In this paper, we generalize the line-communication model by relaxing the notion of conflictness between paths. We show that the problem of finding optimal schedules to route any set of messages under both our generalized line-communication model and the bufferless routing model is NP-hard even if restricted to binary trees. Finally, a simple offline 2-approximation algorithm for our model on trees is presented.
