You can use them straight away or design your own traffic workbooks with the eight built-in functions – there is a simple example on the Ville Tuulos talks about Disco, the Map/Reduce framework for Python and Erlang, real-world data mining with Python, the advantages of Erlang for distributed and fault tolerant software, and more. The erlang law is all about consumer QoS 🙂 if you have 35 channels, how much traffic can this sytem carry assuming that subscribers should not be rejected more than 2% of the attempts, and assuming (and that’s important) a random arrival of calls.
