Far-Reaching Benefits
The nGenius Integrated Agent, when deployed with nGenius Performance Manager, offers tangible benefits over
using a traditional hardware-based probe for monitoring branch-office environments. The benefits are discussed in
the following sections.
Low Total Cost of Ownership
Because the nGenius Integrated Agent is hosted on Cisco ISRs using either a Cisco Services-Ready Engine (SRE)
or Cisco Enhanced Network Module (NME), which have their own processors, storage, network interfaces, and
memory that operate independently of the host router resources, it reduces both capital expenditures and operating
expenses of monitoring the branch office:
●
Reduces hardware and cabling costs: Piggybacking off the Cisco ISR eliminates the need for a dedicated
hardware probe, cables, power cords, and network interface cards (NICs), reducing the cost of deployment by
up to 65 percent over an entry-level hardware probe.
●
Lowers power, cooling, and space costs: Unlike hardware-based probe appliances, Cisco SRE modules do
not take up any additional physical space, freeing rack space in the branch office. Also, Cisco SRE modules
are highly energy-efficient, consuming only a fraction of the power required by typical branch-office servers
and appliances.
●
Decreases field deployment costs: The Cisco SRE is a services-ready deployment model that enables
remote provisioning of the nGenius Integrated Agent on the modules at any time, shortening the time to
deploy and eliminating travel expenses to the branch office.
●
Reduces troubleshooting expenses: The ability to capture packet data locally at the branch-office level means
that IT organizations can troubleshoot a vast majority of problems on the branch-office WAN or LAN from the
data center without having to dispatch a technician or a portable protocol analyzer to the site, saving travel
costs and reducing productivity loss of the technician due to time out of the office.
Operational Efficiency in the Branch Office
Real-time monitoring of the WAN and branch-office LAN, centralized analysis of multiple nGenius Integrated Agent
devices simultaneously, and on-demand packet capture improve operational efficiency in the branch office:
●
Facilitates optimal network availability and user experience: Always-on monitoring of the branch-office WAN
and LAN with granular alarming facilitates troubleshooting, response-time analysis, capacity planning, service
and policy validation, and analytics and intelligent early warning.
●
Speeds and simplifies remote troubleshooting: Centralized access to branch-office network and application
performance data and on-demand packet capture of both the WAN and local LAN minimize the need for
technician or device dispatch, accelerating problem resolution and reducing network downtime.
●
Aids capacity-planning activities: Having factual information on which to base upgrade decisions empowers
the IT organization to optimize the service-delivery environment by taking better advantage of existing
investments and to roll out new services with confidence. The nGenius Integrated Agent provides granular
insight into which applications are using a given link, whether or not those applications are business-related,
when those applications are active, what QoS category they are assigned, and who is using those
applications.
The nGenius Integrated Agent is not just a WAN capacity-planning tool, however. Because the nGenius
Integrated Agent has two monitoring interfaces - the primary interface for the WAN and a secondary interface
for the LAN - IT managers can observe the branch-office LAN to see how changes in Fast Ethernet traffic and
associated growth in demand affects the need for Ethernet aggregation or 1 Gigabit Ethernet.
