; 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 upstream traffic (i.e. traffic from access to core
; network) contains the following functional blocks: Packet RX & Firewall,
; Flow classification, Metering, Routing and Packet TX. The input packets
; are assumed to be Q-in-Q IPv4, while the output packets are MPLS IPv4
; (with variable number of labels per route).
; A simple implementation for this functional pipeline is presented below.
