Abstract
Some embodiments provide a network that includes (i) multiple forwarding elements, (ii) a set of one or more global control plane (GCP) servers, and (iii) multiple end-node machines. The GCP servers maintain topological information about connections between the forwarding elements. Each of the end-node machines receives the topological information, identifies a source-routing path for a message sent by the machine, and embeds the source-routing path in a source-routing message header that includes an egress port for each forwarding element along the path.
