+;   An edge router typically sits between two networks such as the provider
+;   core network and the provider access network. A typical packet processing
+;   pipeline for the downstream traffic (i.e. traffic from core to access
+;   network) contains the following functional blocks: Packet RX & Routing,
+;   Traffic management and Packet TX. The input packets are assumed to be
+;   IPv4, while the output packets are Q-in-Q IPv4.
+
+;  A simple implementation for this functional pipeline is presented below.
