Remote Access Over Internet Using Reverse Session-Origination (RSO) Tunnel

A system comprising media encoded with code that, when executed using hardware, implements a process including:

• receiving or generating, by a server, a user request;
• determining whether or not there is a delivery-protocol request from a client network pending at the server;
• in the event it is determined that there is no pending delivery-protocol request from the client network at the server, repeating the determining until there is a pending delivery-protocol request from the client network at the server, and
• in the event it is determined that there is a pending delivery-protocol request from the client network, wrapping the user request in a delivery-protocol response, transmitting the delivery-protocol response to the on-premises network client over a reverse session-origination (RSO) tunnel, and extracting the user request packet from the delivery-protocol response at the client network.

A system comprising:

• an on-premises client network including hardware, a firewall, and a server agent located behind the firewall;
• and
• a server including server hardware, an agent connection endpoint (ACE) located other than behind the firewall, and a server application executing on the server hardware;
• the server agent being configured for
• forwarding a client port of the client network to a server port of the server to form a reverse session-origination (RSO) tunnel through the firewall and from the on-premises client system to the server,
• wrapping payload-protocol responses in delivery-protocol requests and transmitting the wrapped payload-protocol responses to the server via the RSO tunnel, and
• extracting payload-protocol requests from delivery-protocol responses and forwarding the unwrapped payload-protocol requests to a destination on the client network;
• the ACE being configured for
• wrapping payload-protocol requests in delivery-protocol responses, and
• extracting payload-protocol responses from delivery-protocol requests.
