Various kinds of broadcast services, such as TV distribution and Near Video-On-Demand, will be introduced into the B{ISDN tra c. These services need wide bandwidth since they have moving images. Therefore, broadcast services will occupy a large part of the B{ISDN tra c. However, the nationwide topologies of the conventional telecommunication network are designed for point-to-point (P-P) service...

Problems of multiservice network modeling on the basis of hybrid methods – methods of graph theory and queue system are considered in the article. Model NGN-network is presented in the form of exponential Petri net. For calculation of probabilistic and time characteristics of network on the basis of Petri net analytical expression was received. On the basis of this expression calculation of tim...

Mobile Ad-hoc Network is a self configurable routing protocol. Nodes in MANET can shift freely from one place to another place and each node in MANET can take action as a transmitter, receiver and router. WiMAX is a telecommunication technology standard which provides fixed and mobile Internet access. Access Server Network (ASN) in WiMAX provides the layer 2 connectivity to the user equipments....
