The standards for requesting videos from a video sharing site such as YouTube would be found at the Application layer. This layer defines protocols and standards for applications to communicate with one another, and includes protocols such as HTTP, FTP, SMTP, and DNS. YouTube's API (Application Programming Interface) which allows third-party applications to interact with YouTube's services and data, is an example of an application layer protocol. The transport, internet, and data link layers are responsible for other aspects of network communication and do not typically have standards specific to requesting videos from a video sharing site.
