Bulgarian Research and Education Network association


Acceptable Use Policy (AUP)


The “Bulgarian Research and Education Network” (BREN) association can not accept any liability for any loss or damage resulting from the use of the material contained herein. The information is believed to be correct but no liability can be accepted for any inaccuracies.

1. Preamble

BREN aims to create, promote, offer, participate in and preserve the requisite bases for effective use of modern computerized telecommunication technologies in the education, culture and research in Bulgaria.

The present document collects and summarizes all rules for the access to BREN’s network.

2. Background and Definitions

2.1 National Research and Education Network (NREN) is the name given to the collection of all networking services and facilities, which support the communication and information requirements of the education and research community in Bulgaria.

2.2 The BREN association is responsible for the development of the NREN. Any dispute over the interpretation of this Policy will be resolved by BREN’s General Assembly.

2.3 This Policy applies directly to any organization (a “User Organization”) which is authorized to use the NREN and has signed an appropriate contract with BREN’s Chairman. The User Organizations will be responsible to ensure that the members of their own user communities use the NREN services in an acceptable manner and in accordance with the current legislation.

2.4 It is therefore recommended that each User Organization establishes its own Acceptable Use Policy (AUP) within the context of the services it provides to its users, and in a form that is compatible with the conditions expressed in this Policy. The User Organization’s AUP may refer to, or include, this document. If only parts of this document are included, this must be done in such a way as to ensure that there is no misrepresentation of the intent of this Policy. BREN can provide, if necessary, advice on the formulation of an Acceptable Use Policy.

2.5 Commercial traffic is Internet traffic between organizations that are neither research, nor educational in nature.

2.6 Commodity traffic is Internet traffic between a research or education institutions and a non-research or education organization.

2.7 Research traffic is Internet traffic between research or education organizations.

2.8 High Performance Research traffic is traffic between a small subset of research and education institutions that requires high performance networks and services such as Quality of Service (QoS) for effective delivery.

3. Acceptable Use

3.1 In order for use to be acceptable, it must be compatible with the aims of BREN and observe the rules set forth in this AUP. The decision in this regard shall be made by the General Assembly of BREN, according to recommendations of a Board of Experts.

3.2 A User Organization may use NREN services for the purposes of information exchange and scientific research with other User Organizations, and with organizations interconnected to networks, which are made accessible based on agreements signed by BREN’s Chairman.

3.3 The NREN accepts research traffic, high performance research traffic and commodity traffic. Commercial traffic is not allowed, except in cases of demonstration service limited in time (no more than one week monthly).

4. Unacceptable Use

4.1 The NREN may not be used for any of the following:

4.1.1 The creation or transmission (other than for properly supervised and lawful research purposes) of any offensive or pornographic images, data or other material, or any information, images, data or other material, which are inadmissible according to the Bulgarian legislation and conforming to the definition of cyber-crime.

4.1.2 The creation or transmission of material which is designed or likely to cause annoyance, inconvenience or needless anxiety for the users.

4.1.3 The creation or transmission of material containing information, which could be classified as offensive or defamatory.

4.1.4 The transmission of materials that infringes the Copyright Law.

4.1.5 The transmission of unsolicited commercial or advertising materials either to other User Organizations, or to organizations connected to other networks.

4.1.6 Deliberate unauthorized access to facilities or services accessible via the NREN.

4.1.7. Deliberate activities with any of the following characteristics: Wasting of staff effort or networking resources, including processing time on end systems accessible via the NREN and the effort of staff involved in the support of those systems. Corrupting or destroying other users’ data. Violating the privacy of other users. Disrupting the work of other users. Using the NREN in a way that denies service to other users (for example, deliberate or reckless overloading of access links or of switching equipment). Continuing to use an item of networking software or hardware after NREN’s system administrators have requested that use to be ceased because it was causing disruption to the correct functioning of the NREN. Other misuse of NREN or networked resources, such as the introduction of “viruses”.

4.2 Whenever the NREN is being used to access another network, any abuse of the acceptable use policy of that network will be considered as unacceptable use of the NREN.

5. Granting of NRN Service

5.1 Access to the NREN for third parties is granted only after the prior agreement of BREN’s Chairman, with the exceptions of the cases stipulated in 5.1.1.

5.1.1 It is acceptable for a User Organization connected to the NREN to extend access to third parties on a limited basis, provided no charge is made for such access. For example, it is acceptable that a visitor to the User Organization be permitted to gain access to the NREN for the purpose of maintaining contact with his or her home organization. It is intended that such use be regulated by the User Organization in the same manner as it would regulate occasional use by third parties of its other facilities, such as its telephone and IT support systems.

5.2 Third party means a person or a legal entity which are not members of the User Organization.

6. Compliance

6.1 It is the responsibility of the User Organization to take all reasonable steps to ensure compliance with the conditions set out in this Policy document, and to ensure that unacceptable use of the NREN does not occur. The discharge of this responsibility must include informing those at the Organization with access to the NREN of their obligations in this respect.

6.2. Where necessary, service may be withdrawn from the User Organization. This may take one of the following two forms:

6.2.1 Infinite withdrawal of service, should the violation of these conditions persists after appropriate warnings have been given by BREN’s Chairman. The renewal of services would be made only when BREN’s Chairman receives proofs that the appropriate steps had been taken by the User Organization to ensure acceptable behavior in future.

6.2.2 Suspension of service, should a violation of these conditions causes serious degradation of the service to other users of the NREN. Such a suspension may be made on the judgment of NREN’s system administrators, and service would be restored when the cause of the degradation of service to others had been removed.

6.3 Where violation of these conditions is illegal or unlawful, or results in loss or damage for BREN or the resources of third parties accessible via the NREN, the matter may be referred for legal action by BREN, according to the Bulgarian legislation, for adjudging of damages.

6.4 It is preferable misuse to be prevented by a combination of responsible attitudes to the use of NREN resources on the part of users and appropriate disciplinary measures taken by their Organizations.

7. Closing remarks

7.1 This AUP is to be regularly reviewed (if possible, annually) and to be updated in accordance with any eventual changes in the circumstances.

7.2 The amended text of the AUP is to be approved each time by BREN’s General Assembly.
