Core network services are essential for all networks and applications. Put simply: without core network services, IP-based networks and applications grind to a halt. They provide the "glue" that binds networks, users, devices, applications, and policies.
IP networks and applications are increasingly dependent on core network services and the interchange among them. For example, Microsoft's Active Directory makes extensive use of DNS to function correctly. Voice over IP (VoIP) depends upon DHCP and TFTP in order to work. Secure wireless access requires RADIUS for 802.1X authentication. Network Access Control (NAC) requires tight integration between RADIUS and DHCP. And most modern applications-including e-mail, ERP, CRM, and all web-based applications-are heavily dependent on DNS. The importance of core network services is poised to increase even further due to the growth in IP-enabled devices-such as RFID systems, VoIP handsets, wireless devices, etc.-and the advent of new requirements to support mobility, convergence, security, and compliance.
Legacy core network services solutions (software on servers) do not support the demands of today's applications and networks and the people who run them.
