Systems and methods are provided for congestion notification in network communications, including multi-protocol label switching (MPLS) network communications. In one or more implementations, an MPLS node that receives a data packet and detects congestion may generate a cloned copy of the data packet, add congestion information, such as a congestion notification label and a congestion notification header, into the data packet, and forward the cloned copy with the congestion notification label and the congestion notification header to a next MPLS node. The next MLPS node may, responsive to receiving the cloned copy with the congestion information, provide one packet with the congestion information to a subsequent node, and another packet with the congestion information to the node from which the cloned copy was received.
