A method for realizing content connectivity in data center network

Abstract

The invention relates to a realization method for content connection in a data center network. The method comprises the steps of determining users corresponding to request contents; obtaining data centers capable of responding to the request contents; selecting one data center capable of responding to the request contents in a descending mode, according to sizes of idle storage spaces of the data centers capable of responding to the request contents, adding the selected data center to a k-content connection data center set, wherein the k is a positive integer; carrying out k-content connection judgment on the k-content connection data center set; obtaining k non-intersected paths according to the k-content connection data center set and carrying out path redirection on the k-content connection data center set; and carrying out content deployment on the k-content connection data center set. According to the method provided by the invention, the data center is reasonably selected for content deployment according to the k non-intersected paths from point to point and the request contents of the user, and the connection from the users to the contents is ensured under the multi-fault condition.

Description

technical field [0001] The invention relates to the field of power communication, in particular to a method for realizing content communication in a data center network. Background technique [0002] With the development and massive deployment of emerging services such as cloud computing and big data, data centers and data center networking have developed rapidly. Large-scale enterprises at home and abroad have established data centers covering different business capabilities according to their respective industry characteristics and business types. From 2011 to the first half of 2013, a total of 255 data centers were planned and constructed across the country, and 173 have been put into use, with a total land area of ​​about 7.132 million square meters and a total area of ​​computer rooms of about 4 million square meters. Among them, there are 23 ultra-large data centers (with a scale of more than 10,000 standard racks, and a standard rack with a power of 2.5 kilowatts), a...

Problems solved by technology

In a data center network that supports content connectivity, content can be replicated in multiple storage locations, so that users can optimally select the requested storage location to obtain content; content connectivity effectively improves the data center network’s response to Survivability in case of multiple failures and natural disasters; in the existing technology, under the condition of ensuring the connection of given content, it is impossible to reasonably select the data center to store the content, which wastes a lot of storage resources
