## 6 Conclusions  
This paper presents the design and evaluation of MPTS-ICN, which achieves multipath data transmission through single-hop network node relay and significantly enhances content delivery in ICN. In our proposed scheme, ICN edge nodes split the traffic and reroute it to the destination along multiple one-hop disjoint paths established using a set of multipath service nodes. Compared with other multipath transmission methods, our proposed scheme has no specific requirements for the network settings of terminal devices and does not require modification of the existing network devices. Therefore, it is easy to implement and deploy. In order to distinguish between ordinary data packets and multipath data packets, we extend the original network layer protocol to support multipath data transmission in ICN networks. In addition, we select multipath service nodes based on the link overlap of paths and the link state of paths and assign data chunks based on the weight of paths to ensure the performance of multipath transmission. The experimental results show that our proposed scheme outperforms the best-route method by 83.6% and the ECMP method by 79.7% in average flow completion time. Therefore, MPTS-ICN is more efficient compared with existing data transmission methods in terms of bandwidth usage and transfer time.  
In the design of the multipath service node selection algorithm, this paper only considers the independence between autonomous systems to ensure the independence between paths. However, there are also rich link resources available within the autonomous system, and there may not be multiple autonomous systems in some geographical areas. Therefore, using the rich link resources within the autonomous system is one of our future research directions. In addition, the data scheduling strategy employed in this paper is currently only based on the weight of the path to allocate ICN data chunks, which cannot adapt to the dynamic changes of the path state. In future work, we will redesign the data scheduling strategy to adapt to the dynamic changes of the path state.
