The sample configuration file demonstrates that network layer components such as TCP, UDP, ICMP etc, can be easily integrated into ip pipeline infrastructure. Similarily, various other functionalities such as IP Reassembly for input traffic with local destination and IP Fragmentation to enforce the MTU for the routed output traffic, can be added using SWQs enabled with reassembly and fragmentation features.

; 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.
