I've been working some major issues with CEF/PPLB and MLPPP. Here's what
I've been able to determine:
MLPPP does interleaving that makes the bundle appear as one physical link.
The packets are sent and arrive through one IP address.
CEF/PPLB allows a per-packet load sharing through 2-6 ip addresses on each
end.
CEF/PDLS allows load sharing based on source/destination pairs. But any one
flow is limited to the bandwidth of one link and the traffic distribution is
not exactly equal.
End operating systems have to handle packet reordering from multiple source
addresses when using PPLB. Some clients, notably Microsoft, don't like this
too much and the overall performance suffers.
Of course, the router CPU overhead on MLPPP can be pretty high, depending on
the platform.
