Segment Routing encodes the segment sequence representing the forwarding path in the packet header. As the packet is transmitted, the receiver parses the segment sequence after receiving the packet. If the top segment identifier of the segment sequence is the local node, the identifier is displayed, and then the next step is processed. If it is not the local node, the packet is forwarded to the next node by using the ECMP (Equal Cost Multiple Path) mode.
