Proposed revision: An XP sender (not necessarily the initial XP sender) wants the XP message to be handled with specific quality of service as it traverses the XP message path to include multiple XP Processing intermediaries. Information in the XP message is used to select appropriate QoS mechanisms (e.g., RSVP [1], Diffserv [2], MPLS [3] , etc.). Selection of QoS may be constrained by QoS policies [4], Service Level Agreements (SLAs) [5], Service Level Specifications (SLS) [6]. Previous version: An XP Processing Intermediary on the edge of a public network may add XP Blocks and handle interfaces to lower layer QoS mechanisms (e.g., RSVP, MPLS, DiffServ, COPS Policy info, etc.) for the next hop in the message path to the next XP Processing Intermediary. An XP Block may provide information used by the XP Processing Intermediary to determine what QoS to select, what Service Level Agreements (SLAs) and what service level specifications (SLSs) [6] may apply.
