For draft 2) and 3) I have seen recent updates and I did talk with some of the authors. The feedback I got so far, is that the drafts are ready for WGLC. I have kindly asked the chairs to get the Working Group Last calls started on Monday, Nov 17, in order to move these drafts further towards AD review and the following steps. Further, the plan is to close the working group on December 1st, after having the working group drafts completed the WGLC. Thanks for the work and let me know if you have any questions, comments or suggestions!

A few comments (mostly nits): * "Given the above, and in the light of the significant increase of overall data volume in 3G networks, Deep-Packet-Inspection (DPI) is often considered a desirable function to have in the EPC -- despite..." EPC -> EPS (?) If it is EPC, then expand it as this is the first time it's appearing. * 2.1. ConEx as a Basis for Traffic Management " 1. It can enable or enhance flow policy-based traffic management. At present, DPI-based resource management is often used to prioritize certain application classes with respect to others in overload situations,... 2. It can reduce the need for complex DPI by allowing for a bulk packet traffic management system that does not have to consider the application classes flows belong to and individual sessions... " Both 1 and 2 are attempting to use ConEx to be used in place of the more complex DPI based systems. But I think you are attempting to enumerate two _different_ ways in which ConEx can be used to reduce the need for DPI. I understand (1), but (2) is less clear. Could you in particular either edit the first para of point# 2 above, to _clearly_ state how it's different from point #1. * 2.3 Accounting for Congestion Volume "This would not require any new interface (reference points) at all." What do you mean by this sentence - reference points? * 2.4 Partial vs. Full Deployment About this point: the prior points 2.1 - 2.3 actually adhere to the title of this Section "ConEx as a Basis for Traffic Management". Partial versus Full doesn't exactly fill this category. It reads more about: if ConEx were to be deployed in mobile networks then a partial deployment also makes sense and a full deployment as such isn't a necessary condition for sing ConEx. Is this correct? And if so, should it belong here in this section? It seems to be that this section would be more apt in Section 3 where you are already talking about deployment scenarios. * 3.1. Possible Deployment Scenarios Figures 1, 2, 3 have some abbreviations S-GW and P-GW that you don't really mention in the description. Could you expand these somewhere? If not necessary, then remove these abbreviations. * 3.1. Possible Deployment Scenarios Figure 4 has some further acronyms not referred to in the text: DL congestion? * " We consider all three scenarios to be relevant and believe that all of them are within the scope of the CONEX WG charter. A more detailed description will be provided in a future version of this document." Remove this? Do we expect a future version of this doc.? * 3.2.2. CONEX Functions in the Mobile Network "In the EPS, per-user information is normally part of the user profile (stored in the HSS) that would be accessed by PCC entities such as the PCRF for dynamic updates, enforcement etc." What is PCC, PCRF, HSS? * 4. Summary Shorten the summary. Repetition of text from the main sections, so can be brief here. The four classifications are useful. Thanks!

Some comments below: * Introduction "First congestion information have to be extracted from loss or ECN feedback in TCP as described in section 3"... ". Remove the extra quotes. * "It is therefore recommend to use the SACK extension when using TCP with ConEx." It is therefore recommended... * " This document describes congestion accounting for both TCP with and without the Selective Acknowledgment (SACK) extension [RFC2018] in section 3.1. ... The detailed mechanism to respectively set the L bit in response to loss- based congestion feedback signal is given in section 4.1." "The congestion accounting for both, with the classic ECN feedback as well as a more accurate ECN feedback are explained in detail in section 3.2 while the setting of the E bit in response to ECN-based congestion feedback is again detailed in section 4.1." This jumps around around describing Section 3.1 -> Section 4.1 -> Section 3.2 -> and back to Section 4.1 Suggestion is to consolidate to keep all the Section 3 material by itself and Section 4 material by itself. Also the last three paragraphs of the Intro. seem disconnected with the rest. The para starting with "Section 2 provides an overview of the needed modifications for TCP senders to implement ConEx..." already laid out the Section contents. * Accounting Congestion Reword the first sentence. A ConEx sender maintains two counters: one that accounts congestion byte-wise based on the congestion information received by loss detection, and a second that accounts for ECN based congestion feedback. * 3.1.1 Without SACK Support The last para of Section 3.1.1: "At this point of time in the transmission, in the worst case, all packets in flight minus three that trigged the dupACks could have been lost. For each retransmission that is sent, the LEG will still be increased but the LEC will also be decreased by the payload size of the retransmission. During the following RTT, LEC should be reduced by SMSS for each ACK that is received. Thus after one RTT the LEC estimates the number of outstanding bytes that should be ConEx L marked. To not further delay this information, now LEG should be increased by LEC. From then on every following retransmission should only reduce the LEC and not increase the LEG until the LEC is zero, as those bytes were already accounted." Have you considered putting the above in a pseudo code: On a retransmission: XXX On receipt of ACK: XXX * 5. Loss of ConEx information "Of course also packets..." -> Packets carrying ConEx can also get lost. 6. Timeliness of the ConEx Signals nodewith -> node with avoiad -> avoid
