Note that this is a highly specialized use of the term "capability" in
a recently proposed group of protocols aimed at reducing vulnerability
of packet networks to denial of service. These protocols are partly
inspired by capability systems, but the "capabilities" used in them
are not object capabilities, and are not being used for access control
in the normal sense.

So, in reference to the subject line, there are no corresponding ACL
networks. There are only networks that make little or no attempt to
address DoS at all.
