Abstract

The invention discloses an open storage managing and scheduling method and system based on a software-defined network. The system comprises an Openflow interchanger, an SDN network controller, an extra-domain origin server and one or more users. The open storage managing and scheduling system is characterized further comprising one or more intra-domain caching servers which serve as intra-domain origin servers used for storing resources for the users to request in a network, one or more users request the resources through the Openflow interchanger, requests of one or more users are forwarded to the SDN network controller through the Openflow interchanger, the resources requested by the users are cached to the intra-domain caching servers closest to the users, the SDN network controller guides the requests of the users again to the closest intra-domain caching servers which the resources requested by the users are cached in, and the requested resources are acquired from the caching servers according to the requests which are guided again.

Description

technical field [0001] The invention belongs to the technical field of computer communication networks, and in particular relates to a software-defined network-based open storage management and scheduling method and system. Background technique [0002] Information-Centric Networking (ICN) is a new type of network structure centered on information or content, shifting from focusing on addresses and hosts to focusing on information content required by users and applications. The characteristics of the ICN architecture are as follows: 1) Content-centric request-response model; 2) Routing based on content naming; 3) In-network caching; 4) Security mechanism embedded in content. [0003] There are certain shortcomings in the ICN architecture: 1) Lack of active push of content; 2) Lack of centralized control mechanism for the entire network; 3) The coupling of routing node data plane and control plane requires high performance of ICN routing node hardware. [0004] Software Defi...
