Lectures notes for 2010 - KTH

Implicit vs. Explicit Information
Van Jacobson expresses this as:
• "The nice properties of packet switching result from moving source &
destination information implicit in a circuit switch’s time slot
assignments into explicit addresses in the packet header.
(But its easy to do this wrong, e.g., ATM.)
• The nice properties of dissemination result from making the time &
sequence information implicit in a conversation be explicit in a fully
qualified name."
