Does applying Network Characteristics in the model affect application in real-time?

@nshuuya asked:
Hello. I have a question that I was wondering. When we build the network model on the AdvantEDGE, does applying the network characteristics in the model can affect the real-time application in between the nodes? Basically I am collecting data from the router on the edge node to send it to the cloud node. Deploying the nodes on the AdvantEDGE, does that mean applying the network characteristics such as latency and data throughput can configure the router in real-time? I understand that it is a simulator but I am quite confuse whether setting up the network characteristics here were just for experimental observation on the result or it does applies to the real time network. I hope I can hear from you as soon as possible. Thank you.

Hello @nshuuya,

The values entered in the network-model are the initial values that are applied when the scenario (e.g. applications) is deployed.

Once deployed, there are several ways to change the run-time network characteristics between the applications.

1- Manual Net.Char. event

• using AdvantEDGE frontend, open the EVENT toolbar and select MANUAL events to send a Network Characteristic event
  

2- AdvantEDGE REST API Net.Char event, this is similar to the Manual method - but triggered from an external application (e.g. not the Frontend)

• event API is described here - check the sendEvent method.

3- Event replay Net.Char events, all events are recorded when running a scenario, this allow to save the events and replay them whenever required.

Using AdvantEDGE frontend:

• To save events: open the EVENT toolbar and select SAVE EVENTS - provide file name & description
• To replay events: open the EVENT toolbar and select AUTO-REPLAY then select the replay file
  

4- Automated Net. Char events - if your scenario uses geolocation, you can activate automated network characteristics so network characteristics are automatically updated based on the UE position.

• To activate open the EVENT toolbar and select AUTOMATION then tick Network Characteristics
• More details on GIS automations available here

@nshuuya,

Reading your question again, I realized that my previous answer might not address your question entirely.

The network characteristics applied by AdvantEDGE are real-time and they can effectively be measured between a client and its server.

"Deploying the nodes on the AdvantEDGE, does that mean applying the network characteristics such as latency and data throughput can configure the router in real-time?"
The answer is definitively yes, network characteristics (latency/throughput/jitter) will be experienced in real-time between all IP packets exchanged between the client and the server; we do this by controlling the network stack.

I'm not quite sure what you qualify as "the router" above.
