METHOD OF ROUTING TRAFFIC, HAVING PRIORITY CLASS IN COMMUNICATION NETWORK, INCLUDING TWO AND MORE OPERATORS Russian patent published in 2017 - IPC H04L12/70 

FIELD: information technology.

SUBSTANCE: setting the fragment of the communication network area, including N≥2 networks of operators, allocating trusted subscribers served on a given fragment of communication network connected to N≥2 networks of operators, and setting the stored multi-function subscriber terminals (MSTs) having stored IP addresses by the number of connected networks respectively, forming a set M = (m₁, m₂, … m_j, … m_M) traffic routes of traffic having a priority class of service for all subscribers through the established MSTs, determining the shortest route m_j from a plurality of possible ones, forming a network datagram with a sender S_A and recipient S_B address, encapsulating datagram in the "Data" field of new datagram with the address of receiver S_B and the address of output interface of the nearest MST of sender S_Vj on m_j route, repeating the encapsulation action until the datagram is formed with the sender address S_A and the address of input interface of the nearest receiver MST S₁, transmitting generated datagram to the communication channel which is received on MST with the address of input interface S₁ and output S₂, sending a network packet on.

EFFECT: improving network security.
