The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

Conferencing conference calls

It's been over a year, and we're still not quite there with the “virtual gaming table” that Bob wants.

After several months we've given up on sound—the ability for us to talk over the Internet using our voices rather than text. It was a painful lesson to learn, and yet there's still a person or two that wants to keep trying.

But the technology isn't there yet.

This is how we're currently setup—the image shows the private networks (red areas) and their connections (green areas) to the Internet (blue area) with the lines widths representing the relative connection speed (hence the thickest connections are local networks; the DSL connections are thinner and the thinnest connection being Lorie stuck out on a 56k dialup through AOL). And assuming we're trying to use “voice” instead of the gaming specific chat software we usually use. And assuming that NAT issues (dealing with the translation of network traffice between the “private” networks and the “public” Internet) aren't an issue (and they are since most, if not all, VoIP type protocols assume both sides are on “public” networks) and assuming that the VoIP on each user's computer sends a copy to everybody else in the “conference call” then it works like this: Fritz says something, and his computer then has to copy it out to eight other players, five copies of which are headed towards Bob's house (the big red area on the right). And what if Lorie, on her 56k dialup says something? Her connection is suddenly swamped sending out all that data.

And heaven help Bob's network if everybody at the table starts talking.

Things are only marginally better if there's a central server handling the messages. Sure, then everybody's computer only sends a single stream to the central server, which then streams copies out to everybody, but that still leaves five streams headed towards Bob's house.

Today I was taking with Dan, the network engineer here at the office, and he mentioned Asterisk, an open source PBX. Put one Asterisk server out on the internet, another one at Bob's house. Those not at Bob's do a “conference call” to the server on the Internet; those at Bob's house do a “conference call” to the server at his house, and possibly with some hacking, have the two Asterisk servers pass the “conference call” data between them.

It might be possible, but, and this is a big one, but, it's more possible that we can do this on a stupid network than if we waited for this functionality from the “intelligent phone network” (“We're the phone company, we don't have to care!”).

Obligatory Links

Obligatory Miscellaneous

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
