Abstract

An Internet-based method of and system for monitoring, configuring and servicing planar laser illumination and imaging (PLIIM) based network remotely situated from and using any Internet-enabled client computing subsystem functioning as the network management station (NMS). The PLIIM based network (i) has a plurality of nodes, (ii) is operably interconnected to the infrastructure of the Internet, (iii) has set of parameters related to network, system and/or subsystem characteristics of said PLIIM-based network, and (iv) is capable of performing a predefined set of object identification and attribute acquisition functions in a network environment. The method comprising using the NMS to remotely monitor the set of parameters related to network, system and/or subsystem characteristics of the PLIIM-based network. The NMS, its supporting client machine, and/or remote servers supporting servlets, analyze the monitored parameters so as to diagnose either actual or potential performance failures in the PLIIM-based network which might prevent the performance of one or more of the predefined set of object identification and attribute acquisition functions. By virtue of the present invention, it is now possible to remotely monitor, configure and service Internet-based PLIIM-based networks simply using any Internet-enabled browser, thereby keeping such networks up and running, with minimal down-time.
