Tango Telecom joins the policy server vendors publishing their performance numbers (see BroadHop and Bridgewater/Amdocs). I am not sure if one can compare product performance based on these statements, but transparency and visibility, as we know, are important qualities.
Tango announced ".. the completion of a record breaking Policy performance benchmark on the latest generation of COTS blade servers using Xeon 6 core CPUs .. The Tango iAX™ Data Policy Server achieved sustained performance of over 12,000 PDP contexts established per second per blade, at 70% CPU utilisation. The platform also demonstrated unprecedented scalability, to over 192K contexts/second from a single blade server chassis".
Kieran Kelly, CTO of Tango Telecom, commented: “.. The next wave of policy solutions, as well as offering sophisticated features such as load aware policy and dynamic pricing, must be able to scale way beyond what is currently possible. To put this exceptional benchmark in context, just a single fully equipped blade server, with the Tango iAX™ Data Policy Server, could establish data sessions for over 11M data subscribers in a single minute”.
