This paper describes the performance of various methods of QoS assurance for each connection in an environment composed of virtual networks and dedicate end-to-end connections inside them. The authors worked on the basis of research conducted with the use of the authorial network management system named Executed Management, which uses resources virtualization platforms VMware and Mininet for testing purposes. We briefly describe our system and techniques we used and some alternatives we tested and discarded because of their limitations. Functionality and performance of proposed solution to widespread implemented mechanisms as OpenFlow and MPLS are compared. Reasons for selecting well-known techniques to isolate networks and limit bandwidth on different levels of virtualization are considered. The purpose of this paper is to show out our studies and performance we achieved.

W pracy przedstawiono wyniki analizy i badań symulacyjnych bezpieczeństwa protokołu IPsec. Zostały one poświęcone algorytmowi AES/Rijndael i ustaleniu, czy spełnia on ścisłe kryterium lawinowości Webstera-Tavaresa [13]. Uzyskane wyniki pozwoliły na ocenę bezpieczeństwa algorytmu AES/Rijndael, z punktu widzenia jego odporności na kryptoanalizę różnicową oraz protokołu IPsec.

In the paper results of security analysis of VPN networks based on IPsec protocol with implemented AES/Rijndael cipher are presented. Particularly, the AES/Rijndael algorithm and the fulfillment by the cipher of a SAC criterion proposed by A.F. Webster and S.E. Tavares in [131 is discussed. The results of the research enabled to assess the security of the AES/Rijndael cipher in VPN networks based on IPsec protocol.

Digital information, fiberoptics, and telecommunications satellites are making it possible to implement the concept of the global village. The sector is responding to this opportunity in virtual laboratories, virtual product development teams, and virtual factories where individuals and facilities which are remotely located are linked for the common good as well as the task at hand even allowing a continual effort to be on a project as the work day moves around the globe. Eventually this situation will also be recognised by the academic community and knowledge will be transferred between libraries, and students instantly between locations on the globe. Through the Internet such possibilities are now being initiated. However, it will be the long term commitment of the private sector to the concepts of telecommuting, remote distance and digital libraries which will ensure its The termination of the Cold War has conditions allowing the implementation of concepts. Economic conditions currently within the United States are quite robust to an acute shortage of qualified experts. In and Central Europe employment levels are not as high while in the Republics of the Former Union large numbers of trained experts are employment. Consideration may also be to other areas of the globe such as the Pacific Rim, Africa, and South America. Through the of computer/telecommunication in regions lacking local infrastructure it is to link individual talent with scientific, engineering, and technical needs worldwide as well as to provide the opportunity for the acquisition of marketable and desired skills and training. In Summer 1999 prototype Viewnet centers will be established in St. Petersburg, Moscow. Yerevan, Kiev, and Dnepropetrovsk which will be linked through evolving lntemet2 systems to participating locations within the United States allowing the rapid transfer of very large files as well as the transmission of the highest quality audio and video. Such multinational connectivity should in the future provide considerable political and economic stability for the world.
