New version of Erlang Open Telecom Platform framework released
27 September 2017   1422

New update for telecom related Erlang framework available now.

What's new?

This updates contains bug fixes and small improvements in general. Let's check the most interesting updates.

  • diameter:

    • Add service option decode_format to allow incoming messages to be decoded into maps
      instead of records.
    • Decode performance has been improved.
    • Add service/transport option avp_dictionaries to give better support for dictionaries only defining AVPs.
  • erts: Upgraded the ERTS internal PCRE library from version 8.40 to version 8.41.

  • erts, kernel, tools: Profiling with lock counting can now be fully toggled at runtime in
    the lock counting emulator (-emu_type lcnt). Everything
    is enabled by default to match the old behavior, but
    specific categories can be toggled at will with minimal
    runtime overhead when disabled
    lcnt:collect and lcnt:clear will no longer block all
    other threads in the runtime system. This makes it possible to run the lock counting
    under heavier load.

  • erts: The zlib module has been refactored and all its operations will now yield appropriately,
    allowing them to be used freely in concurrent applications.

What is Erlang\OTP?

Open Telecom Platform(aka OTP, Erlang / OTP) is a software framework that contains a set of libraries and design patterns for building scalable distributed applications in the Erlang programming language.

The framework was created by Ericsson as a part of the of AXD series ATM-routers projects and released in 1996, embodying many years of experience in creating fault-tolerant systems.

High reliability of applications is possible due to a simple, but powerful mechanism for handling exceptions, on the basis of which general libraries were built. Using libraries of the OTP framework, the Erlang developer programs the required behavior, and libraries deal with the handling of exceptions. This approach makes the code shorter and usually introduces fewer errors.

Topic: "WebPerformance - Why and How?"

Stefan Wintermeyer,
Stefan Wintermeyer

A dive into the topic of fast webpages. Why does a specific webpage load fast or not? Why is it important? What's the difference between a mobile user on a 3G network and one on a fiber connection? What can be done on the server? Is JavaScript the solution or the reason for this problem?
