Abstract
This paper discusses using a new protocol based on DQDB (Distributed Queue Dual Bus), called DQQB, or Distributed Queue Quad-Bus. The idea is to modify the backplane bus of current architecture by utilizing four busses in the backplane. One bus going in the positive y direction and one going in the negative y direction would allow multiple CPUs on the y -axis to talk to various components by requesting slots and sending data packets (in the reverse direction) reliably. The other two busses are in the positive x direction for upstream and the negative x direction for downstream. The system is inherently stochastic as the data packets may incur bit-flips due to various types of interference, but by applying network protocols for reliable data transfer, we can reduce the probability of error. Also, by redesigning the architecture to account for DQQB, we can dramatically increase our system’s throughput.
