!!! Overview [{$pagename}] is a [Communication Layers] and conceptual division of methods in the layered [architecture] of [protocols] in the [network] stack. [{$pagename}] provides the mechanism for opening, closing and managing a [session] between [user] [application] processes, i.e., a semi-permanent dialogue. Communication sessions consist of requests and responses that occur between [applications]. [{$pagename}] services are commonly used in [application] environments that make use of [Remote Procedure Calls] ([RPCs]). !! [OSI-Model] Within the service layering semantics of the [OSI-Model] network architecture, the [{$pagename}] responds to service requests from the [presentation Layer] and issues service requests to the [transport Layer]. !!
