Aim of this paper is to study the complexity of the Deadlock-Safety problem for Store-and-Forward networks. The following results are shown: 1. the problem is in general NP-complete, even for tree-like networks. It is still NP-complete for various "simple" topologies (including bipartite, grid and two-terminals series-parallel graphs) when each vertex buffer is of unit capacity; 2. the problem is solvable in PTIME for 1-buffer tree-like networks.

Abstract
Aim of this paper is to study the complexity of the Deadlock-Safety problem for Store-and-Forward networks. The following results are shown: 1. the problem is in general NP-complete, even for tree-like networks. It is still NP-complete for various "simple" topologies (including bipartite, grid and two-terminals series-parallel graphs) when each vertex buffer is of unit capacity; 2. the problem is solvable in PTIME for 1-buffer tree-like networks.File in questo prodotto:
