| Outline of Final Research Achievements |
In this research, we propose three in-network caching methods for smooth real-time playback on streaming over Content-Centric Networking (CCN) and show effectiveness of these caching methods. The first is an in-network caching method considering playback order of content chunks. The second is an in-network caching method considering recency and frequency of content chunks access. The third is an adaptive in-network caching method using an increasing trend of playback interruption time of each user. In experimental evaluations, we showed that three proposed in-network caching methods outperform previous method in terms of reducing playback interruption time.
