- The management improves the performance and the quality of the services that pass through for the WAN.
-
The Return of the investment (ROI) of the Management of the WAN é very good, pay back of the investment in otimização equipment é minor who 12 months, gotten with the reduction of the capacity of link, with the monitoramento of the SLA of the supplier of the service, with the Modelamento of the Tréfego, beyond the quantitative and qualitative improvement felt by the usuérios.
Appliances Expand the phases cover all of the process of otimização WAN, are native in all appliances the functions of Monitoramento e QoS (Quality of Service) in Real, most important, allowing to know and shape Time tréfego of the WAN, also verifying the improper uses of the WAN and if the supplier this delivering what it was stipulated in the contract of service level.

Some older protocols are of course privileged, as Ftp e HTTP, and others as VoIP, CITRIX, more modern not obté m the necesséria priority of band. The function Modeling of Band (QoS) it allows to correct this, improving the one performance sé rie of applications you criticize. The Monitoramento of net WAN, normally difficult.
