An asset management system is presented. The management system includes monitoring devices able to provide asset data across firewalls without requiring reconfiguration of the firewalls. The asset data pass through a forwarding service that instantiates a virtual tunnel comprising a communication channel between the monitoring devices and remote asset management engines. The asset management engines can also be located behind firewalls. As the management engines aggregate asset data, the engines can present one or more alerts via a management interface.

Asset management via virtual tunnels

A method, apparatus, and system are described for a central station to allocate virtual IP addresses. A device service manager server (DSM) has a network access module conFigured to cooperate with two or more device service controllers (DSCs). The DSM serves as a central management station for allocating and assigning Virtual IP addresses to network devices to proxy communications for networked devices on a local area network (LAN) where each DSC resides. The DSM is located exterior from the network devices on the LAN where communications associated with the assigned VIP addresses are being routed to. The DSM assigns a Virtual IP Addresses to each DSC and establishes a route from the assigned Virtual IP address to a destination network device on a LAN, based on corresponding DSC and network device information stored in a registry of the DSM. In some embodiments, a return route from the destination network device back to the network device on the LAN with the assigned Virtual IP address may also be established.

Method to tunnel UDP-based device discovery

A method and system that allows a host system application to securely communicate with a legacy device is provided. A redirector software module receives data that is destined for a host system serial COM port. Data is secured and re-directed to a legacy device via a network port instead of the serial COM port. Conversely, data destined for the host system is provided to a device server via a server COM port by the legacy serial device. The data can be encrypted and sent to the host system via the network. The redirector software module decrypts the encrypted data and presents it to the consumer application as if the data had arrived via the local COM port.

Secure communication port redirector

A device server intended for attaching serial devices to a network includes Ethernet communications, an Ethernet switch, and serial communication capability so that multiple device servers are connected in a 'daisy chain' or series pattern. Galvanic isolation of the power supply from the housing and communication ports, screw terminal and modular connections, DIN rail mounting, broad power supply voltage ranges or 'Power-over-Ethernet' and operator visible indicator lamps with a pulse stretching feature greatly simplify installation and use.

Daisy chaining device servers via ethernet

A PCB mountable module includes logic circuitry that translates between serial and wireless communication protocols. Supported standards include I2C, CAN, ProfiBus, SPI, and USB, IP, ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP. Modules can optionally provide security, MILARRS functionality, and web related services such as email alert. The novel modules can be used wherever a device designer wants a plug-in (or 'drop-in') system that obviates the need for independent development and maintenance of wireless capability. Examples include servers, desktop and laptop computers, and even devices such as kitchen appliances with relatively simpler electronics.
