Since, June of 1999 The Regulation of Bulk Transfer for Urban Planning has been carried out, which is tried implementing in Taipei & Taipei county until June of 2004. From July 1 of 2005, on all counties and cities implement it in an all-round way. So far, there are only two application cases in Kaohsiung city , since the examining principles have been announced. This research will probe into reference documents of TDR and all the situtations about bulk transfer in this country¡CThrough all these points of view the study aims at probing into the problems of implementing it in Kaohsiung city bulk transfer.The research approach adopts an exploratory case study, including calculating IRR with cases and interviewing real estate, officials and scholars. The goal is to get ¡§generalizing¡¨ , not ¡§ particularizing¡¨ analysis.The result of study is based on construct validity of thesis. It¡¦s analytic generalization not statistical generalization.From the sight of Kaohsiung¡¦s TOD policy we find :In policy direction, for core of the city (Cianjin, Sinsing, Lingya, Sanmin, Yencheng district), there are functions to match up the centeral government¡¦s six years plan for urban renewal.But urban renewal is the most difficult for real estate co. to invest and develop.Nowadays, outside the core of city and in the suburb, vacan lots are preferred to invest.Like this, the policy directions are not combined with the behavior of non-governmental investment.The bulk is needed in the core of city, but it is difficulty to processing. And in the second circle and suburb, there is no bulk transfer encouragement, which is not fit for the development policies.Under the circumstance against policy & both hurting public and private. It¡¦s difficult for the bulk transfer policy to make great achievements.From the reference documents and case data, we farther find that a bulk transfer case should catch with the development trend of the local real estate market in order to succeed.In interviewing , all the interviewees have the same point of view: In Taipei city and county, because of highly urban development, gathering population and high profit of real estate, the bulk transfer already extremely popular. Comparatively, in Kaohsiung city, because of industry depression, purchasing power drop, no population growth and real estate market is difficult to promote the bulk transfer policy. Because, whether the bulk receving lots can create the profit is the key point for bulk transfer to become popular.

As the Internet continues to evolve, without providing any performance guarantees or explicit feedback to applications, the only way to infer the state of the network and to dynamically react to congestion is through end-to-end measurements. The emph{available bandwidth} (avail-bw) is an important metric that characterizes the dynamic state of a network path. Its measurement has been the focus of significant research during the last 15 years. However, its estimation remained elusive for several reasons. The main contribution of this thesis is the development of the first estimation methodology for the avail-bw in a network path using end-to-end measurements. In more detail, our first contribution is an end-to-end methodology, called SLoPS, to determine whether the avail-bw is larger than a given rate based on the sequence of one-way delays experienced by a periodic packet stream. The second contribution is the design of two algorithms, based on SLoPS, to estimate the mean and the variation range, respectively, of the avail-bw process. These algorithms have been implemented in two measurement tools, referred to as PathLoad and PathVar. We have validated the accuracy of the tools using analysis, simulation, and extensive experimentation. Pathload has been downloaded by more than 6000 users since 2003. We have also used PathVar to study the variability of the avail-bw process as a function of various important factors, including traffic load and degree of multiplexing. Finally, we present an application of avail-bw estimation in video streaming. Specifically, we show that avail-bw measurements can be used in the dynamic selection of the best possible overlay path. The proposed scheme results in better perceived video quality than path selection algorithms that rely on jitter or loss-rate measurements.
