Conclusion
The use of VPN technologies within the Janet community has been considered and the requirements for centralised provider-provisioned VPN services have been assessed. The assessment was carried out in March-April 2006, when the VPN survey was conducted. 121 of the responses received showed strong interest in VPN services within the Janet community: over 80% of respondents indicated that they use some form of VPN service; about 55% of the rest plan to use VPN in the near future. However, the respondents’ answers also indicated that the community has no strong demand for centrally managed VPN services. Taking into account this result of the survey, centrally managed VPN services will not be deployed across Janet in the foreseeable future. However, if demands for such services arise within the Janet community then this area may be explored further.
