APB: Ellen Deleganes

The RDDP drafts are in the final stage of author review before
publication as RFCs.  In order to complete this process,
we need to locate Ellen Deleganes, as her email address
in the draft (ellen.m.deleganes <at> intel.com) returns an error.

Ellen or anyone who knows how to contact her should send
me email ASAP.

Thanks,
--David (rddp WG chair)

This document analyzes security issues around implementation and 
use of the Direct Data Placement Protocol (DDP) and Remote Direct 
Memory Access Protocol (RDMAP).  It first defines an architectural 
model for an RDMA Network Interface Card (RNIC), which can 
implement DDP or RDMAP and DDP.  The document reviews various 
attacks against the resources defined in the architectural model 
and the countermeasures that can be used to protect the system.
Attacks are grouped into those that can be mitigated by using secure

Marker 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

It compares and contrasts the different transport options over IP
that DDP can use, provides guidance to ULP developers on choosing
between available transports and/or how to be indifferent to the
specific transport layer used, compares use of DDP with direct use of
the supporting transports, and compares DDP over IP transports with

intermediate buffers.  [STANDARDS TRACK]
