[ndnSIM] Consumer without predefined interest rate

Hi guys,

just to add something to Sabet’s response:

The way to achieve that (i.e., full link utilization) can partially be through your application (in the sense that your application should send enough Interests to retrieve enough data), but one should also consider the forwarding strategy. 

As far as the application is concerned, one can use some of the alternative applications and retrieval models that come with ndnSIM (zipf, batches etc.) or write their own retrieval models.

As far as the strategy is concerned, it should estimate the link bandwidth and expand Interest forwarding to alternative links when the current link is fully utilized. To achieve that, one should write their own strategy.

However, a quick and dirty way to fully utilize a topology link in ndnSIM (given that one knows the link capacities in advance) is through the application by selecting the appropriate Interest expression rate.

Hope that this helps.
