NIX.CZ – Neutral Internet eXchange for the Czech Republic and Beyond!

NIX.CZ, z.s.p.o. (Professional Association of Legal Entities) is a company, which associates Czech, and foreign Internet related businesses in order to mutually interconnect their networks. Access to the company’s infrastructure is enabled through seven collocations in Prague.

Currently, NIX.CZ is the largest Neutral IXP (Internet Exchange Point) in the Czech Republic. Consistent and meticulous planning, sophisticated technical solutions and a 24/7/365 technical support have led to a failure-free operation of the node. The association has encouraged and facilitated IPv6 protocol- based peering since 2003.

NIX.CZ is a dynamic company, which actively participates in the development of the Internet. Through our General Meetings and Social Events we enable our members and customers to meet, not as competitors but as allies, cooperating on the future of the association.

The NIX.CZ association also organizes free lectures on current topics for its members.

FENIX

The FENIX project was created by the Czech peering node NIX.CZ and is primarily a reaction to intense DoS attacks targeting Czech internet services, media, banks and operators in March 2013. The purpose of the project is to ensure the availability of Internet services of the connected entities during a DoS attacks.

A participation in the project is subject to a number of conditions set in the Terms which must be fulfilled by each company wishing to join the project. By joining the FENIX project, the participating organizations have clearly showed their interest in increasing network security and improving their customers’ safety.

The FENIX project is managed by its members themselves. The latter are independent of the NIX.CZ association and have complete decision-making autonomy.

A short clip on how Internet exchange nodes work

This short video sheds light on the mysteries of how the Internet works and explains the key roles of Internet exchange nodes. Through peering, that is through linking of autonomous systems, the Internet develops. This video was made in a cooperation with EURO-IX and its goal is to present the key role of the Internet exchanges such as NIX.CZ.

Topology

Topology NIX

In 2010, the topology of NIX.CZ Internet Exchange migrated from a “ring” topology to a virtualized “dual star”. This change provides greater stability to the whole peering platform and has also simplified further development. NIX.CZ took advantage of this in 2011, by migrating from the Cisco Catalyst 6509E access switch to the Cisco Nexus 7010 model. The change in the topology made it possible to carry out this transfer while only affecting one company at a time (i.e., the one being transferred). The change technology also allowed for continued growth in the volume of transmitted data, as it was expected in the following years. At the same time, the new topology allowed the Association to open the new connection point NIX5, more than 8 years after the opening of the previous one. Because of a high demand for 100GE connections after 2014, NIX.CZ began to implement the Cisco Nexus 7710 access switches. In 2016, NIX.CZ also began running so-called passive points, which have no active technology but make it possible to connect to NIX.CZ using dark fibres.

In mid 2019, NIX.CZ interconnected its nodes in Prague and Bratislava, enabling easy networking between the Czech Republic and Slovakia. This connection is realized by two independent 100GE circuits that are topologically separated.
