" .. The Diameter Traffic Calculator uses eight variables such as the number of LTE devices, and their projected yearly growth, number of simultaneous applications and expected dormancy of applications to estimate the diameter traffic in a specific network. It also factors in the percentage of postpaid subscribers and projected VoLTE users. The results are extrapolated over a 5 years period based on specified growth rates. In addition to reporting total Diameter messages per year, the tool also projects Diameter messages by network element: HSS, PCRF and OCS".
