RFC 1633 (Integrated Services in the Internet Architecture)

RFC 1633 introduces Integrated Services (IntServ) in the Internet, a framework designed to ensure reliable delivery of data for applications that require consistent performance, like video streaming or online gaming. It allows different types of traffic to receive specific levels of service, prioritizing important data packets. IntServ requires routers to manage resources along the data path, guaranteeing bandwidth and minimizing delays. This model helps meet the needs of applications that cannot tolerate interruptions or fluctuations, ensuring a smoother and more predictable user experience on the Internet.
