Advantages
A benefit of implementing multiple services over a message abstraction layer is that it is easier to bind these to different underlying technologies and protocol encodings. All that is required is an ‘adapter’ layer between the MAL and the underlying protocol to enable all services over that technology. Hence the same service can be implemented over ground-based network technologies and middleware, or it could even be carried across the space link itself. The services themselves provide the ‘plug-and-play’ interface for applications, allowing them to be integrated and deployed wherever is appropriate for the mission.
There are no performance overheads as the MAL layer is conceptual and can be optimized out using code generators .

Famous quotes containing the word advantages:
“No advantages in this world are pure and unmixed.”
—David Hume (1711–1776)
“Can you conceive what it is to native-born American women citizens, accustomed to the advantages of our schools, our churches and the mingling of our social life, to ask over and over again for so simple a thing as that “we, the people,” should mean women as well as men; that our Constitution should mean exactly what it says?”
—Mary F. Eastman, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4 ch. 5, by Susan B. Anthony and Ida Husted Harper (1902)
“To say that a man is your Friend, means commonly no more than this, that he is not your enemy. Most contemplate only what would be the accidental and trifling advantages of Friendship, as that the Friend can assist in time of need by his substance, or his influence, or his counsel.... Even the utmost goodwill and harmony and practical kindness are not sufficient for Friendship, for Friends do not live in harmony merely, as some say, but in melody.”
—Henry David Thoreau (1817–1862)
