What's is an SLA?

When a communication service provider (CSP) offers to sell an Ethernet service (e.g. E-Line or E-LAN), they usually include a Service Level Agreement (SLA) for the service. The SLA is a contract spelling out the agreed upon performance metrics used to measure what the end customer's service experience will be. 


Scaling NFV Services - The Role of Federation

Dec 8, 2014 by Ramesh Nagarajan

Ramesh NagarajanOperators around the world have embraced NFV as a transformative initiative and are actively pursuing proofs-of-concept and trials to prove the technology. As we move towards field deployments, it is important to consider the needs for scaling NFV deployments and to bake the requirements into the architecture and technology.

Service Management in the Brave, New, and Virtualized World

Aug 15, 2014 by Ramesh Nagarajan

Ramesh NagarajanThese are exciting times in the world of Network Functions Virtualization (NFV). NFV fever has truly gripped the market and NFV-washing is fully underway. However, there is real progress underneath and beyond the hype.  Operators are beginning to seriously contemplate commercial deployments of NFV, and are devoting considerable effort to the important topic of NFV service management. Network operations teams at the service providers have been asking the difficult questions of how to manage all of the virtual stuff compared to the physical, custom built appliances they have operated in the past.

SDN, NFV and Future Innovation

Sep 25, 2013 by Prayson Pate

There have been many benefits proposed for using Software Defined Networking (SDN) and Network Functions Virtualization (NFV) to modernize the datacenter and network.  Many of these benefits are fairly near term and quantifiable.  However, the biggest value for SDN and NFV is in the enablement of future innovation and services.





Services, Services, Services

In previous blog entries I have talked about applying cloud and NFV (Network Function Virtualization) principles to the edge of the network.  In this entry I will talk about why these principles are important and how they can benefit the service provider.  These benefits fall into three categories related to services:

  • Service creation – The process of defining, implementing, and marketing new services
  • Service activation – The enabling of a service instance when ordered by a customer
  • Service assurance – The measurement and reporting of compliance with the Service Level Agreement (SLA).
