VoIP Big Bang? 1,100 Providers and Counting
Rapid expansion of the Internet telephone universe means new challenges for ISPs
Waterloo, Ontario; April 27, 2005 – New research from broadband equipment maker Sandvine Incorporated shows that new voice over Internet protocol (VoIP) providers are coming online at an unprecedented rate – numbering more than 1,100 as of April 5th.
VoIP is in the midst of a major marketplace expansion as a myriad of players, from major brand telcos and cable companies to independent operators, ‘Mom & Pop’ local services and free Internet telephone application developers like Skype, all attempt to cash in on the craze.
The rapidly expanding VoIP universe poses serious challenges to the broadband service providers who carry VoIP traffic on their networks. Voice traffic has unique quality of experience (QoE) requirements that demand more rigorous and flexible traffic handling techniques.
“Broadband providers can enhance a user’s online experience by prioritizing or reserving bandwidth for latency-sensitive and interactive applications like VoIP,” said Dave Caputo, co-founder, president and CEO of Sandvine. “For service providers looking to roll out new VoIP services of their own, it is imperative that they understand how many minutes are already being consumed by their broadband subscribers.”
The battle for market share amongst all these offerings will be fought on the field of quality of experience (QoE), a measure of end-to-end performance that combines reliability, standard quality of service metrics and subjective end-user experiences. The failure or success of VoIP offerings depends on the level of QoE that a service provider can achieve and sustain, so network managers must determine very quickly how QoE can best be quantified and ensured.
Sandvine arrived at its VoIP figure after analysing data traffic moving across its global network of ISP customer sites, which account for more than 20 million broadband subscribers worldwide.
