I believe what they are referring to is:

b2b - using the VPN as a gateway between two businesses' networks (with
      one on each end, generally)

d2b - using the VPN for remote access from home, i.e. not routing an
      entire network through it (on the local end).

In the former case, both parties would generally (though perhaps not
necessarily) have a dedicated piece of hardware that handles the encrypted
tunnel, which acts as a network gateway between the two; whereas in the
latter case, you install a software client on your desktop machine, and it
handles the encryption on your machine, connecting directly to the
business's VPN box like in a client-server paradigm.
