3 Aspects Necessary for Detectability & Configurability of Highly Resilient 5G Infrastructure
Service Assurance (SA) and telemetry are increasingly relevant in 5G networks and Edge deployment as network architectures evolve to become more distributed. 5G and Edge networks introduces dynamic network architectures that require a level of closed loop automation and contextual service assurance for meeting Service Level Agreements (SLAs) establishing itself as a foundational pillar in the network transformation. Intelligence with Machine Learning algorithms & self-learning networks with artificial intelligence require a set of open standard telemetry interfaces from various layers of European Telecom Standards Institute (ETSI) Network Function Virtualization (NFV) model. Example of what Six Nines (99.999%) Reliability looks like is shared here.
A resilient cloud requires resilient platform technologies which include Resilient CPU, Resilient Memory, and Resilient Storage technologies combined with the ability to make the rich set of platform telemetry available using Open Industry Standard interfaces to multiple analytics methods including classical analytics methods and Machine Learning. Self-managed and highly automated data centers require understanding of fault detection, correction & avoidance across multiple layers of the stack to build resilient cloud. To achieve a level of real time or near real time based closed loop automation, the NFV deployments and Software Defined Networking (SDN) environments require rich set of telemetry data sets and endpoint definitions with clearly defined KPIs. True automation in fault management and platform resiliency to achieve self-healing across the infrastructure at scale could be only achieved by taking in to consideration right amount of data from customized set of metrics relevant to the subsystem under review with an appropriate collection interval that can be processed for relevant corrective action.
Service assurance, in general, encompasses FCAPS components — Fault, Configuration, Accounting, Performance and security. In order to provide five nines availability, the orchestration and service assurance implementation require to identify faults and service failures in the…
