FIELD: radio engineering, communication.
SUBSTANCE: method of routing services "point-to-multipoint" in multi-domain network with architecture with hierarchical elements of computing channel, H-PCE contains in the child element computing channel, C-PCE, one of the domains, the stages at which define information on domain topology, wherein the generalized domain topology information includes at least one of: indications as to whether the domain is capable of supporting point-to-multipoint services; Indications as to whether the general domain topology node is capable of supporting a branch point for point-to-multipoint services; and sending information on the generalized domain topology to the parent channel calculation element, P-PCE.
EFFECT: increase in data transmission rate.
