The REsource LOcation And Discovery (RELOAD) protocol [RFC6940] recommends symmetric recursive routing (SRR) for routing messages and describes the extensions that would be required to support additional routing algorithms. In addition to SRR, two other routing options -- direct response routing (DRR) and relay peer routing (RPR) -- are also discussed in Appendix A of [RFC6940]. As we show in Section 3, DRR is advantageous over SRR in some scenarios in that DRR can reduce load (CPU and link bandwidth) on intermediate peers. For example, in a closed network where every peer is in the same address realm, DRR performs better than SRR. In other scenarios, using a combination of DRR and SRR together is more likely to provide benefits than if SRR is used alone.

  An Extension to the REsource LOcation And Discovery (RELOAD) Protocol                    to Support Direct Response Routing


   This document defines an optional extension to the REsource LOcation    And Discovery (RELOAD) protocol to support the direct response    routing mode.  RELOAD recommends symmetric recursive routing for    routing messages.  The new optional extension provides a shorter    route for responses, thereby reducing overhead on intermediate peers.    This document also describes potential cases where this extension can    be used.
