Starting a Session From the Host LU
An SNA IMF LU-LU session can also be initiated by an LU on the IBM
host. When the host LU initiates a session with SNA IMF, it begins by
sending a session-initiation request to its SSCP. The SSCP returns a
CINIT request, which contains the session parameters the host LU can
support. The host LU sends these parameters in its BIND request to
the LU on the HP 3000. If the HP 3000 LU accepts the BIND request
parameters, an LU-LU session is established. Figure 4-2 shows an SNA
IMF LU-LU session initiated by a user or program on the host node.
