VCTCA SNA protocol requires VTAM for POWER PNETTING. Is VTAM more
efficient than TCP/IP?
You only need VTAM if you are using SNA links. If you define the CTCs as
point-to-point BCTC, then VTAM is not needed.

Subject: VCTC vs VSWITCH
I have several VSE under z/VM and PNET files around the VSE's.
I was just wondering what others think is the best way to do this.

Why use SNA at all? Use non-SNA CTCs and define the node to POWER, then
specify the vaddr of the VCTC on the PSTART.
Al
VTAM
can send more data per buffer.
And has pacing and vpacing for buffer controls.
TCP/IP was made to connect and communicate but not always at a very
large rate.

If you can work with VCTCA, then that is the way to go.
Biggest reason, lower overhead. You are communicating over "hardware".
With the IP method, you have multiple IP stacks that you have to drive with
your 390 processor(s).

I have several VSE under z/VM and PNET files around the VSE's.
I was just wondering what others think is the best way to do this. Virtual
CTC's or TCP/IP using a VSWITCH.
Any opinions?
Would my TCP/IP PNETTING ever hit a 'real' wire?
