演講題目:On Improving User-Experienced Service Quality in Data Center 

                                      Networks

演講摘要:Since one major origin of transmission delay is the lack of external and

           internal bandwidth, many data center network researches focus on improving

           the network throughput. However, our work did not follow their idea but

           started by investigating the underlying reasons of the depletion of user-perceived

           service quality to fulfill the true requirements of users. That is, the most concerned

           service-quality factors [2] to cloud service users, including (1) the latency of

           services, and (2) the quality of results, should both be the ultimate research goals

           of researchers. We noted that, although the first factor was known by industrial

           researchers, the second factor was mostly never been deeply investigated.

           Therefore, we conducted experiments with real-world data, and observed that

           for a query, a server often generates only a small number of relevant documents, i.e.,

           higher similarity to the query, and others are not.
