scope:

The present document describes the cable access network, and progressive network access architectures that reduce the network energy consumption and the metrics required to benchmark the network and its components to support and enable the proper implementation of services, applications and content on an energy efficient infrastructure and describe measures that may improve the energy efficiency of cable access networks.

Within the present document:

• clause 4 presents the schematic for cable access network infrastructures, the evolution of the network architectures to meet consumer capacity demand and bandwidth growth and the main components of the cable access network energy consuming elements;
• clause 5 presents measurement key performance indicators to baseline and measure network energy performance;
• clause 6 explains power consumption metrics of the CAN;
• clause 7 describes and gives consideration to power metrics of field deployed access network elements;
• clause 8 describes the electrical powering of the CAN components and the distributed usage of the electrical power. This clause explains ways to improve the power consumption and benchmarking the HFC CAN plant;
• clause 9 considers the calculations to measure the data throughput of a CAN.
