Challenge

Performance benchmark within a multi-vendor network

The Airtel Africa Group is confronted with the challenge of providing consistent high Quality of Service across all of 15 networks. Managing a multi-vendor, multi-technology and constantly evolving network is extremely complex. Counters, coming from 5 different types of network equipment, are system-focused, rarely defined on the same rules and do not fully translate end-user experience.

Visibility on SLAs for overall managed service contracts

Before partnering with Astellia, it was particularly challenging for the Airtel Africa Group to benchmark performance across equipment based on reliable metrics and monitor SLAs with their telecom equipment manufacturers in a trustworthy way.

Airtel Africa requirements:

  • Reliable and comprehensive performance visibility over the various networks from Airtel HQs
     
  • Equipment vendor performance benchmark
     
  • Performance management solution with drill down investigation capabilities
 

Solution

Vendor-independent reporting & user-centric investigation

Correlating data coming from multi-vendor OSS and from Astellia’s non-intrusive probes, the solution generates actionable performance indicators and dashboards allowing operators to measure equipment efficiency (nodes, RNCs, GGSN, SGSN) and optimize end-to-end network performance

The solution was deployed on 2 levels:

  • At HQ level in Nairobi, the solution is used by Airtel CxOs and Corporate Network managers responsible for optimizing network investments, revenues and analyzing individual network profitability.
  • At operation level, the solution is deployed countrywide and enables Optimization and Performance teams and local CTOs to monitor their individual network and drill down any issue responsible for network inefficiency and poor quality delivery down to cell level.

 

Benefits

  • Vendor-independent view of the network
     
  • Reliable SLA assessment
     
  • Informed decisions based on reliable business intelligence
     
  • Maintainance of tight CAPEX and OPEX controls
