Abstract: A method includes, when a passage network connecting at least one first communication entity in a first local domain with at least one second communication entity in a second local domain does not support the broadcast scheme and the multicast scheme, transmitting, by a first discovery gateway, a discovery request to a second discovery gateway, which is one of all discovery gateways connected with the first discovery gateway, in the second local domain via the passage network. Even when a passage network that does not support broadcasting and multicasting is between two communication entities, the method enables a communication entity to search for connection information about a counterpart communication entity without information required for communication entities requiring interaction on a network to connect with each other, thereby performing a function such as data exchange and service provision at a global level.

Abstract: Disclosed is a material for forming a protective layer, a protective layer employing the material and a PDP with the protective layer. Unlike conventional protective layers which employ MgO created in conditions of pressurized artificial gas, the instant protective layer uses MgO created by heating Mg and allowing it to oxidize naturally in air. The result is MgO with fewer defects that is more effective as a protective layer in many uses, such as in a PDP. The instant MgO also shows many specific spectral characteristics and contains impurities in amounts of less than about 2 ppm each. Also disclosed is a PDP which takes advantage of the advantages of the inventive protective layer.
