This has come up multiple times at the IETF and elsewhere. There are BGP
router servers, which are especially used at inter-exchange points, there's
the PCE (Path Computation Element), which is used mainly with MPLS, GMPLS,
and Segment Routing, and Software Defined Networking (SDN) in general,
which uses a centralized route server rather than distributed path
computation. There are other examples as well.

Cheers,
