I searched for an optical fiber communications report today. Well, of course, found, and to the reference was attached a list of recommended literature on this topic (i.e. on the topic of networks), which surprised me very much =). Here is the list:

1st Methods and means of protection of information in computer systems.Horev 2005
2nd Basics of Radio Electronics and Communications.Nefedov 2005
Three The Russian people. Book 1: Celebrations, Rites and Traditions, 2004
4 is Computer Networks: Instructional Guide on Administration of Local and Unified Networks (2005)

Apparently, the network administrators set up this is a very old Russian rite, with the drumming of the drum, the brewing of a special ceremonial beer and everything else, and if the server does work, then there will be a real Russian holiday =)
