What is a “Controller”? And how many do we need?

June 26, 2013 at 6:10 am PST

Thanks to SDN, the “Controller” word pops up in many network architecture discussions these days. In networking alone, we’re already surrounded by many “controllers” and we’re busy introducing more as we speak:  For example, Session Border Controllers or Wireless LAN Controllers have been around for quite some time, and have recently announced the OpenDaylight Controller, the Cisco XNC, or the Cloupia Unified Infrastructure Controller. So what is a “Controller” in networking terms, and how many do we need in emerging network architectures?

The onePK Software Architecture

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.

For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.

The main elements of the onePK software architecture are illustrated Read More »

Get Fast, Easy Actionable Information with Cisco Prime Performance Manager

Contributed by David Flesh, Sr Manager, Product Marketing, Cisco Network Management Technology Group

Cisco Prime Performance ManagerA common theme we hear from service providers is the challenge of delivering high-quality services at the lowest possible price. IP Next-Generation Network architectures are increasingly complex to operate with the volume of services growing at an exponential rate. To sustain the cost of deployment and maintain average revenue per user, communication service providers need an efficient management system that provides visibility into network and service performance.

Cisco just introduced a new performance management solution that helps enable service providers to proactively manage their next-generation networks, including service assurance and capacity planning. Cisco Prime™ Performance Manager complements an existing set of network management tools or works completely as a standalone solution. Cisco Active Network Abstraction (ANA) customers like the easy integration and the ability to access service and element performance information from the topology views.

Cisco Prime Performance Manager provides more than 200 pre-generated reports on a wide range of technologies. These reports help operators and network planners answer those questions that keep you up at night; questions such as which devices are over-utilized, what backhaul links are congested, and which services have poor quality or response time. With dashboard views showing network-level availability and utilization reports, operators can quickly identify the most pressing issues impacting the network. Pre-generated reports provide deep visibility into such areas as application traffic, availability of services and devices, IP quality of service, IP protocols, IP service level agreements, resource utilization, and transport statistics.
