BLOG: Why ISPs are triple winners

ISPs are triple winners as IXP networks cut costs and latency while increasing bandwidth

Flexible connectivity

Flexible connectivity options on the switches provide support for 40 GbE, 10 GbE and 1 GbE port speeds, with optical transceivers and cables that enable support for various distances.

Low latency is critical to high-speed traffic transmission through IXP networks, so switches capable of 2.3μs1 latency are ideal for IXPs, in conjunction with switches that can provide 800ns latency in the access layer.

ISPs rely on IXPs to provide better performance, higher availability and lower cost of services to ISP subscribers. IXPs need to adhere to pre-defined SLAs while providing these services by maintaining highly available networks with minimal disruptions. Service monitoring and performance verification in real time with extensive simple network management protocol (SNMP) and SFLOW support helps IXPs maintain high availability while managing and monitoring network switches.

The technology proved to be a game-changer for LINX and its member companies that include media, content providers and hosting providers - 450 members across 55 nations using 10 data centres.  They all needed to accommodate a huge usage surge during the Olympics.

Using IXP, LINX seamlessly upgraded its Internet exchange service without any disruption or degradation.  A saving of 15 per cent in operating expenses from using world-class switches was passed on to LINX membership.  LINX future-proofed its infrastructure in terms of cost/performance, scalability and flexibility.

Olympics visitors were winners when they experienced little to no slow-down or additional latency during the event. Analysis showed that LINX's infrastructure handled the traffic surge smoothly with seamless connectivity and better than 99.999 per cent availability.  Today ISPs worldwide are experiencing similar results.
