Network performance management solutions are supposed to make IT’s job easier, but implementing the solution can be a nightmare. IT departments just don’t have the budget or the staff to deal with traditional network performance management solutions that require software to be purchased and installed, or that demand manual software installation, configuration and upgrades. Deployment also encompasses not just what it...

Before business productivity became dependent on the Internet, smaller companies didn’t spend money on flow analysis data. Even enterprise companies didn’t invest in expensive network hardware capable of delivering flow information at the scattered remote offices. It was never a concern until the Internet became a business and personal life line – and pipeline – regardless of location size. Personal...
