Dear Sándor,


As indicated from the EIT Digital Infrastructure pre-call workshop, I 
would like to explore potential common interests in deeply programmable 
networks.

The background is based on the FP7 UNIFY project (coordinated by 
Ericsson Hungary) and our results produced at SICS, oriented at using 
and aggregating data plane counters locally as input to low-complexity 
but sophisticated predictor models.

One of the main challenges towards programmable networks is related to 
scalable monitoring or network observability. Current OF mechanisms and 
switches do not allow for local deployment of observability points (or 
monitoring processes) which severely limits the granularity and 
usefulness of the monitoring information, among other things. Another 
challenge regards effective deployment mechanisms and implementation of 
observability capabilities in a switch with low processing overhead to 
avoid bottlenecks caused by monitoring.

So far we have developed the concept of observability points in terms of 
a light-weight low-complexity model for predicting persistent congestion 
episodes at buffer fill time, using only two data plane counters. The 
offer and interest in a potential collaboration is to take this concept 
further into implementing relevant mechanisms needed for enabling and 
supporting observability of programmable networks by flexible deployment 
of monitoring mechanisms. Being able to define and deploy observability 
points by the use of P4 and a compiler without modifying the switch 
kernel could be an interesting case and a step further.

If this sounds interesting and relevant to the project you have in mind, 
let me know and we can setup a call (or meet at the EIT PE in Brussels).

Best regards,
rebste
