 and Infoblox optimizes service delivery of critical applications such as email 
messaging, web, and IP phone services at remote offices with automated core network 
services that offer local service resiliency, centralized visibility, and management.  
Introduction
 
Reliable core network services at branch offices are essential to maintain application availability for 
critical business processes. Even minor interruptions in Domain Name System (DNS) services may 
lead to lost transactions at a retail store or at a bank branch office, resulting in lost revenue and 
affecting employee productivity. As we continue to experience an explosion of IP addresses at the 
enterprise, IT organizations are challenged to contain costs and maintain proper address 
management for ongoing service delivery. Current solutions for providing core network services 
force trade-offs in performance and availability in order to gain easier management. 
The Cisco Application Extension Platform (AXP) and Infoblox vNIOS together offer a solution that 
automates tedious core network service tasks, reducing errors while increasing flexibility. Branch-
office network infrastructure becomes more available, more dynamic, and easier to manage, 
thereby enabling server consolidation. 
Industry Trends  
Today’s enterprises continue to see a six percent growth in branch offices. That growth means 
more remote locations serving more people, who all need core network services to get work done.  
Enterprise IT organizations continue to face pressure to extend services to remote sites without 
increasing costs. An important strategy to address this problem is virtualizing the network and 
consolidating servers at the data center. Centralizing core network services in the data center can 
create problems for end users in branch offices, compromising performance because of WAN 
latencies and making remote networks unusable when WAN links fail. This approach can have 
major implications on a business’ profitability if core network services such as DNS, Dynamic Host 
Configuration Protocol (DHCP), IP address management (IPAM), and Remote Authentication In 
User Service (RADIUS) are temporarily unavailable to regional and branch-office users.  
On the other hand, hosting core network services on general-purpose servers at each remote site 
poses security and manageability challenges
—and dramatically increases equipment and 
operational costs.
