Jeremy, You're so funny. ;-) Only Bob Matecalfe's zany antics entertain me more than this [printed] drivel.

I think he said an OC-12c version will be in production soon. Perhaps we could ask Jim to add some firmware to grab the SA/DA pairs and dump them to a log processor in the same box. Unfortunately, this would not help unless the path went through an ATM segment somewhere on the network. ..mike..

That's _host address_ matrix, not network address matrix. It is at least three orders of magnitude bigger. Another datum -- the hot spot on route cache on ICM's routers from hell is about 40% on networks addresses. >The number of cell entries is not equal to the number of routes squared. >It doesn't happen. No, nobody said that. That's why my figures are in 100M range, not 2000000 bil which is the size of "full host matrix". >Even if your router is expiring 20,000 flows per second, >it only comes out to about 667 packets per second to the workstation, >which is pretty low even for older workstations with fairly weak CPUs by >modern standards. An Alpha can handle it w/o even breaking a sweat. 20k flows per second? You must be kidding. The average flow length (as derived from Sean's stats) is 20 packets. I.e. 20 kfps is what you get from a single OC-3 working at the wire speed. --vadim

I read a Dow Jones report entitled: WorldCOM-MFS merger Spells Trouble for Baby Bells WorldCom (still called WilTel by most Internet folks) bought MFS for (at Friday's stock prices) $47.78 per share in stock. In reaction, WorldCom stock is down, MFS stock is up. >From an operations standpoint, the options of who to work with are getting narrower... -- Jim Browning ---------- From: Bill Woodcock[SMTP:woody@zocalo.net] Sent: Monday, August 26, 1996 6:52 AM LDDS WorldCom?

I got this second-hand from a non-techie who was listening to the noon news on NPR, so I have no idea what he _actually_ heard. :-) That would at least make sense, even if it's not particularly auspicious.

It's Worldcom, Inc., aka LDDS Worldcom, who recently bought Wiltel. See http://www.mfst.com for the press release. Steve

Well, the value of the deal has gone down to about $12.4 billion since "WorldCom"'s stock has taken a tumble today, down almost 14%. The deal is just a stock swap, so they really don't have that much cash. But the new MFS WorldCom is said to rival the baby bells in market cap, and it will be bigger than MCI. The interesting part of it all is that now there is one company that can provide the local loop, the inter-exchange circuit, and the Internet port.
