I highly recommend you look at Figure 6 in the CICM Logical Model: http://tools.ietf.org/html/draft-lanz-cicm-lm-00#section-5 I've reproduced it here. Security Domain Security Domain Boundary Boundary . . +--------.--------+ +--------.--------+ Client --(a) Cryptographic (b)---(c) Cryptographic (d) -- Client Program X | Module | | Module | Program Y +--------.--------+ +--------.--------+ . . X local X remote Y remote Y local port (a) port (b) port (c) port (d) Figure 6. Local and Remote Port Nomenclature for Channels that Operate in Two Security Domains The terms remote/local are relative to the client program. We chose these terms to avoid directionality (e.g., input / output) because the direction depends on the operation (e.g., encrypt / decrypt), but we need to specify the ports consistently (regardless of the operation). Let me know if this needs more elaboration.
