We investigate the problem of broadcasting in a complete synchronous network with dynamic edge faults. The faults may be loss of messages only (omissions) or of arbitrary type (Byzantine fualts). In both cases, broadcasting can be done in at most 5 rounds, i.e. in constant time, as long as the maximal number \phi of fautls per round allows broadcasting at all. We present algorithms which are optimal for different variants of the problem.

### Broadcasting in Complete Networks with Dynamic Edge Faults

#### Abstract

We investigate the problem of broadcasting in a complete synchronous network with dynamic edge faults. The faults may be loss of messages only (omissions) or of arbitrary type (Byzantine fualts). In both cases, broadcasting can be done in at most 5 rounds, i.e. in constant time, as long as the maximal number \phi of fautls per round allows broadcasting at all. We present algorithms which are optimal for different variants of the problem.
