CNF: A Smart Network Utilization Algorithm


CNF is an innovative network scheduling algorithm for Tivoli FastBack Data Protection and Recovery. It is a consequence of collaboration between the machine learning group at IBM Research – Haifa and Tivoli's Fastback team. The algorithm, which is now a part of the FastBack product, combines intuition from machine learning and competitive algorithms. It monitors the underlying communication network, estimates some basic parameters of it, and determines the number of extra blocks to be read ahead accordingly. The result is a significant acceleration of the FastBack system; in particular, in environments characterized by high latency.
