FIELD: radio engineering, communication.
SUBSTANCE: invention relates to means for interaction between a client system in the first network domain and domain of the network supporting the technology of gateway via routing protocol as to provider communication channel (PLSB). At least two boundary bridges of backbone network (BEB) of PLSB domain are presented. Each BEB is a terminal connection point of the first network domain with a client system and a terminal point of at least single-address path determined within PLSB domain. An internodal trunk channel is provided in PLSB domain for mutual connection of at least two BEB. Phantom node is determined in PLSB domain. Phantom node has unique address in PLSB domain and is abstractly located in the internodal trunk channel in each jump from each BEB. Each BEB is configured so that an incoming packet received from the client system through connection in the first network domain is sent through a path abstractly having a root in the phantom node; and an outcoming subscriber packet intended for the client system is sent to the client system through a connection in the first network domain.
EFFECT: technical result consists in improvement of stability of connection to a network domain.
