Diameter

Diameter protocol uses port 3868

Diameter protocol signaling load is increasing due to subscriber growth. Operators need to prove their networks can scale reliably and have the necessary capacity and built-in redundancy.Network equipment manufacturers (NEMs) need to test at all stages of the product life-cycle and conduct acceptance testing at the operator.The Valid8 Diameter Load Tester provides testing capabilities across numerous Diameter interfaces in fixed and mobile networks such as Cx, Dx, Ga, Gd, Gx, Gy, Nasreq, Rf, Rx, S6a, S6c, S6d, S6m, S6n, S6t, S13, Sd, Sh, Swx, T6ai, T6bi, Tsp, Zh.

There is a base protocol and are a number of applications within Diameter. Each specification defines certain messages and AVPs. Some of those applications include:
