ISPA Internet Exchanges: 8Gbps and counting

Internet Service Providers (ISPs) peering at the Internet Service Providers’ Association’s (ISPA’s) Johannesburg and Cape Town Internet Exchanges (INX) are sharing over 8Gbps of traffic at peak times. This is according to the latest ISPA INX traffic stats.

ISPA’s INX traffic stats show that the ISPs share around 6.5Gbps of traffic at the Johannesburg Internet Exchange (JINX) during peak times.

The latest Cape Town Internet Exchange (CINX) stats show that service providers share 2Gbps of traffic at this exchange.

Graham Beneke, network engineer at Neology and chairman of ISPA’s INX working group, said that the strong growth comes on the back of increased bandwidth use in South Africa along with a steady increase in the number of international CDNs deploying nodes into South Africa.

Beneke said that broadband connections are getting faster, and that users are consuming more bandwidth with the wider adoption of uncapped broadband services.

The Durban Internet Exchange (DINX), which was launched in September 2012, shows peak traffic sharing of between 10Mbps and 20Mbps.

This is only a fraction of the traffic shared at the Johannesburg and Cape Town exchanges.

While DINX remains small, Beneke said that they have seen a tenfold increase in traffic over the last few months.

The main reason for the low traffic volume at DINX, Beneke explained, is the absence of the big ISPs at the exchange. Many have not yet deployed core points of presence in the Durban area and peer their traffic at JINX or CINX instead.
