Marker PDU Aligned Framing for TCP Specification Status of This MemoThis document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. AbstractMarker PDU Aligned Framing (MPA) is designed to work as an "adaptation layer" between TCP and the Direct Data Placement protocol (DDP) as described in RFC 5041. It preserves the reliable, in-order delivery of TCP, while adding the preservation of higher-level protocol record boundaries that DDP requires. MPA is fully compliant with applicable TCP RFCs and can be utilized with existing TCP implementations. MPA also supports integrated implementations that combine TCP, MPA and DDP to reduce buffering requirements in the implementation and improve performance at the system level.
