Question

IoT proxy operates in which layer?

Answer 1

The gateway is a key component of every IoT solution. Before you decide what kind of hardware you would like to purchase as your gateway platform, spend some time analyzing your message f low and the data formats of the payloads, and try to filter out or aggregate as much data as you can before sending it from the gateway to the data center. Also, while the choice of proper hardware for your IoT solution is very important, you have to keep in mind that picking up the right gateway software and management infrastructure (like the LWM2M server for managing your devices) is a factor that will highly impact the total maintenance cost of your system.

Answer 2

The OSI architecture consists of 7 layers and each layer is responsible for a certain functionality

The topmost layer is the application layer where the applications run.  

They are used to determine the protocols and methods that would be used by the host system.

They are also used in message exchange protocols.

The proxy data or proxy servers are stored in the application layer.

IoT stands for Internet of Things and its proxy operates in the application layer.

Hence, Application layer is the answer.
