In addition to the telecommunications-related citations mentioned by @balaji.bandi, we often use the term backhauling to describe forcing traffic to traverse a path that's not optimum so that we can put it through certain services at a remote location. For instance, forcing a branch office's Internet traffic to go back to the main office for enforcement of security policy and logging rather than directly out via the local Internet circuit.
You have a head office and remote branch offices. All sites have Internet connections. All remote branch offices have site-site VPN to the head office (maybe it goes via the Internet circuit, maybe it's MPLS or some other private line - doesn't matter).
Traffic from a branch site is destined for the Internet. We force that traffic to transit the head office instead of going directly out the local connection.
