Abstract:
A method for transferring data between a host that generates polling requests and a remote panel that directs status data responses to the host based upon the polling requests over a network comprising the steps of:providing a primary router between the panel and the network;providing a secondary router between the host and the network;transmitting a polling request for the panel to the secondary router;identifying, based upon the polling request, in the secondary router the host and appending to the polling request a tunnel data corresponding to the identified host and the panel being polled based upon data in the polling request, and appending network source and destination information for, respectively, the secondary router and the primary router;transmitting the appended polling request to the primary router;receiving, at the primary router the polling request and transferring the polling request, based upon the tunnel data to the panel, including storing the tunnel data and the source information for the secondary router;receiving, at the primary router from the panel, a status data response, based upon the polling request;identifying, based upon the status data response, in the primary router, the host by accessing the tunnel data stored in the step of storing and appending to the status data response tunnel data corresponding to the host, and appending network source and destination information for, respectively, the primary router and the secondary router;transmitting the appended status data response to the secondary router; andtransferring the status data response to the host based upon the appended tunnel data.
