract: Disclosed are a method, an electronic device and a system for acquiring video data. The method includes: first of all, receiving, by a content distribution network (CDN) server, an acquisition request of a video source server access path sent by a client; then sending the acquisition request to a scheduling server so that the scheduling server acquires access path information corresponding to the acquisition request; then receiving the access path information sent by the scheduling server; and at last acquiring and sending video data in the video source server to the client according to the access path information.

Abstract: Disclosed are a method and electronic device for data rate adaption in online media services, the method including: collecting and analyzing network bandwidth information of users to obtain bandwidth utilization; determining a corresponding optimal data rate according to the bandwidth utilization; comparing the optimal data rate with a data rate of a current streaming media transmission, and deciding whether to adjust the data rate of the current streaming media transmission; maintaining the data rate of the current streaming media transmission and transmitting stream media data to users if adjustment is not necessary; or transmitting stream media data to users based on the optimal data rate if adjustment is necessary. The stream media business systems can adapt to time-varying characteristics of the channel to achieve coherence and stability of the stream media data transmission to improve application service quality to a certain extent.

Abstract: Disclosed are a method and system for bandwidth allocating based on online media services, the method including: categorizing users into a plurality of categories according to users' attributes, assigning a measurement interval corresponding to each category, and providing a measurement value corresponding to each sub-category of each category according to the measurement interval; counting the measurement value of current accessing user in reference to the plurality of sub-categories of the plurality of categories and determining an overall score of the accessing users; comparing the overall score of the accessing users with a predetermined scoring/bandwidth model, determining an amount of bandwidth allocation of the accessing user and allocating bandwidth to the user. Thus, the disclosure provides techniques to determine online network bandwidth allocation according to different users, and provides users with better service and better quality assurance.

Abstract: Disclosed are a node distribution method and control center, the method comprising: receiving a scheduling request message sent by a UE; according to the scheduling request message, checking whether the UE is in a predetermined set; if yes, then checking whether the bandwidth of the node configured for the UE is occupied, and obtaining the check result, the node being a preferred node preconfigured for the UE; according to the check result, scheduling the UE to access the preferred node or other nodes. The node distributing method and control center provided in the present invention can balance the pressure between nodes, preferentially use resources, improve the quality of service of nodes, and increase website response speed.
