IPv6 Routed-Forwarding
======================

Following sections include Throughput Speedup Analysis for VPP multi-
core multi-thread configurations with no Hyper-Threading, specifically
for tested 2t2c (2threads, 2cores) and 4t4c scenarios. 1t1c throughput
results are used as a reference for reported speedup ratio. Input data
used for the graphs comes from Phy-to-Phy 78B performance tests with VPP
IPv6 Routed-Forwarding, including NDR throughput (zero packet loss) and
PDR throughput (<0.5% packet loss).

NDR Throughput
--------------

VPP NDR 78B packet throughput speedup ratio is presented in the graphs
below for 10ge2p1x520 and 40ge2p1xl710 network interface cards.

PDR Throughput
--------------

VPP PDR 78B packet throughput speedup ratio is presented in the graphs
below for 10ge2p1x520 and 40ge2p1xl710 network interface cards. PDR
measured for 0.5% packet loss ratio.
