  The paper discusses actual task of ensuring the quality of services in
information networks with fractal traffic. The generalized approach to traffic
management and quality of service based on the account of multifractal
properties of the network traffic is proposed. To describe the multifractal
traffic properties, it is proposed to use the Hurst exponent, the range of
generalized Hurst exponent and coefficient of variation. Methods of preventing
of network overload in communication node, routing cost calculation and load
balancing, which based on fractal properties of traffic are presented. The
results of simulation have shown that the joint use of the proposed methods can
significantly improve the quality of service network.
