Good morning jfc, 

Could you please help me understand how shared memory or an interprocess communication mechanism of some kind, HDLC, VDH, any other line control procedure, or inter-computer buss mechanisms work?

See below an extract from IEN 48.

[...] The physical interface between directly connected gateway halves is of no special importance. For monolithic gateways, it is typically shared memory or an interprocess communication mechanism of some kind; for distinct gateway halves, it might be HDLC, VDH, any other line control procedure, or inter-computer buss mechanism.


Could you recommend books and/or other resources?

Thank you so much for all your help.    

Nathalie
