Architecture

SEN - Slovenian Education Network is built on top of ARNES (Academic and Research Network of Slovenia).

SEN consists of three levels:
Upper Level - Ring of Entry Servers: consists of a small number of entry servers that have knowledge about the structure of the Network and direct the user to the proper server/material. All entry servers are equivalent - they provide the same information about the Network. This ensures the robustness against failure of an individual server and the distribution of workload.
Lower Level - Information Providers: consists of ordinary servers that actually provide the information. For some time some information providers will be hosted at other organization's servers. Intronet.
User Level - consists of users/schools with the Internet access.
