Management

The traditional model of device- and connection-centric infrastructure also renders network
management complex and expensive. Network administrators have to manually configure each
core routing switch and edge switch to behave a particular way for a particular client or service.
There is no specificity of network behavior based on individuals or groups with varying network

requirements. The result is a static, rigid infrastructure that, once configured, does not change
or adapt.
Nevertheless, change is an inescapable truism in the business world. With organizational and
technological needs continually evolving – new applications and network services, new edge
switches, wireless network connections, new clients that connect to the network, new
employees, etc. – companies get locked into an ongoing, time-consuming, expensive cycle of
network reconfigurations, redesigns and upgrades.
