It relies on XML Information Set for its message format, and usually relies on other Application Layer protocols, most notably Hypertext Transfer Protocol (HTTP) or Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission.
The Application Layer Gateway service in Microsoft Windows provides support for third-party plugins that allow network protocols to pass through the Windows Firewall and work behind it and Internet Connection Sharing.
The ControlNet application layer protocol is based on the Common Industrial Protocol (CIP) layer which is also used in DeviceNet and EtherNet/IP.
The protocol layers are designed to integrate with any application layer, but the presence of a management interface suggests a design targeted to DLMS/COSEM, a widely used EU standard for the application layer of meters and SCADA.
Examples of application layer protocols include the File Transfer Protocol (FTP), the Simple Mail Transfer Protocol (SMTP), and Dynamic Host Configuration Protocol (DHCP).
The Mobile Application Part is the application-layer protocol used to access the Home Location Register, Visitor Location Register, Mobile Switching Center, Equipment Identity Register, Authentication Centre, Short message service center and Serving GPRS Support Node (SGSN).
