Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] The present invention proposes a caching strategy for a content-centric network based on software-defined networking, and utilizes the advantages of logical centralization and perception of the entire network under the converged architecture of software-defined networking and content-centric network. According to the global network topology and content information, and perform centralized and overall cache optimization on the content; this method uses the importance and edge of nodes and the popularity of content to carry out overall cache optimization mathematical modeling, and applies particle swarm intelligence algorithm in the optimization process to speed up The speed at which the cache optimization converges. The cache decision algorithm proposed by the invention can obviously improve the cache hit rate and reduce the path extension rate....

Abstract

The present invention proposes a software-defined network-based content-centric network caching method. Under the fusion architecture of software-defined network and content-centric network, through the controller's perception of global network topology and cache information, centralized control and monitoring of cache nodes and content Overall cache optimization. The controller periodically collects statistics on the cache information, and then performs cache optimization according to the cache decision request of the data layer. The invention incorporates the importance degree and edge degree of the node and the popularity degree of the content into the cache decision-making strategy, carries out mathematical modeling according to the above information, and optimizes the mathematical model by using the particle swarm intelligent algorithm. The invention makes full use of the controller's advantages of global control and logic centralization, so that the cache can perform decision-making optimization under multi-node cooperation.

Description

technical field [0001] The invention belongs to the caching decision-making strategy under the fusion architecture of software-defined network and content-centric network, and relates to the programmability of the controller for data layer operation, and the caching of content by the controller according to the information sensed by the whole network and applying the particle swarm intelligent algorithm decision making. Background technique [0002] In the face of massive Internet traffic dominated by real-time audio and high-definition video, the traditional network architecture based on TCP / IP has huge challenges in terms of availability, mobility, scalability, security, etc., and it is difficult to meet the requirements of current network development. [0003] Content-centric networking (CCN) is considered to be an effective way to solve existing network problems. The content-centric network obtains content in a user-driven mode, and the user sends a content request, and...
