Channel components are the heart of RemObjects SDK. They connect your client applications and your server applications by sending Messages back and forth, to submit a request, return a response, fire a callback event, etc. No matter what type of application you are building with RemObjects SDK, channels will be an integral part of it.

To accommodate for a wide variety of scenarios and provide flexibility, RemObjects SDK includes a pretty extensive list of channel components, which in some cases might be difficult to choose for the novice user. See the RO38 article for a brief overview of all available channel types.

Note: for historic reasons, the RemObjects SDK for Delphi class library uses the terminology "Channel" for client channels and "Server" for server channels, while the .NET edition properly refers to "client channel" and "server channel". Besides these naming differences, the same concepts apply for both platforms.

Commonly Used Channels

• HTTP Channel – flexible and network independent communication using the World Wide Web's Hypertext Transfer Protocol (HTTP)
• Super TCP Channel – sophisticated and flexible two-way communication between clients and servers
• Super HTTP Channel – combining the flexibility of HTTP withthe power of the Super TCP Channel

Frequently Used Channels

• Legacy TCP Channel – lightweight communication over raw TCP
• Local Channel – direct communication within the same application.

Rarely Used Channels

• Email Channel – asynchronous communication over existing email infrastructure (Delphi only)
• UDP and Broadcast Channels – lightweight packet based communication (Delphi only)
• Named Pipe Channel – inner-LAN communication without TCP/IP network protocol
• WinMessage Channel – inter-process communication without network on a local computer (Delphi only).
