Rules of operation and use of BIX


Last modified: by the ISzT General Meeting on 11 December 2018
 Effective as of 1st January 2019


  1. The overall purpose of the BIX (Budapest Internet Exchange) is to prevent the Hungarian and regional internet traffic between the different internet service providers from overloading the international connections of the internet service providers and to provide a platform for exchanging IP based traffic between different internet service providers.

  2. Terms
    1. BIX: is a network system distributed geographically, which consists of BIX service access points (BIX nodes) and data transmission connections connecting them. Users of the BIX - the BIX members - can connect their own networks at the BIX service access points.
    2. BIX member: an internet service provider connected to the BIX with its own network via a BIX service access point (using the proper device or data transmission connection). A BIX member can only be an internet service provider that fulfils the requirements defined in Section 3 and accepts and adheres to the rules of the operation and use of the BIX defined hereunder. Regarding the connection to the BIX, BIX members may at their own discretion select their BIX service access points.
    3. BIX operator: BIX is operated by Internet Szolgáltatók Tanácsa (full name: Magyarországi Internet Szolgáltatók Tanácsa - Council of Hungarian Internet Service Providers, address: 1132 Budapest, Victor Hugo u. 18-22.), hereinafter: IszT. BIX  operator qualifies as an electronic telecommunication service provider duly registered in the public records of the National Media and Communications Authority under Act C of 2003 on electronic communication (hereinafter: Eht.).
    4. BIX Committee: a body within the framework of IszT, which sets the rules of using the BIX and supervises its operation. Members of the BIX Committee are those ISzT members who are also BIX members at the same time. Each member of the BIX Committee has one vote. The chairman of the BIX Committee is elected by the General Assembly of ISzT every year. It is the duty of the chairman to coordinate the activities of the BIX Committee, to convene Committee meetings and to administer membership application procedures. All BIX members are entitled to join the open meetings of the BIX Committee.
    5. BIX service: Service provided by the BIX service provider to the BIX members connecting the network of the BIX members to the BIX internet exchange. Conditions of the BIX service not regulated in this document are subject to the separate BIX service agreement between the BIX service provider and the BIX member.
    6. BIX basic fee services: Optical breakout service (according to 4 / f) furthermore 1 x endpoint of optical patchchord of maximum 12 strands (as per Point 2/e)       in the BIX Optical distribution cabinet
    7. BIX service basic fee: the annual lump-sum flat fee payable by the BIX contracting party during the term of the contract, which enables the use of the basic services
    8. BIX service fee: the amount due for any additional service beyond the BIX basic fee service.
  3. Eligibility requirements concerning BIX membership
    1. Any service provider is entitled to BIX membership if:

- Service providers conforming to these requirements are eligible for a simplified membership application procedure. The requirements must be met continuously. Eligibility is checked at half year intervals and membership can be cancelled in case of not conforming to the requirements.


  1. Furthermore, a provider is eligible for BIX membership if the application - justified by special reasons - is approved by the BIX Committee during the General Assembly of ISzT by a majority vote. The decision of the special judgment details the duration and the conditions of the special membership.

  7. Wavelength service: Optical wavelength service set up between two BIX nodes. Provision of passive wavelength along a non-protected optical pathway according to ITU C-Band 100 GHz. The required DWDM optical (1G or 10G) modules are provided by the BIX member.
  8. Dual Wavelength service: Optical wavelength service set upt between two BIX nodes. Provision of passive wavelength along two non-protected optical pathways according to ITU C-Band 100 GHz. The required DWDM optical (1G or 10G) modules are provided by the BIX member.
  9. Co-Location service: Network device(s) owned by a BIX member; hosted by BIX provider on a BIX node.

BIX members can connect to BIX using the interfaces of BIX Ethernet switch(es) located at BIX service access points. The optical transceiver (corresponding to the selected connection type) at the BIX switch is part of the BIX service. The BIX member is obliged - at its own expense - to ensure that its connecting interface is compatible with the selected connection type.
    6. Members have to use single mode optical distribution frame (ODF) connection to the BIX service access points, other optical connection and copper cable connections are not allowed.
