Planning & Controlling WAN Capacity
All HP routers include a network traffic sampling capability called HP EASE.
EASE stands for Embedded Advanced Sampling Environment. This
sampling technology provides an in-depth, accurate representation of
network traffic without additional special equipment or set up and with
virtually no additional network overhead (less than 1/4 of 1%).
Powerful graphical applications provide the tools to analyze information on
network traffic. They are available as standalone applications or integrated
with the HP OpenView environment. With these applications, the network
administrator can:
Better manage exisiting WAN capacity—EASE applications help the
administrator identify top sources of network traffic by network
node, communicating pair, protocol, services or application. With
this information, the network administrator can work to minimize
the impact of top traffic sources by isolating them (i.e. using traffic
filters or with further network segmentation) or through better
scheduling of network activity thus avoiding the need to add costly
WAN bandwidth.
Understand network traffic trends to anticipate future capacity
requirements—This allows the network administrator to carefully
manage the implementation of additional capacity to ensure band-
width is added only when needed and in a manner that guarantees
adequate service levels to end users.
Estimate the impact of new applications and services on WAN
capacity—As new applications and services are implemented, the
network administrator can accurately gage the bandwidth require-
ments of these new capabilities to ensure a smooth rollout with the
least cost.
These applications also provide information on network health to facilitate
fast isolation and resolution of network problems. The applications capture
traffic trends in the network and warn of impending problems. This helps
ensure continuous network operation.
