Programming Flash Communication Server by Brian Lesser

By Brian Lesser

Flash verbal exchange Server MX (FCS) offers net builders with the potential so as to add wealthy, interactive audio and video positive aspects to their websites. Programming Flash conversation Server supplies builders a leg up in this in all probability intimidating expertise. It explains how FCS can facilitate video on call for, dwell webcasts, video chat and messaging, real-time collaboration, and lots more and plenty extra.

Mobile Telecommunications Protocols For Data Networks

Cellular clients are tough speedy and effective ubiquitous connectivity helping information functions. This connectivity should be supplied by means of quite a few diversified networks and protocols which make sure that cellular networks functionality successfully, appearing routing and handoff for cellular clients. Hac proposes a accomplished layout for cellular communications together with cellular brokers, entry networks, program protocols, ubiquitous connectivity, routing, and handoff.

Queueing Theory with Applications to Packet Telecommunication

Queueing idea with purposes to Packet Telecommunication is a good advent to primary innovations and ideas underlying the habit of queueing platforms and its program to the layout of packet-oriented electric communique structures. as well as options and techniques present in previous works, the writer offers a completely sleek computational strategy according to Schur decomposition.

Gap Junctions: Molecular Basis of Cell Communication in Health and Disease

Because the first hole junction protein (connexin) was once cloned over a decade in the past, greater than a dozen connexin genes were cloned. hence, a wealth of knowledge at the molecular foundation of hole junctional verbal exchange has been collected. This publication can pay tribute to this fascinating period within the background of mobilephone communique study by means of documenting the nice strides made during this box as a result of merging of biophysics and molecular biology, of the main strong methods to learning the molecular foundation of membrane channel habit.

Principles of electronic communication systems

Rules of digital communique structures 3/e presents the main updated survey to be had for college students taking a primary path in digital communications. Requiring merely simple algebra and trigonometry, the hot variation is extraordinary for its clarity, studying positive factors and various full-color photographs and illustrations.

Sample text

So the application creates four unique user ID values, assigns one to each client when it connects, and reclaims the ID when the client leaves. • It notifies each client of its ID by calling a remote method of the client after the connection succeeds. • It updates a shared object when a client arrives or leaves so that all the other clients know who is connected and the name of each client's stream to play. The application does not use Flash Remoting to connect to an authentication database or directory server.

Example 1-2. Setting up the NetConnection myID = ""; nc = new NetConnection( ); /* setID( ) is a remote method that will be called by the server * after the client connects. Once we get our unique ID from the * server we can use it to publish our stream. text = "Online. attachVideo(cam); initUsers( ); }; // onStatus( ) is called whenever the status of the network // connection changes. It is how we know whether we are connected. text = "Cannot reach server. "; break; } }; Some time after a connection to the server is made, the setID( ) method is called by the server and its id parameter is passed as one of four strings: "guest_1", "guest_2", "guest_3", or "guest_4".

When tunneling is employed, the Flash Player works with the user's browser to poll the communication server instead of establishing a direct Player-to-server TCP connection. When RTMP is tunneled, it is known as RTMPT. As of this writing, neither the Flash Player nor FlashCom directly supports SSL. However, encryption is an option when using tunneling, because browsers support SSL and an SSL proxy can be used with the server. 7. Getting Started A free development edition of the Flash Communication Server is available from Macromedia.
