Millions) Subject: Measuring Network Availability Organization: Sobeco Ernst & Young Date: Tue, 8 Mar 1994 19:12:41 GMT Hi, I have a question that has been puzzling me for some time. I was involved in a project, where we helped to migrate a companies user base from an IBM mainframe / SNA / 3270 terminal environment to a UNIX / TCP/IP / vt220 / terminal server environment. I can remember one of IBM network type people made a comment about how they guarantee their users 99.8% network availability and he was skeptical that we would be able to match that in the new environment. Now my question is simply this: How do you a) define and b) measure 'network availability'? Particularly in the context of LANs and WANs. I, unfortunately, did not have opportunity to take this up the the IBM network type who made the original comment, I would have been most interested in his definition. It would seem that the definition is the key. Defined one way it could be interpreted as 'No one cut the cable, therefore it is available' and thus you can easily attain 99.8%. At the other end of the scale, you could define it such that the network is considered unavailable if some one turns off their PC. More realistic would be something somewhere in the middle. I would be very interested in comments from people who have defined this and do measure it. stacy stacy@sobeco.com stacy@sobeco.ca sobeco!stacy ------------------------------ Date: Tue, 08 Mar 1994 18:01:46 CET From: JBUSTAMANTE@vms.eurokom.ie Subject: Information Market Guide (IM-GUIDE) Organization: EuroKom Conferencing Service WHAT IS I'M GUIDE ?

Years ago, the FCC's response would have been to go out and padlock the transmitter after shutting it off; I guess these days the big money involved with major radio stations doesn't allow that to happen.

As long as their machines haven't run out of paper, you can use the phone lines to deliver a message about irresponsible uses of telecom to them in printed form. Doug Oke - Vancouver, Canada Doug_Oke@mindlink.bc.ca [TELECOM Digest Editor's Note: Good thinking! The fax number at the WLUP general offices is 312-440-9377. But keep your messages brief (say, less than 10-12 pages in length) and non-abusive. You might want to fax them copies of pertinent FCC regulations, copies of scripts from old Jack Benny radio shows to show them what 'comedy programs' were like years ago and perhaps some pages from the Chicago phone directory to show them a list of people who might be or were possibly affected by McCann's 'game'. Say Doug, do you get AM-1000 out there in Vancouver at night? I know there is a station somewhere around Calgary, Alberta playing heavy rock music which comes in here in Chicago at night some- times. When we get the signal it comes in like gangbusters even louder than some of the locals. AM radio signals are amazing things.

The rate (with the special discount plan) is $0.73 now, but will be (again with the special discount plan) $0.78 next month. That *is* an increase; why? None of the other countries mentioned in the ad has any differential. Also, one of the ads like this that I saw listed the "regular price" rates for India, and they *are* scheduled to increase on 4/1/94.

The soldiers were using radiotelephones that were connected to the military's satelite system. And here is how far the world has changed; some of the critical classified information sent by the military was transmitted over satelites leased from Russia! The reporters were using Inmarsat telephones. They're fine if you want to pay about $9 a minute more than typical overseas calls, e.g. a long distance call from the U.S. to Saudi Arabia is about $1.20 a minute, while Inmarsat charges about $10 a minute. Oh, and don't forget the $10,000 to $50,000 for the transmitting station.

In "To Sail Beyond the Sunset," A son asks his mother, "In Dallas the TV telephones are all stereo; why is Kansas City still using flatties?" to which his mother responds, "Donald, whenever any question begins 'Why don't they' the answer is almost always 'Money'." > The only reason I've heard so far is that the RBOCs must be "de- > regulated" before they can accept/deliver Inter-LATA originating > numbers. Some people in some cities have noted getting Caller-ID information from people in other states, who are long distance calls. It's a political, not a technical question. What it probably comes down to is that the local telcos believe that providing calling party information is a valuable service for which they think they shouldn't have to provide it without compensation on calls delivered to a distant point, where the the distant party benefits without the local company getting some cut. > This doesn't seem to make much sense. Perhaps it's just a matter > of working out which carrier charges who and for how much or is > there another reason? Don't forget, if calling number delivery becomes much more available, some companies can dispense with T1s for 800 numbers and get the same thing without having to pay for T1 trunks to get real-time delivery of calling party numbers. Since an 800 call almost always comes in as just an ordinary call terminated on ordinary phone lines, the CNID information should be available in real time to me, with my $10 a month 800 number from Sprint as it is to some company paying $2000 a month for T1 trunks.

The 'cat cracker' is a device that uses a catalyst (cat for short) to 'crack' complex hydrocarbon molecules, which is to say to break very complex molecules into simpler molecules. It's highly explosive, of course, because you're dealing with petroleum and heating it up to work on massaging its molecular structure.

A few years ago while unemployed, I found that I was getting crosstalk on my phone line from some business. I called SouthWestern Bell and they fixed the problem. A number of months later when I was home during the day, I noticed that the problem was back, so I called SWB again and they "fixed" the problem again. Things were fine again for a few months and then one day I was on my modem line dialing into work and the line went completely dead. I stepped out onto my front porch and noted a SWB repair truck parked in front of Jeff's house across the street. I walked over to the truck and told the guy what happened. He asked me "Is your number xxx-xxxx?" I answered that it was, and he muttered "Damn! Is it completely dead?" Yes. "Okay, I'll take care of it once and for all." He put a tone generator on my line and walked down the street with a coil on the end of a poll until he stopped getting the signal. He then climbed up the poll and discovered an ant colony in the wiring. By 10PM he had my line working and by noon the next day, he'd patched up everything and evicted the ants. I don't know of any line problems in my neighborhood since, but I could be lucky. It seems that this crosstalk problem had been going on for years and every time someone would complain about it, rather than fixing it they simply patched a different line into the bad pair. They made a point of mixing business and residencial lines on the theory that we'd be less likely to be using the lines at the same time. Until the line completely failed, they didn't have an easy way to localize the problem, so they punted.
