- FidoNet Message ID Proposal
- By Todd Kover
- 1:261/5016;1:261/1028
-
- Since there are many proposals for Message-IDs, for dupe-checking, and
- reply-linking, I figured, I may as well do my best to add confusion to
- things, and come up with another one. :-) In my playing around with
- different ideas, and such, I came out with the following format:
-
- ^AFMSGID:DDDYYHHMMSSLLNNNNOOOOPPPP[ZZZZ][Domain]
-
- ^AFREPLY: < Repeat of what is above >
-
- Here's a brief explanation of what each area is...
-
- DDD: (01-366) The day of the year. (Julian calendar method).
-
- YY: (0x00-0xFF) The year. Now, this only gives 255 year accuracy, but,
- if the message has been in circulation that long, then it deserves
- to be read again. :-)
-
- HH: (00-23) Hour which the message was written
-
- MM: (00-59) Minute which the message was written
-
- SS: (00-59) Seconds which the message was written
-
- LL: (0x01-0xFF) In reading NET_DEV, and FTSC, and all of the debating
- over "What happens when someone enters a message at the EXACT same
- time, on my multiline system?) Well, the best way to avoid that,
- is to either A) Set the ID while packing the message up, and only
- pack all the lines messages in, at once, or, use this option, that
- sets the line number, of the caller (0-0xFF).. I figure that there
- won't be more than 255 lines to a single node... I would opt for
- the former, but, I put this in here, to shut everyone up. :-)
-
- NNNN: (0x00-0xFFFF) The Net Number of the node, that this message
- originates from.
-
- OOOO: (0x00-0xFFFF) The Node Number of the node, that this message
- originates from.
-
- PPPP: (0x00-0xFFFF) The Point Number of the node, that this message
- originates from.
-
- ------
- Now for the Optional ones:
-
- ZZZZ: Since there is a question as to weather or not Zones should be
- implemented, and, some packages do not implement them, I figured
- that this should be optional. If it is not there, then a Domain
- address would be there, or, nothing at all.
-
- Domain: This is for the people that use these (SEADogians, for one).
- I am assuming that Domains are alphabetic characters, and no
- numbers are there (Which is probobly stupid on my part), so that
- software can distingish between Domains, and Zones.
-
- ------
-
- The FREPLY: is just teh FMSGID of the message that the message is replying
- too. That way, you can just compare.
-
-
- In order to allow dupe checking, a system has to keep a backlog of all of
- the message IDs for some period of time (say 2 weeks?) that pass through
- the system, and has to compare a new one to the old ones. If it matches,
- then the message is a dupe. This doesn't seem too efficient, since there
- are alot of messages that pass through something such as a backbone, but,
- I am sure there is some way to make it fast, I just haven't put enough
- thought into it, yet).
-
- ------
-
- One of the more nicer features about this, is that if the ID is not there,
- then it can be calculated by examinining parts of the message, and the
- header to get all of the information, and, it can be put in there. Pretty
- simple, eh?
-
- ------
-
- If you want to get in contact with me, to make contacts on this, you can
- reach me at my private node, 1:261/5016, but, since I only poll the Net-
- Coordinator once a week, or so, to pick up my NodeDiff, and FidoNews, I
- will be a little slow in responding to it. You can reach me pretty
- quickly on 1:261/1028, which is the only BBS that I frequent, just about
- daily, and, if I don't, the sysop there will tell me if there is anything
- waiting for me... Direct flames, and such things to NIL:, thank you..
