The increasing volume and evolving types of Internet applications have beendemanding enhanced service from the Internet infrastructure. A significant amount ofwork is in progress on the networking aspects of the Internet. To complement theseefforts, the Principal Investigator (PI) proposes to explore the issues at the serverlevel. Specifically, this proposal addresses the support for service differentiation and overload control in Internet servers.Support for service differentiation at the servers is necessary because oftwo primary reasons. First, evolving applications like e-commerce and continuous mediatransmission will be highly benefited by the differentiated service model. Second, theadoption (most likely) of some form of service differentiation (at the router level)in the next-generation Internet will demand the servers to reciprocate in theirservices. The proposed research in this context will be approached in two steps: (a)formulation of algorithms for service differentiation, and (b) evaluation of theeffectiveness and performance of service differentiating Internet servers.Overloads at the servers are unavoidable because of the bursty andunpredictable nature of the Internet traffic. Overload causes severe performancedegradation or even crashes the server. E-commerce businesses incur serious financial lossesbecause of the overloaded servers. The performance degradation of overloaded serversmay be greatly reduced by incorporating overload control mechanisms at theservers. The PI proposes to address the design and implementation of overload controlmechanisms at the application level.In general, the performance and functionality of the Internet servers willbe greatly enhanced by the adoption of service differentiation and overload controlmechanisms.The outcome of the proposed research will have a broader impact on theInternet infrastructure and on its users. Specifically, the proposed techniques willbe complementary to the efforts in the direction of the next-generationInternet, and will be helpful for the e-commerce industry. They will also facilitate thesupport of continuous media objects in the Internet. At the local level, theresearch will have a positive educational impact on the students of Michigan StateUniversity.

互联网应用程序数量的增加和类型的演变要求互联网基础设施提供更好的服务。大量的工作正在进行中的网络方面的互联网。为了补充这些努力，首席研究员（PI）建议在服务器级别探索这些问题。 具体地说，该建议解决了在Internet服务器中支持服务区分和过载控制的问题。首先，不断发展的应用程序，如电子商务和持续的媒体传输将极大地受益于差异化的服务模式。第二，在下一代互联网中采用（很可能）某种形式的服务差异化（在路由器级别）将要求服务器在其服务中进行互惠。在这种情况下，所提出的研究将接近两个步骤：（a）制定算法的服务区分，和（B）的有效性和性能的服务区分Internet servers. Overload在服务器上是不可避免的，因为突发性和不可预测的性质，互联网流量。过载会导致服务器性能严重下降甚至崩溃。电子商务企业承担严重的财务损失，因为超载的服务器。通过在服务器上引入过载控制机制，可以大大降低过载服务器的性能下降。PI建议在应用层解决过载控制机制的设计和实现。一般来说，通过采用服务区分和过载控制机制，Internet服务器的性能和功能将大大增强。建议研究的结果将对Internet基础设施及其用户产生更广泛的影响。具体而言，所提出的技术将是补充的努力，在下一代互联网的方向，并将有助于电子商务行业。它们还将促进互联网中连续媒体对象的支持。在地方一级，这项研究将对密歇根州立大学的学生产生积极的教育影响。
