Abstract
Network interworking with no cross-domain state may be provided. First, an edge node may receive a packet from an intermediate node in a first domain. The edge node may be between the first domain and a second domain. Next, the edge node may pop, in response to a first Service Identifier (SID) in the packet, headers corresponding to the first domain from the packet. The edge node may then push, in response to the first SID, a label stack corresponding to the second domain onto the packet. The first SID may include data corresponding to the label stack. Then the edge node may route the packet to the second domain destine to an end node in the second domain.
