Abstract

Software engineers used to have a hard time developing real-time and interactive Web applications, Most of such software requires high and stable throughput, a prerequisite which the Internet's best-effort service does not provide. Hence, a large body of effort has recently gone, and is currently going, into modifications to the Internet architecture. Software engineers should closely monitor this research, and leverage new technologies to build applications that get the most from the Web.This study explains how the Internet Engineenng Task Force's (IETF) working groups IntServ and DiffServ seek to transition the Internet into a robust platform for high quality of service. It elaborates on the Resource Reservation Protocol's (RSVP) method of procedure to reserve bandwidth and buffer space in IP routers along a data flow's sender-receiver path. It presents the Subnet Bandwidth Manager's (SBM) mapping of RSVP functionality onto local- and metropolitan-area networks that use a shared medium. Furthermore, it discovers a way to implement demanding, yet adaptive, Web applications that are content with traditional best effort. The paper concludes with the Common Open Policy Service (COPS), a framework for policy decision-making and enforcement.
