18.104.22.168.1 KeepAlive interval
KeepAlive interval is a protocol variable that may be changed by higher layers. Implementations of this protocol SHOULD interpret this variable as the maximum time interval that a higher layer can wait before it establishes with certainty whether the server has dropped out of a conversation.
The higher-level Remote Procedure Call Protocol Extensions specify usage of this in [MS-RPCE] section 22.214.171.124.1. In TCP RPC transport (ncacn_ip_tcp), the Remote Procedure Call Protocol Extensions specify that the keep-alive interval is changed. In HTTP RPC transport, this protocol variable is changed instead.
