I agree with Joe. Load-splitting is to me something completely
different than PPLB.
Are you sure? Just to make sure we are on the same page, PPLB
means "Per Packet
Load Balancing"
RFC1812 describes "load splitting". in section 5.2.4.5 Load Splitting.
This cisco explanation of PPLB
http://www.cisco.com/univercd/cc/td/doc/product/software/
ios120/120newft/120limit/120s/120s21/pplb.htm
seems to match right up with RFC1812 load splitting.
I think they are synonymous.
No; per-packet load balancing is one load-splitting mechanism; there
are others.
Mechanisms which group packets associated with a single flow such
that a consistent next-hop is chosen for each of them, for example,
avoid the issue that you are concerned about (that of different
packets in a single client request being delivered to different
anycast nodes).
