Key Benefits
Genuine Channels provides a bidirectional link via connections opened by client applications. You will be able to deliver events and invocations to client applications even if they are behind NAT, firewalls, and web-proxy servers.
Native TCP and HTTP channels use one TCP or HTTP connection for ferrying calls only in one direction. If you want to invoke client’s object from the server, the server must connect to the client’s port. That is, if your server needs to inform several clients or a specific client about an event generated by the server itself or by any connected clients, then a TCP or HTTP connection is opened from the server to every client. Thus a client has to listen to the specific TCP port and open additional connections in order to receive calls from the server. This scheme spawns firewall, NAT and proxy-related problems because such connections are usually denied by default.

With Genuine Channels you will not have any problems with NAT, firewalls, and web-proxy servers. You will safely receive the server’s events even if a client application is thousands of miles apart and get access through a proxy requiring authorization.
Genuine Channels has the Broadcast Engine that greatly simplifies implementation and management of events. The Broadcast Engine hides event raising; you call the usual object and every invocation of this object will be delivered to all subscribers. Broadcast Engine has a powerful mechanism for tracking event delivery and timeouts, for analyzing event results, and the filtration of recipients. The implementation is very efficient; the message is serialized only once and then sent concurrently and asynchronously. In addition, the Broadcast Engine transparently supports IP Multicasting, which greatly reduces the traffic and load on the server.
Imagine that you have several clients connected to a server and you want to send the same message to some or all client applications. There is, in fact, no efficient implementation based on native channels since the native channels always send requests synchronously. That is, either you have to have a thread per client while you deliver the event, or you must invoke all client applications one after another. Having one thread per invocation is unacceptable on the server side. Consecutive invocations are slow, so the server and all clients will suffer from any client application having problems with the connection.

Even though raising events is not easy in a distributed environment, Genuine Channels provides a viable solution to implement this quickly and reliably.
Genuine Channels provides the Shared Memory Channel that uses memory shares providing the fastest possible connection. The Shared Memory Channel supports synchronous and asynchronous operations and has a complete set of features provided by the Genuine Channels solution.
Sometimes you may need to use services hosted on the same computer. Using native channels is inefficient since the traffic will go via a TCP connection. Using COM objects is more sophisticated and can lead to DLL hell.

Make your server work twice faster with the Genuine Shared Memory Channel! Enable client-server functionality without a network!
Genuine Channels provides a very reliable system of channel events that eliminates these problems completely. If the server has been restarted or has lost the state of the client application, you will know it immediately. In addition, an end-user can quickly understand what has happened if you display the status of the connection.
Using native channels, how is it possible to determine that a connection to the server is not available anymore? How can you tell whether the server has been restarted? How do you know if the server still remembers the current client and it will receive the server’s events? The only way to implement this with native channels it to poll the server constantly, asking, “Do you still remember me?!”

In addition, an end-user can quickly understand what has happened if you display the status of the connection.
You need guarantees that the server is behaving as expected — that it was not restarted or shut down. Genuine Channels give you these guarantees. You will be able to react to network events quickly and efficiently.
Genuine Channels allows you to specify different options for your invocations. You can apply compression, different security options, timeouts, and invocation modes to some or all invocations as needed.
You may want to perform different business operations with different network options and content processing features. This can include the use of compression, security services, invocation modes, and invocation parameters. There is no easy way to apply invocation options for particular invocations with native channels.

An efficient client-server application must rule its actions. Genuine Channels provides a wide range of controlling options.
Genuine Channels recognizes changes in server behavior by controlling the connections. For example, if a connection is broken, it is necessary to check whether the server is available and whether it has been restarted. No messages are lost if the connection is successfully reestablished. If the connection cannot be reestablished or a remote host has lost the state, you will know about this through Channel Events.
Native channels have the peculiarity of opening one connection per invocation. Establishing each connection takes additional time, CPU and network resources. In addition, native channels do not care why the connection was lost, despite the fact that it is the shortest way to recognize a change in the state of the server.
Genuine Channels uses the Persistent Connection Pattern by default. In this connection mode, a single connection is established by the client application and is used as a bidirectional link. This improves performance because the network layer operates with IP packets, not connections. The fewer connections you have, the fewer IP packets you need to send.

Genuine Channels uses network resources efficiently. With Genuine Channels there is no need to worry about missing important application events.
Genuine Channels provides the full spectrum of security services including encryption, content integrity checking, content signing, impersonation, delegation, and custom authentication. You can create and use different politics concurrently and independently. Genuine Channels provides the technology to authenticate a user without sending a password through the network.
Native channels provide only rudimentary security options. You will have to write your own sinks and will find it difficult to customize security at runtime. Framework 2.0 is a step up but will not fix the entire situation.

Genuine Channels answers all these questions. The collection associated with a particular remote host is called Client Session and is available anywhere you need it. The URI assigned to each host turns each remote host into a server. Since a client application gets connected to the server application, there is virtually no difference between them!
How will you know whether the user has passed authorization? How will you keep information related to a remote host and fetch it every time a client makes a request? What about data compression? How will you invoke services on the client side?

With Genuine Channels you can really use .NET Remoting, not merely accommodate to it. You can continue using all the concepts implemented in ASP.NET and other client-server methodologies without reinventing the wheel.
Genuine Channels supports different modes of Thread Pool usage which avoids this and similar problems completely.
Initially Completion Ports were designed to load all available CPUs as efficiently as possible. However, if a working thread must wait for a device or network information, the CPU is being not used. To avoid this situation, the .NET Framework creates several working threads per CPU, but their number is always limited. As a result, if a server performs any long-duration actions or talk with client applications, there is a chance that all working threads will be exhausted causing the server to stop working.

The Thread Pool issue can create difficulties. But not for you when you use Genuine Channels.
Genuine Channels provides logging of network and channel events through its built-in logging system and channel event system. Each exception fired by Genuine Channels contains all the details of the problem and has a unique type and error identifier. And Genuine Channels is distributed with source code. You will not be left guessing at unpredictable situations.
Once you have a client-server solution, you need to stay informed about processes taking place on both client and server. If problems arise, you need to know what steps are necessary to reproduce them. You might need to know how the server behaved while you were absent. The native channels do not provide any reasonable network logging capabilities, tracking of invocations, or problem details. And you do not have the source code for native channels. You will not be able to walk through the execution path to understand what happened and why.
