  A protocol of quantum communication is proposed in terms of the multi-qubit
quantum teleportation through cluster states (Phys. Rev. Lett. \textbf{86}, 910
(2001)). Extending the cluster state based quantum teleportation on the basic
unit of three qubits (or qudits), the corresponding multi-qubit network is
constructed for both the qubits and qudits (multi-level) cases. The classical
information costs to complete this communication task is also analyzed. It is
also shown that this quantum communication protocol can be implemented in the
spin-spin system on lattices.
