Between now and the end of this decade, the evolution of software defined networks (SDN)/ network functions virtualization (NfV) will have become a full-fledged revolution. The IT industry is pushing for dynamic network services to:
To date the industry has been focused on the configuration management challenges that need to be addressed to ensure new services are delivered as required, when required-down to the individual subscriber. The difference going forward is that service assurance, which has historically been built on individual monitoring tools, has to be a fully synchronized, real time process. What is required is a new concept which AssureNowTM defines as Flow-through Service Assurance.
Flow-through Service Assurance enables a real time, integrated alignment with service chaining while also performing real time tracking and monitoring of network resources on a UNIFIED basis. Real time changes in this new dynamic environment need to be monitored end-to-end from static legacy networks to new virtualized networks and tracked on a per-application and per-subscriber level basis. When there is a need for more or less bandwidth to support a new service or maintain a service level, the monitoring platform needs to be able to provide that information on a pre-emptive basis. AssureNow has this capability and does so by leveraging its unified service assurance platform. As the picture below illustrates, service assurance is vital to the success of the new virtualized capabilities. AssureNow provides a unified approach to fault, performance, root cause, service level management and multi-tenancy to the interface level for physical and virtualized networks.
AssureNow is able to unify, simplify and automate management of hybrid clouds-from legacy to NfV using its unified platform. AssureNow provides the following as depicted below:
