With the development of multimedia technology, more and more colleges and universities apply network multimedia technology in art teaching to achieve the improvement of the art teaching effect. After analyzing the application scenarios of D2D, D2D technology is combined with social networks to create a teaching classroom where teachers and students can collaborate. A communication link is established in the network classroom to facilitate the sharing of art education content. Combine the network terminal caching system to improve the cache hit rate by caching multiple identical contents. Integrate network multimedia technology into art education and examine its contribution to education. The results show that the caching effect of multimedia technology is mainly reflected in four aspects: completeness, clarity, smoothness, and speed. When the number of caches reaches 12, the caching speed of the teaching content fluctuates in the range of 0.75-0.8. When the number of caches is less than 12, the caching fluency of the content is in the range of 0.85-0.9. This study provides a new direction to promote the reform of art education, which is conducive to improving the teaching effectiveness of art education and cultivating art talents.
