Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional high-level programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang ...
This can be used to determine the probability of packet loss or delay, according to various assumptions made about whether blocked calls are aborted (Erlang B formula) or queued until served (Erlang C formula). The Erlang-B and C formulae are still in everyday use for traffic modeling for applications such as the design of call centers.
Extended Erlang B differs from the classic Erlang-B assumptions by allowing for a proportion of blocked callers to try again, causing an increase in offered traffic from the initial baseline level. It is an iterative calculation rather than a formula and adds an extra parameter, the recall factor R f {\displaystyle R_{\text{f}}} , which defines ...
OTP is a collection of useful middleware, libraries, and tools written in the Erlang programming language.It is an integral part of the open-source distribution of Erlang. . The name OTP was originally an acronym for Open Telecom Platform, which was a branding attempt before Ericsson released Erlang/OTP as open sou
The Erlang distribution has two parameters, the shape an integer k > 0 and the rate λ > 0. This is sometimes denoted E ( k ,λ). The Erlang distribution can be written in the form of a phase-type distribution by making S a k × k matrix with diagonal elements -λ and super-diagonal elements λ, with the probability of starting in state 1 equal ...
Elixir is a functional, concurrent, high-level general-purpose programming language that runs on the BEAM virtual machine, which is also used to implement the Erlang programming language. [3] Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications.

Erlang Shen, or simply Erlang, is a god in Chinese folk religion and Daoism, associated with water (flood control), justice, warriorhood, hunting, and demon subdual. He is commonly depicted as a young man with a third, truth-seeing eye in the middle of his forehead, wielding a three-pronged spear, and being accompanied by his loyal hunting dog, Xiaotian Quan.
