Our Network Evaluation Approach

As data services are growing exponentially in a competitive environment, this is creating price pressure that is leading to significant price compression. At the same time, voice revenues are still dominant and data services are consuming the vast majority of bandwidth capacity where the underlying network infrastructure is undergoing transformation to packet-based technologies of IP/MPLS and Ethernet. This is creating a situation where operators need to carefully manage and reduce the total cost of operating the network whilst at the same time meet customer expectations for increased performance, quality and reliability.
Making the situation more challenging to manage is the typical way in which packet-based technologies have evolved within most operators.  These challenges include the setup of islands of disparate infrastructure that have been built for different requirements. These islands have tended to be quite small and have been deployed in a fashion that suits the short term, minimized cost to the supplier rather than the long term, total cost of ownership to the operator. The pressures of these rapidly evolving customer services are creating a challenging situation where disparate environments are required to interwork with each other and the global Internet. This interaction usually starts in an informal, ad hoc fashion and rapidly becomes difficult and costly to manage, operate, scale and troubleshoot.
The diagram above shows our approach to simultaneously reducing cost, whilst improving reliability, quality and performance.
Core2Africa’s philosophy to taking on the challenge of reducing the total cost of ownership whilst improving network performance and reliability is to evolve the environment into a structured and modular, converged services environment with well-defined roles and responsibilities of the various network components. In order to achieve this, the following are the major activities that take place, namely:
  • Convergence: This is the process of consolidating multiple disparate, packet-based environments into a single seamless network infrastructure
  • Consolidation: This is the process of eliminating duplicate components in the network in order to improve the total cost of ownership and reliability and reduce the complexity of management
  • Simplification: This is the process of streamlining the underlying network complexity and eliminating complex, inefficient interfaces and configurations. Key to this is to develop standardized and structured methods of deploying services
  • Automation: This entails the use of systems to perform common, repetitive and tedious tasks that are often prone to human error
The diagram below displays what Core2Africa believes are the key factors that need to be addressed in order to optimise the underlying IP/MPLS and Ethernet Infrastructures.
Key to the evolution of converged services networks is the separation required between the ever increasing range of diverse services and the underlying network infrastructure. In order to build a sustainable environment it is vital to take a structured and modular approach considering the end-to-end requirements and network infrastructure. The diagram below displays the approach that has been adopted by Core2Africa.
