The SL used by the app should be based on what comes back in either a SA PathRecord or possibly MCMemberRecord response (for IPoIB UD). For RDMA CM based apps, the query is based on Service ID and either QoS class (added by QoS Annex) or traffic class depending on the address family used. > If yes, is there a list somewhere so if we force the service type in an > application we don't conflict with an existing one. QoS class (QoS Annex) can be per DiffServ (see QoS Annex). I don't understand what you mean by service type not conflicting unless you mean service ID rather than type. Service IDs are standardized by IETF or IBTA. There's also provision for local OS or external organizations as well. See IBA 1.2.1 Annex A3 if that's what you mean. -- Hal > Nicolas _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
