Design Considerations
One important factor to be minimized is the connection establishment delay. This is the time from when the user first attempts to make a connection to when the receiving computer begins to receive information. This delay can range from 3 to over 20 seconds depending on various factors. These include but are not limited to the type of physical cable used in the connection, the distance the data is being sent, and the protocols used to send the information. Knowing the extent of the delay is a very important part of designing an efficient DDR system. If the delay when attempting to establish a connection is too great, the application will abandon the connection attempt and try again.

Famous quotes containing the word design:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
