These KPIs are a requirement of the ADSL regulations which were published on 17 August 2006 by the Independent Communications Authority of South Africa (ICASA).
The regulations require Telkom and Internet Service Providers (ISPs) to publish, on a quarterly basis, Key Performance Indicators (KPI) detailing at the least, packet loss, average latency and jitter for the provisioned ADSL service.
The MWEB and Telkom Key Performance Indicators (KPI) give some insight into the performance of Telkom and MWEB’s ADSL networks, but the lack of proper testing guidelines by ICASA is a significant shortcoming in the value of these reports.
Despite the shortcomings – which were essentially brought about by a very poor set of regulations by ICASA – it remains interesting to look at the KPIs published by Telkom and now MWEB.
The following table provides a comparison on the performance of MWEB and Telkom’s ADSL networks.
