How to simulate network performance characteristics in Matlab?

I'm working on a control application that involves sending image features to a remote computing resource. The Simulink model and the remote resource -- currently a server located in-house -- exchange messages using UDPSend and UDPReceive blocks. I want to simulate a scenario where the algorithm that processes the input features is located in the cloud and connected via the Internet. In such scenario, the message exchanges will be subject to conditions such as varying delays, bandwidth availability, packet loss, and congestion -- unlike the present working model where the message exchanges are almost instantaneous and no loss.

Can someone provide me with advice on how to realize the above goal? Which of the toolboxes offer the capabilities to achieve the same?

Thanks.
