This handled censorship, bad cables and outages.
But who was it? I can see him in my mind...

Could you be thinking about someone running Multilink PPP? I worked for a company that made MLPPP routers in the 80s. Our use of MLPPP was not for diversity, but for dynamic bandwidth allocation. In the 80s, an ISDN connection could be bought from bell as D (16kbps), B+D (64kbps + 16kbps) or 2B+D ((128kbps + 16kbps). We could make a connection on the D channel and dynamically bring of the B channels as traffic exceeded pre-set levels. The router would bond the traffic across the three links. Oh the 80s, when bandwidth was horribly expensive! BTW, I think Cisco still makes this stuff. -- Michael Galea
