1.3.1.1 Interface Manipulation
In the context of the Remote Desktop Protocol Video Redirection Virtual Channel Extension, interfaces are groups of messages with a common identifier. This protocol includes a common infrastructure for manipulating these interfaces, which is called interface manipulation. This infrastructure consists of Interface Query and Interface Release messages, [MS-RDPEXPS] section 2.2.2. A newer version of an interface can be retrieved by sending an Interface Query message. An interface is terminated by means of an Interface Release message in order to keep the number of active interfaces on the network low.
For more information about the interface manipulation infrastructure, see [MS-RDPEXPS] section 1.3.2.1.
