Remote laboratory for computer networks

Abstract

The article introduces the reasons for realisation of the remote laboratory of computer networks which originate from the comparisons of the alternatives of working with the specialised networking hardware. These use the principle of virtualisation or simulation of such devices as an alternative for obtaining competencies from the area of computer networks. Due to this reason, this article discusses other technical solutions and the analysis of usability of such solutions is conducted. For a maximal efficiency of the networking hardware utilization in laboratories it is necessary to make it fully available for students which is the 24/7 regime. This option can be executed using secure technologies and protocols for distant accessing of laboratory hardware. This solution, which is based on using console controllers and single utility interface, is introduced and described in detail in the following paragraphs. Moreover, from the analysis of the pilot operation of remote access to the laboratory equipment of the networking laboratory, suggestions for improvement of the current solution and its usage in fully working condition - access to a greater number of students in unlimited regime - can be obtained.
