[ee122] "Unidirectional" connections

[Lisa Fowler]

Hi all-

Your graded phase 1s should be coming to you within the next 24 hours.
 In the meanwhile, please take the time to think about and argue to
yourself why a three-way handshake in connection establishment is no
longer necessary.  I spent a good portion of my office hours
discussing this matter today and I would really like for you to
understand why it's not necessary/applicable in the unidirectional
case.  Think about this.  If you have questions, email me and let's
set up a time to talk about it before you move forward with your
project.  Understanding this detail will help to better frame the rest
of the project, even if you still choose to do something else during
connection establishment.  It's the concept that I want you to have
down pat.
