<p class="MsoNormal">Dear Wolfgang,<o:p></o:p></p>
<p class="MsoNormal">In order to facilitate the future possibility of using some of our current FRs in other node types besides ESLTs (e.g., on space nodes) , we decided to remove the “forward” and “return” prefixes of FR names/classifiers when the sender/receiver
nature of the FR could be inferred from other elements of the name – e.g., “Mux” designates the sender side (and thus the forward link from the ESLT’s perspective). However, we did not discuss extending this renaming to the FR Sets that contain those FRs.

<p class="MsoNormal">Here is my list of proposed modified FR St names. If you agree we can use these in the SANA FRs and the FR Reference Model:<o:p></o:p></p>
