Grant, The Verb portion deals with the data path operations (after the connection was established), the connection establishment process is very different IB CM is implemented on top of the verbs, an iWarp specific CM would also need to be developed in parallel (interacts with the TCP stack ..), and common ULPs need a single mechanism to use both (in the DAPL case a BSD like API using IP addresses) Again I'm not saying kDAPL is the ultimate solution or that it will last in its current form, its just the only thing we can use today, if someone would come with a better implementation we can just change iSER In one of the previous threads I suggested building a hybrid layer that uses the current verb APIs for verb type operations, and the DAPL code for the connection establishment, resulting in a simpler/shorter code, this would present a middle ground addressing the concerns on both sides Yaron _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
