; 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.
