Publication number: 20180295204Abstract: The present technology provides a new content-based centrality metric that may be used for allocating content to caches in a network. The proposed method for measuring centrality and allocating content not only considers the topology of the network, but also the distribution of cache spaces and content among the cache spaces in the network in order to improve how content may be allocated. This approach to content allocation enables improved content retrieval in the form of higher cache hit rates, lower delays and improved network performance.Type: ApplicationFiled: November 24, 2017Publication date: October 11, 2018Applicant: Futurewei Technologies, Inc.Inventor: Cedric Westphal
