Introduction to H.323 Videoconferencing • http://www.video.ja.net/323intro.pdf

From the introduction: "As the title, 'An Introduction to H.323 Videoconferencing' suggests, the document caters for a wide range of readers' knowledge and expertise. To highlight this point it was felt that not all readers would understand some of the technical terms associated with network technologies, and so terms such as bandwidth or transport layer could alienate some members of our expected readership. To overcome this, appropriate additional material has been included to aid the understanding of the less technically minded."
