SUMMARY:Designing Server Sets for Anycast CDN
DESCRIPTION:In recent years\, there has been growing interest in the
 effective operation of anycast Content Delivery Networks (CDN). Existing
 anycast CDNs answer the same set of cache servers (CSes) for all content
 requests without considering the geographical distribution of popularity of
 contents. It has also been reported that the appropriateness of the
 selection of delivery servers decreases as the number of servers assigned
 to the same IP address increases in anycast delivery. To solve these
 problems\, we propose a new anycast distribution method that incorporates
 the spatial locality of the popularity of content. Specifically\, we
 propose an algorithm that creates multiple CS sets consisting of a small
 number of CSs and assigns the optimal CS set to each content by minimizing
 the number of CSes in the CS set. The algorithm aims to reduce the
 dispersion of delivery delay by minimizing the number of CSes in the CS
 set\, while covering a wide range of countries. Using a genetic algorithm\,
 we construct CS sets that incorporates spatially biased ASes and verify its
 effectiveness through computer simulation. Numerical evaluation results
 show that the proposed method can effectively cover ab out 80% of requests
 of highly popular content with about 15 ASes. It is expected that the
 proposed method can effectively cover the requirements for most of the
 contents with a small number.\n\nShort bio:\nNoriaki Kamiyama received his
