Abstract
A method for managing and monitoring communication devices in a firewall/NAT protected network from a Management system outside the firewall/NAT protected network includes periodically and at predefined events opening an http connection and transmitting a request from the respective communication devices to the Management system through a firewall/NAT installation protecting the network, and when receiving said request in the management system, transmitting instructions and data to the communication devices from the management system in a http response through said http connection.
Claims12
A method for managing and monitoring communication devices in a firewall/NAT protected network from a management system outside the firewall/NAT protected network, comprising:
- periodically and at predefined events opening a hypertext transfer protocol (http) connection from inside a firewall/NAT installation protecting the network and transmitting a request from the communication devices to the management system through the firewall/NAT installation protecting the network;
- when receiving said request in the management system, transmitting instructions and data to the communication devices in a http response through said http connection;
- and
- when one of the communication devices is connected to the network for a first time,
- opening an initial http connection from inside the firewall/NAT installation and transmitting a BOOT request through said firewall/NAT installation from said one of the communication devices,
- when receiving said BOOT request in the management system, transmitting configuration data and parameters to said one of the communication devices from the management system, said configuration data and parameters at least defining time intervals between periodical requests and events triggering requests to be transmitted from said one of the communication devices to the management system;
- and
- prior to opening the initial http connection,
- transmitting from said one of the communication devices to a DHCP server a DHCP request requesting an IP address of said one of the communication devices, and
- receiving from the DHCP server a DHCP response including both said IP address of said one of the communication devices and an IP address of the management system.
A method for managing and monitoring communication devices in a firewall/NAT protected network from a management system outside the firewall/NAT protected network, comprising:
- receiving, at the management system outside, a BOOT request originating from a communication device inside a firewall/NAT installation that connected to the network for a first time on a hypertext transfer protocol (http) connection opened by the communication device from inside the firewall/NAT installation protecting the network, and prior to the http connection being opened, the communication device transmitting to a DHCP server a DHCP request requesting an IP address of the communication device, and receiving from the DHCP server a DHCP response including both said IP address of the communication device and an IP address of the management system;
- and
- in response to receiving said BOOT request, transmitting configuration data and parameters from the management system to the communication device, said configuration data and parameters at least defining time intervals between periodical requests and events triggering requests to be transmitted from the communication device to the management system.
