A Study on Timely Content Delivery with FEC for Streaming Services in ICN

The demand for streaming services—such as video delivery, online meetings, and cloud gaming—has been rapidly increasing, making the preservation of information timeliness a key communication requirement. Information-Centric Networking (ICN) has emerged as a promising architecture to address this challenge by leveraging in-network caching. However, similar to IP-based networks, ICN relies on retransmissions to recover lost packets, which can introduce delays and degrade timeliness. This paper proposes a transmission scheme that integrates Forward Error Correction (FEC) techniques into ICN. In the proposed scheme, CRs on the transmission path generate FEC chunks and deliver them via a single-path or multi-path strategy. Simulation results demonstrate that the proposed scheme improves the timeliness of content delivery by mitigating the impact of retransmissions.
