A system and method for providing message connectivity between a first network using a first protocol and a second network using a second protocol is described. The toners include a core and a shell. The application program may be a spreadsheet application program. If it is applied to a satellite, the present invention can be deposited on a solar energy cell substrate to form a high optical amplification so that not only the electricity required in satellite optical communications can be reduced, but also a high-speed and large capacity of data can be transferred between satellites.
