Preemption is a traffic engineering technique in Multiprotocol Switching Network that enables creation of high priority paths when there is not enough free bandwidth left on the route. Challenging part of any preemption method is to select the best set of paths for removal. Several heuristic methods are available but no wider comparison had been published before. In this paper, we discusses the dilemmas...
Growing expectations for a fast access to information create strong demands for a universal telecommunication network architecture, which provides various services with strictly determined quality. Currently it is assumed that these requirements will be satisfied by Next Generation Network (NGN), which consists of two stratums and includes IP Multimedia Subsystem (IMS) elements. To guarantee Quality...
MPLS architecture for transport networks play the significant role in the development of next generation networks, in particular with regard to the guarantee of continuity of communications "end-to-end" through a variety of heterogeneous segments of the telecommunications network. The article presents the concept of Mobile MPLS-TP with the use of OAM channels to support the mobility of users...
This research began when observations were made on any-to-any-connection services that require QoS (Quality of Service) and tunnel measurements. Tunnel is a technique to interconnect between local networks that are separated through a public network. Research questions found looping caused by traffic issues when sending data in the MPLS service layer-2 tunneling service. Furthermore, this research...
