The EXA40 Sessionmaster is a multifunctional network appliance. It combines a layer 4 network packet broker with one or two high performance multicore CPUs (see drawing).
The EXA40 understands network protocols, not only by the port number but can also decode protocols similar to a Probe. This feature is vital to do keyword and regular expression search and to produce useful results. The Sessionmaster EXA40 Series focuses on the mobile core network, metropolitan area network (MAN), and Internet data center (IDC) big data monitoring.
