The transport channel is the bottom-most channel of the WCF stack. The protocols that are typically used in this channel are HTTP, TCP, MSMQ, and named pipes, but WCF allows application developers to use other transports as well, such as Simple Mail Transfer Protocol (SMTP) or File Transfer Protocol (FTP).
