Are the seda and actor models really equivalent?

Question

SEDA is essentially a collection of independent “services” that communicate with each other through queues, which can be further abstracted as messaging.

An actor model is a set of independent functions that communicate with each other through the transmission of a message.

Aren't they equivalent? Am I missing a key difference?

Answer 1

From a look at http://www.eecs.harvard.edu/~mdw/proj/seda/ they do not seem to be there. SEDA can be easily implemented using an actor model, but an actor-based application should not have anything like the SEDA steps.
