1. A network device comprising a plurality of nodes packaged in one or more switching chips, the number of the plurality of nodes being 4N or 4N+2, N being an integer equal or larger than 1;
wherein each of the plurality of nodes comprises a network-side port for coupling to an external network device and at least two switch ports for coupling neighbor nodes,
wherein the plurality of nodes are connected via their switch ports to form a ring link;
wherein a first node of the plurality of nodes is configured to:
receive traffic,
transmit the traffic to a third node through a first transmission path via a second node on the ring link, the first transmission path being one of reachable paths with equal hop counts from the first node to the third node and the first transmission path comprising the second node.
