On Proposing a Novel SDN-Caching Mechanism for Optimizing Distribution in ICN Networks

Abstract

Traffic reduction in network segments through cache implementations has become an important research topic due to the exponential increase in data requests through the Internet. To support these activities, high-power computing and massive storage must support the creation, retrieval, update, and deletion of large amounts of data. Duplicate requests in the segment from the same clients challenge developing flexible networks. Studies about Information-Centric Networks (ICN) propose to improve the performance of content-based networks because there is a content handling of requests for content, leading to an independent flow from each user. Such as a unicast content delivery ignores identical requests of the other users made to the same service. Therefore, many approaches use Software-Defined Networks (SDN) to provide improved network management to develop a flexible content-based network. This article proposes the PROMID architecture, characterized as an information-centric network through SDN that optimizes the bandwidth consumption in dynamic request-response connections. From the experimental results, we observed that our approach allows us to optimize 84.61% on a total of 32.000 request responses and 34.25% in latency optimization. Moreover, our method measured an increase in the transfer rate from 19.99 Mbps to 164.74 Mbps.
