Abstract: The method of the present disclosure includes: after a graph partitioning apparatus extracts an edge, first determining whether an aggregation degree between a currently extracted edge and an allocated edge in a first device satisfies a preset condition; then, when the preset condition is satisfied, determining whether a quantity of allocated edges stored in the first device is less than a first preset threshold; and allocating the currently extracted edge to the first device when the quantity is less than the first preset threshold. In this way, an aggregation degree between allocated edges in each device is relatively high and each device has relatively balanced load. When an edge changes and an edge associated with the particular edge needs to be synchronized, a relatively small quantity of devices need to perform synchronization and update, so that costs of communication between devices are reduced, and distributed graph computing efficiency is improved.

Abstract: The present invention provides a method, a device, and a system for delivering live content. A pre-delivery request with respect to live content is sent to a CDN cache device, and the CDN cache device caches the live content according to the pre-delivery request with respect to the live content before a user views the live content, thereby solving the problems of a long delay and poor user experience in playing live content that is not cached because a part of live content cannot be cached in the prior art, ensuring the play quality of all live content, and improving user experience.
