Chapter 13 Notes
The session layer establishes,
manages, and terminates, sessions between aplications.
TCP provides sequencing of segments
with forward reference acknowledgment.
If a sequence number is missing
in the series, the segment is retransmitted.
A decision the session layer
makes about wether to use 2 way simultanious or 2 way alternating (The
two major forms
of of dialog control.)
2 way Alt. (Half Dulpex) is
when turns are taken, Simultanious (Full Duplex) is when messages are sent
in no particular
2 Way Alt. & 2 way Simmultaneous Communication
2 way alt communication avoids
interupts by taking turns simelar to token ring.
2 way simultanious allows
2 messages to cross during conversation.
Dialogue seperation is the orderly
initiation, termination, and managing of communication.
