[c-nsp] Packet fragmentation methods for QoS

[Everton da Silva Marques]

The task at hand is to compare packet
fragmentation mechanisms for breaking
down large datagrams so to guarantee
low latency for prioritized voice packets
carried over somewhat slow WAN links.

The classical Cisco scenario for
network providers seems to be to
run CBWFQ+LLQ+MLPPP/LFI at 
provider/customer edge.

May anyone recommend an alternative
method than MLPPP/LFI for packet
fragmentation at provider/customer
edge?

Has anyone performed testing with
reducing MTU size at WAN links in
order to make the edge routers
(both PE and CE) to break down
large datagrams? How does it
compare to LFI?

Any pointers appreciated.
