Fragments of Yokohama

Early in November held next regular meeting of the community IETF (Internet Engineering Task Force) with the serial number 94. This time, experts from around the world gathered in Japan’s Yokohama. Previous IETF 93 meeting held in the summer in Prague.

IETF is an international community whose goal is the mutual compatibility of equipment and systems. The means to achieve this goal is the development of standards and specifications, which serve as a recommendation for developers. The idea is simple fact – if the program to operate according to the specification, should be able to seamlessly communicate with another. Currently, the IETF focuses primarily on security and privacy. Community activity is based on voluntary activity enthusiasts from around the world, but among the participants and a number of representatives from various companies who are trying to present their implementation. The community is made up of programmers who value functional code, so existing functional implementation gives one great advantage in negotiations. On the other hand, participating in meetings with top professionals, who are determined to spare no constructive criticism if they do not seem to draft something.

Actual meeting was preceded by the so-called hackathon events for groups of programmers who have the opportunity to come together and work together at one table to software development. Although I participated passively, I must say that the atmosphere here, there was a very creative and friendly during a hackathon, a number of interesting new tools. The main point of the program was to me the working group meeting MILE (Managed Incident Lightweight Exchange), under which I gave a presentation summarizing data representation incidents that we use here in the association. The aim was to establish communication with a wider group of people from miles and agree on further cooperation. Members of the group’s willingness to provide our experience and offer of cooperation warmly welcomed.

In the following days were held meetings on the subject configuration, ie. NETCONF technology and Yang, which is also intensely engaged. Thanks to the activities in this area is well known in the CESNET relatively large part of the IETF community, taking credit for it carries a particular colleague Radek Krejci and our former collaborator Ladislav Lhotka (now CZ.NIC). The theme was, among other performances emerging library libyang that according to preliminary results bring a large increase in performance and resource savings in existing open source tools that use the library libnetconf. The last day was devoted IETF94 action Bits-N-Bites, where various organizations had the opportunity to present their projects. Present were, for example, people from the Japanese domain registry, peering center in India, or companies Huawei and NEC.


IETF94 again significantly helped expand awareness of the community about cutting-edge research and development in the field of configuration of network elements and network hardware, which we here devote. One of the concrete results of the continuation of cooperation in the framework of the working group MILE representation of information on security incidents. The next meeting we would like to present our latest results in the processing and analysis of monitoring data in a distributed environment.
