Problems solved by technology

Traditional methods for solving NP-complete problems try to somehow limit the problem to an exhaustive search for a definite solution
These procedures are often computationally expensive, yet still produce undesirable results

[0057] 1 System Overview

[0058] In distributed systems, there are content repositories characterized by a wide range of attributes (e.g., data type, length, popularity, and access patterns) and operational goals (e.g., performance, integrity, and resilience), such that Each content can involve the use of system resources at different levels. For example, more popular content usually requires more access resources (e.g., read bandwidth) to improve its streaming performance; on the other hand, more important content may require more storage space ( For example, for storing redundant data) to ensure data integrity.

[0059] Managing a limited amount of system resources in a manner that best serves the operational goals of content usage can be a complex problem. Also, as the system increases in size, the degree of difficulty will gradually increase. In some systems, it is advantageous to apply domain-specific knowledge in managing system resources involving multiple dimensi...

Abstract

A computer- implemented method includes receiving a description of a pattern of access to a first group of items of content; and partitioning a storage space based at least in part on the description of the pattern of access. The description of the pattern of access is a function of at least a first attribute that characterizes one or more operational objectives of a second group of items of content to be stored in a storage system. The partitioning of the storage space includes defining each one of a plurality of categories in relation to a range of values of the first attribute; and associating each one of the plurality of categories with a respective one of a plurality of resource allocation arrangements.

Description

technical field [0001] This specification is concerned with resource allocation in distributed systems for data storage and access. Background technique [0002] Distributed network-based data storage, for example accessible via the Internet, has various applications. One application is video storage and access. [0003] Over the past decade, online video streaming has grown in popularity among Internet users as residents have immediate and easy access to high-speed Internet services. For example, traditional video delivery systems (e.g., cable TV systems) may no longer meet customers' growing demands for easy access and immediate delivery, and movie customers may soon turn to online video storage that can provide this service. [0004] However, there are many challenges in providing reliable download services to large-scale customers at an affordable cost. For example, building a network-based video storage and transmission system may encounter a dynamically distributed ...
