The next-generation Internet: unsafe at any speed?
Ken Birman · Computer · 2000
Speed alone will not make future Internet applications secure. I propose a new networking isolation capability, termed a virtual overlay network (VON). Such software-based virtual networks, layered on top of physical networks, may provide the isolation that critical applications need. Although a VON offers a response to the reliability and security needs of critical applications, it would be prohibitively costly to implement using contemporary technologies. Extending an existing router feature and coupling it with well-understood group communication techniques, however, could support VONs at low cost, with good scalability.
