  LU6.2 (APPC) over IP? 
 The Question is:
 
Is it possible to run LU6.2 (APPC) over TCP/IP?
Currently we have an application which sends and receives data from an IBM host
 (CICS) via LU6.2 SNA connection.  The application runs on a VAX in a DECNET
 environment and communicates to the IBM system via an SNA gateway.  We would
 like to eliminate the
gateway and run the application over a TCP/IP network.  The IBM machine
 supports LU6.2 over TCP via the VTAM ANYNET product.  Is there software
 available for the VAX/VMS environment which will allow us to do this
 (preferably without having to change the e
xisting application code)?
 
 The Answer is :
 
  This function is defined by the MPTN (multi-protocol transport networking)
  architecture, and provided in the AnyNet/MVS product.
 
  The AnyNet product is not "SNA over TCP/IP", it provides a way of running
  the LU6.2 protocols (i.e. session/presentation services) over a TCP/IP
  transport network connection.  If you want APPC over an IP network, then
  you need to run a higher layer protocol -- like LU6.2 -- on top of TCP,
  as TCP is simply a reliable byte-stream network transport.
 
  The BEA MessageQ, IBM MQ Series and related middleware products might
  be of interest here.  The Compaq SNA APPC/LU6.2 Programming Interface
  for OpenVMS (V2.4 is current as of this writing; see SPD 26.88.xx) will
  be of particular interest.
