Greg and all,

> If you have any additional topics you wish to discuss during the space 
> link protocol WG meetings, please let me know ASAP.

I'd like to discuss the following things:

1) Green Book on the Space Data Link Protocols
2) revised Green Book on Overview of the Space Link Protocols
3) revised Green Book on the Space Packet Protocol

I will distribute the above documents at least two weeks prior to the 
meeting.

Best regards,
Takahiro Yamada.

All,

Attached is a proposed change to the CCSDS Proximity-1 Space Data Link 
Protocol half duplex State Table, See Table 6-10 Event E38 and E39.

The change to E38 is only a comment providing clarification about the 
result of the action taken.

The change to E39 involves to removal of the test of X=2 (a termination state).

I have put this change on the agenda for discussion on Wed. May 12.

Please let me know if you have any comments concerning this proposed change.

best regards,

Greg Kazz

Greg,

I have to chair the Systems Architecture WG meeting all day May 11, 
but I think I can join your WG to talk about my books using a break in 
my meeting. I will distribute the books by the end of this week, and 
if there are no major issues on them, the session on them will be very 
short. I will process minor and editorial comments on them off-line.

I look forward to seeing you again in Montreal.

Best regards,
Takahiro Yamada.

Message-ID: <4.2.2.20040420094207.010a1500@mail1.jpl.nasa.gov>

Dear All,

Last week I emailed to all of you draft Pink sheets on a proposed change to 
the Half-duplex state table (Table 6-10, Session Establishment and Data 
Services)  in the current Proximity-1 Space Link Protocol - Data Link Layer 
Blue Book. However, I forgot to provide you the rationale for this change.

Event 39 enables the token to be passed to the partnered transceiver, 
enabling it to transmit. One can reach Event 39 by two paths. Either the 
send_duration timer has expired, meaning it's time to give up the token, 
i.e., the "right to transmit" or the transceiver has (either completely for 
the pass or temporarily) run of data to transmit before the timer has 
expired. In either case, the test for X=2 is  unnecessary in order to 
transition from State 50 to State 56.

Greg

Subject: [Sls-slp] Draft Green Book on Space Data Link Protocols
Message-ID: <408A9110.2030205@pub.isas.ac.jp>

Dear CCSDS Colleagues,

Attached please find a copy of the first draft of the Green Book on 
the Space Data Link Protocols (which are TM, TC and AOS Space Data 
Link Protocols).

<< About this book >>

CCSDS published separate Green Books on Telemetry, Telecommand, and 
AOS protocol suites, but I explained the Data Link Layer portion of 
all of these suites in this book. Actually, the Space Data Link 
Protocols share a lot of features (e.g., use of Virtual Channels, 
handling of Packets, etc.) and therefore I hope you will find this 
format meaningful.

The following are the major sections of this book:

Section 2: Overview,
Section 3: Services,
Section 4: Mechanisms.

Some of you may think mechanisms are more important than services and 
therefore should be explained earlier than services. Mechanisms are 
important to implementers of these protocols but services are 
important to users who select protocols as well as to implementers. 
Therefore I explained services before mechanisms and this is the order 
I used in all of my books.

<< About the file >>

Since diagrams move around when a Word document crosses an ocean, I 
only distribute a PDF file. But if you need a Word file, please let me 
know.

<< Please review it>>

I'd appreciate it if you could review the book and give me any feedback.

Since this book is on one of the most important subjects of CCSDS, I 
also distribute it to the CESG members. I welcome any comments from 
any Area or WG.

<< Another GB >>

I edited and distributed another Green Book on the Space Packet 
Protocol (which is the Packet portion of the suites) in August of last 
year. Since I have received some feedback on it, I will revise and 
distribute it in a few days.

Best regards,
Takahiro Yamada

Message-ID: <408DFF32.70605@pub.isas.ac.jp>

Dear CCSDS Colleagues,

Attached please find a copy of the second draft of the Green Book on 
the Space Packet Protocol.

<< About this Book >>

I distributed the first draft in August of last year and received 
comments from Peter Shames and Dai Stanton. Based on the received 
comments, I rewrote sections 3.2, 3.3, 3.4 and 4.1. The other sections 
are mostly the same as those in the first draft.

This GB has the same structure as the GB on the Space Data Link 
Protocols I distributed a few days ago, except that the overview 
section and the services section are combined into a single section in 
this GB.

<< About the file >>

Since diagrams move around when a Word document crosses an ocean, I 
only distribute a PDF file. But if you need a Word file, please let me

All,

For those of you involved in Proximity-1, attached is an updated draft 
version of the Proximity-1 Space Link Protocol Green Book. If you turn on 
the revision feature in Word, you can view the changes made to the early 
draft version.

In Word, go to tools, track changes, highlight changes.

Please let me know if you have any comments concerning this Green book.

As per the agenda that I sent out to all, we will be discussing the Green 
book on Wed. May 12 in Montreal.

best regards,

Greg
