A strategy for synchronising simplex message streams
J. M. McCaig · ACM SIGCOMM Computer Communication Review · 1991
In information networks which, for example, employ satellites or LANs with broadcast or multi-cast capability, data flow is often simplex. Various quality of service improvements are possible by using redundant network capacity, which is intended for "fail-over", to carry duplicate message streams instead. This paper examines a strategy for synchronising message streams delivered via diverse but unreliable routes, and illustrates it with a Pascal procedure called Y.
