+;   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.

+; The diagram below shows how additional protocol components can be plugged into
+; the IP layer implemented by the ip_pipeline application. Pick your favorite
+; open source components for dynamic ARP, ICMP, UDP or TCP termination, etc and
+; connect them through SWQs to the IP infrastructure.
+;
+; The input packets with local destination are sent to the UDP/TCP applications
+; while the input packets with remote destination are routed back to the
+; network. Additional features can easily be added to this setup:
+;  * IP Reassembly: add SWQs with IP reassembly enabled (typically required for
+;    the input traffic with local destination);
+;  * IP Fragmentation: add SWQs with IP fragmentation enabled (typically
+;    required to enforce the MTU for the routed output traffic);
+;  * Traffic Metering: add Flow Action pipeline instances (e.g. for metering the
+;    TCP connections or ICMP input traffic);
+;  * Traffic Management: add TMs for the required output LINKs;
+;  * Protocol encapsulations (QinQ, MPLS) for the output packets: part of the
+;    routing pipeline configuration.
