““We specifically assume that fragments are transmitted from Host to Host through means of a PACKET SWITCHING NETWORK [PSN] [ROWE70, POUZ73]. This assumption is probably unnecessary, since a circuit switched network could also be used, but for concreteness, we explicitly assume that the hosts are connected to one or more PACKET SWITCHES [PS] of a PSN [HEKA7O, POUZ74, SCWI71].””
About This Quote
Source Paper: “A Protocol for Packet Network Interconnection”, 1974
The quote assumes packet switching as the default network model, noting that alternatives exist but are not needed for the discussion.
In simple terms: It states packet switching is assumed, though other models could work.
Key Takeaway
