Directory server for automatic network information access systems
View Patent ↗Systems, apparatus and methods are described for providing information access to network devices. A directory server registers identification information about a first network device coupled to a first network. The first network and the directory server may be coupled to a second network, which may include a wide area network, public network, or the Internet. The identification information may include a network address of the first network device on the first network, or a network address of the first network on the second network. The directory server may receive and process requests for identification information about registered network devices, and may selectively reply to the requests based on status information of the first network device.
1. A system for controlling access to a printing environment comprising:
a directory server coupled to a first network via a first router, wherein said first router enforces a first firewall, the directory server comprising:
a memory; and
a message processor configured to register identification information in a directory table in the memory;
at least one handheld mobile device coupled to a second network comprising a wide area network (WAN);
at least one printing device coupled to a third network comprising a local area network (LAN) via an additional router, wherein said additional router enforces at least one additional firewall, wherein the LAN is configured inside at least one additional firewall, wherein the directory server is configured outside the at least one additional firewall, wherein said at least one printing device is configured to print at least one file from said at least one handheld mobile device only after receiving necessary configuration information, and wherein said LAN and said WAN network operate using non-homogeneous communication protocol;
wherein the directory server message processor is configured for automatically registering identification information having a communication protocol for the at least one printing device on the directory server without intervention by an administrator, wherein the identification information at least partially comprises availability information and configuration information;
wherein said at least one handheld mobile device is configured to send a discrete request, via an additional communication protocol that is different than the first communication protocol, to the directory server, said discrete request comprising an availability inquiry about the printing-availability of said at least one printing device;
wherein the directory server message processor is configured for processing the discrete request, regardless of whether the discrete request comprises the first communication protocol or additional communication protocol, and issuing a discrete reply message to the at least one handheld mobile device, wherein the discrete reply message comprises all the configuration information necessary for the at least one handheld mobile device to configure the at least one printer to print files from the at least one handheld mobile device without intervention by an administrator.
2. The system of claim 1 , wherein the at least one printing device is selected from among an inkjet printer, a laser printer, a wide format printer, and a dot matrix printer.
3. The system of claim 1 , wherein the network device further comprises a network connection for coupling to the first network.
4. The system of claim 1 , wherein the identification information comprises an address.
5. The system of claim 1 , wherein the identification information comprises an address of the network device on the first network.
6. The system of claim 1 , wherein the first network is coupled to a second network, and the identification information comprises an address of the first network on the second network.
