# D-STREAMON: from middlebox to distributed NFV framework for network monitoring

## TL;DR

D-StreaMon is a distributed NFV framework for network monitoring that evolves the traditional StreaMon platform from middleboxes to virtual network functions, addressing scalability and latency challenges in modern cyber-threat environments.

## Contribution

It introduces an NFV-capable distributed framework, D-StreaMon, that migrates the existing StreaMon platform to VNFs for enhanced scalability and flexibility in network monitoring.

## Key findings

- Successful migration of StreaMon to VNFs
- Enhanced scalability and flexibility demonstrated
- Framework addresses complex, distributed threats

## Abstract

Many reasons make NFV an attractive paradigm for IT security: lowers costs, agile operations and better isolation as well as fast security updates, improved incident responses and better level of automation. On the other side, the network threats tend to be increasingly complex and distributed, implying huge traffic scale to be monitored and increasingly strict mitigation delay requirements. Considering the current trend of the net- working and the requirements to counteract to the evolution of cyber-threats, it is expected that also network monitoring will move towards NFV based solutions. In this paper, we present D- StreaMon an NFV-capable distributed framework for network monitoring realized to face the above described challenges. It relies on the StreaMon platform, a solution for network monitoring originally designed for traditional middleboxes. An evolution path which migrates StreaMon from middleboxes to Virtual Network Functions (VNFs) has been realized.
