Claim:
1. A device comprising: a plurality of shelf controllers to populate a forwarding table used to forward data packets via the device; and a plurality of interface unit controllers, where a first interface unit controller, of the plurality of interface unit controllers, is to: receive a first message from another device, the first message being a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) message, select a shelf controller, of the plurality of shelf controllers, to receive the first message, and transmit the first message to the selected shelf controller, where the shelf controller programs a connection, such that packets are forwarded via a data plane of the device based on the message, where the first message includes one or more identifiers, and where a second interface unit controller, of the plurality of interface unit controllers, is to: receive a second message, where the second message is received, by the second interface unit controller, after the first interface unit controller message is received, by the first interface unit controller, select the shelf controller to receive the second message when one or more identifiers included in the second message match the one or more identifiers included in the first message, and transmit the second message to the shelf controller based on the selection of the shelf controller to receive the second message, receive a third message via a port of the third interface unit controller, determine whether a session already exists for the third message, the session being a label-switched path in a Multiprotocol Label Switching (MPLS) network.
