Just have a look at the paper of SASHA. SASHA dispatcher is implemented
in user-space, which is good for portability, but the performance is not
good. And, the tokenbeat protocol is developed for high availability.

Actually, the VS/DR (Direct Routing) forwarding method is similar to
that Layer 2 forward. The VS/DR doesn't change IP packets but send the
data frame to the selected server using the server MAC address.
Or, do you mean setting a list of server MAC addresses in the
dispatcher, instead of getting it using ARP?
