Hi @all,
I've conducted some fast failover tests on a SDN infrastructure, whereby
following three configurations were used for the device under test (DUT):
- Intel 82574L with default driver e1000e
- Intel 82574L with DPDK
- Realtek RTL8111/8168/8411 PCI Express with default driver r8169
There were two paths connected to the DUT, e.g. Path 1 and Path 2.
So by default Path 1 had been used. When Path 1 was disconnected, the
time it took to switch to Path 2 had been measured by counting the lost
packets.
Several tests have been conducted and the median calculated.
Terminology:
Median FF: Median fast failover time / ms
Median LP: Median lost packets / packet(s)
Median FF Median LP
DPDK 1700 3363
Intel 350 690
Realtek 350 695
Anyone an idea why DPDK is so "slow"?
Best regards,
Stefan.
