Passive OS image loading for POS devices

Disclosed is a method for passive operating system (OS) image loading for point of service (POS) devices.

The retail industry is typically a three layer architecture with a central office, a store server and multiple cash registers. In a typical retail scenario, operating systems for the cash registers are made at the central office. These images will then be pushed to the store servers. Store servers in the branch serve as a local repository for these images. In most stores, these store servers are low end hardware or even another cash register itself serving a dual purpose. When all the cash registers in the store boot, they download the image from this single store server. Downloading such images takes lot of time and puts a stress on the server because of the size of these images. This results in more time for the cash registers to boot. So start time of the cash registers varies depending on the stress on the server. To ease this problem, the existing solution employs multi-casting and means of a client to join in the middle of a transmission. Clients continue from that point in the transmission and later download the missing segments from the server. This solution doesn't completely alleviate the problem, since the image download still comes from a single server. This results in an unpredictable download time for the image.

To alleviate the daily server load, it is proposed that the network cards in the cash registe...
