Abstract: This disclosure relates to determining aggregate energy consumption associated with sending content (e.g., media content, such as a video file, audio file, etc.) across a network. For example, node 106A receives a network packet from server 104 and forwards the packet to node 106B. Node 106A determines an amount of energy consumed by node 106A in processing the packet. Node 106A adds this determined energy consumption value to an energy consumption value in a header within the network packet to produce an aggregate energy consumption value and send the network packet with the aggregate energy consumption value to node 106B. Node 106B receives the network packet from node 106a. Node 106B determines an amount of energy consumed by node 106B in processing the packet.
