Overview of MAC and PHY Layer Changes in Experimental Setup for Channels and Flow Management

This document presents an overview of changes related to Actual Physical Channels, MAC level timing, and multiple receiver configurations. It covers updates to the MAC and PHY abstraction layer, user interface modifications, and enhancements to the trace and information retrieval systems. The experimental setup is based on a single UDP flow (Constant Bit Rate) and control TCP flow, utilizing a single Cable Modem (CM) with two downstream channels and one upstream channel. Variable send rates are achieved by toggling CBR intervals, along with calculated CMTS statistics.
