This whitepaper explores the new 5G core architecture and how it solves the present-day problems of a closed framework through its programmability and service agility. It also delves into some of the use cases to see how other industry verticals are benefited by this new architecture thus creating new business models for the Service Providers. … Continue reading 5G: Core Architecture

In the SDN primer blog post, we touched upon the basic building blocks of SDN. In this post we will try to outline how an ideal controller should look like taking a high level look at the SDN controller architecture. Please note that this is just a high level schema and a lot can be … Continue reading SDN Controller Architecture
Software Defined Networking or SDN is defined as the physical separation between network control plane and user plane. This architecture decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. The basic building blocks of a SDN based … Continue reading Software Defined Networking (SDN) – A primer
A VNF manager manages the state, lifecycle and resources of one or more VNFs. It is responsible for instantiation, update, query, scaling,healing, termination etc of the VNFs. (Read about NFV Architecture here) VNF Descriptor ( VNFD) The deployment and operational behaviour of each VNF is stored in a VNF Descriptor file ( VNFD). It contains … Continue reading VNF Manager (VNFM)
The NFV Orchestrator or NFVO has two primary responsibilities, resource and network service orchestration. (Read about NFV Architecture here) 1. Resource Orchestration: Resource Orchestration refers to the management of virtualised and non-virtualised resources in the Network Functions Virtualisation Infrastructure (NFVI). It will basically oversee the allocation of resources and monitor the allocated resources … Continue reading NFV Orchestrator ( NFVO)
NFVI - Network Functions Virtualisation Infrastructure NFVI Consists of all resources required to gain virtualisation. NFVI can span across many locations, e.g. a part of the infrastructure could be in city A and another at city B to enable geo-redundancy. A location where NFVI node is deployed is called NFVI-PoP ( NFVI Point of … Continue reading NFV Architecture
