In this talk, we introduce measurement and analysis techniques to help CDNs balance these goals.</p><p class="MsoNormal">First, we allocate resources across the distributed edge servers to jointly minimize network latency and cache miss rates, and evaluate our methods using server request logs from a commercial CDN. Second, we introduced fine-grained measurement of the end-to-end video delivery path to detect and diagnose performance problems for a commercial content provider.Finally, we dive deeper into diagnosing network problems by monitoring TCP connections directly in the network devices. </p></div></div><p class="MsoNormal"><span style="font-family: 'Garamond','serif';" data-mce-style="font-family: 'Garamond','serif';"> </span></p></blockquote></div><p class="MsoNormal"> </p></div><br></div><style><!--
