An optical device manufacturer had a requirement to demonstrate an "EMS solution that could be scaled to manage thousands of devices" to its customer. The device had only basic TL1 protocol support and didn't have support for TL1 gateway. Unfortunately "supporting TL1 gateway" feature in the device was not possible since the time frame to do the demonstration was very short. The EMS solution team came up with a creative way of using a proxy TL1 gateway - a software component that could act as a pseudo TL1 gateway. This pseudo TL1 gateway acts as a real TL1 gateway from the EMS perspective and internally manages the TL1 session for a set of devices directly via TL1 (as shown below).
Since the provider can now add a new proxy whenever it was required, the proxy TL1 gateway provided the flexibility for seamless growth in the network on an as needed basis. The proxy gateway solved the immediate need for the device manufacturer and also provided an added advantage to meet the dynamic challenges that lay ahead.
When required, the proxy gateway could also be used to do "TL1 message parsing" to reduce the load on the overall EMS server.
