transparency, improving deployment flexibility with on-demand service
enablement, and integrating with native IOS-based services such as
security, NetFlow, and QoS.
Medianet for 2900 ISRs
As video becomes pervasive in an organization and more video devices are
used, new demands are placed on the network. It can be challenging to
accommodate video needs while reducing complexity, planning for
capacity, and providing the best possible user experience.
Smarter Network, Endpoints, and Services
Traditional IP networks need to evolve to medianets to accommodate these
changes. A medianet is an end-to-end IP architecture that helps to
enable pervasive media experiences.
The medianet architecture includes a smarter network, smarter endpoints,
shared media services, cloud services, and shared media services.
More Medianet Benefits
A medianet reduces total cost of ownership and scales video through
features such as auto-configuration and media monitoring. At the same
time, it helps to ensure a quality user experience while optimizing
bandwidth use and efficiency.
Managing Your Integrated Services Routers
Network management applications are instrumental in lowering operating
expenses (OpEx) while improving network availability by simplifying and
automating many of the day-to-day tasks associated with managing an
end-to-end network. Day-one device support provides immediate
manageability support for the Integrated Services Router, enabling quick
and easy deployment, monitoring, and troubleshooting from Cisco and
third-party applications.
Organizations rely on Cisco, third-party, and in-house developed network
management applications to achieve their OpEx and productivity goals.
Underpinning those applications are the embedded management features
available in every Integrated Services Router. The new Integrated
Services Routers continue a tradition of broad and deep manageability
features such as IP service-level agreement (IP SLA), Cisco IOS Embedded
Event Manager (EEM), and NetFlow which allow you to know the status of
your network at all times. These features, along with Simple Network
Management Protocol (SNMP) and syslog, enable your organization’s
management applications. |
