FIELD: data transmission networks.
SUBSTANCE: in accordance to the invention, value of header or a mark mentioned in given document as identifier of source station (SSID), is added to the header of encapsulated packet, for example, by adding SSID as a mark to the bottom stack of marks of multi-protocol commutation based on mark (MPLS). SSID includes unique identifier, which identifies the network boundary router of provider who is the source of the packet (PE). In certain variants of realization the IP-address of outgoing PE may be used as SSID for that PE. The PE which receives given packet, may then link the MAC-address of Ethernet source for received TLS traffic, for example, to outgoing PE. When an SSID of outgoing PE is available, receiving PE may determine, which commutation route of mark (LSP) should be used for sending Ethernet traffic to station with determined MAC-address.
EFFECT: reduction of marks in the address of the source station.
