Don't know about MAE-East. These aren't important things about which to bother. VPN stands for virtual private network. Let's say a company has its offices spread over several places in a city. How are they linked? By telephone and T1 line or Tx. The phone company can handle the voice aspect, but data transfer has to have a dedicated transmission line. There are issues of privacy, security, and data integrity. You can rent space on a public carrier or you can build your own. There is another way. If DSL or cable modem can become ubiquitous, the cost to transfer data between offices can be cut significantly because the cost is 1/3 at least the cost to support a T1 line. I'm not even considering installation and maintenance. You push all that onto the carrier. Your network becomes virtual since you aren't responsible for its physical presence and has the virtue of supporting an office intranet all hooked together by phone line (DSL) or fiber optic cable (cable modem). Currently VPNs are phone line and T1 or equivalent interconnected. The only problem with it is that fiber optic cable has expansion potential with incommensurate cost increase. Once you got the cable in, you can expand with little or no cost. Also renting cable access like we do with say, @Home, is far cheaper than DSL or T1 , fractional Tx, solutions. The rub is that over time people discover this advantage and everyone gets on board. The backbone breaks unless a technology like SR comes along to alleviate the problem. Hope you are starting to see the purpose of this thread. Frank participates in the discussion about VoIP. Voice over Internet Protocol. This is telephony using tv cable modem or using higher speed digital transfers over phone line. VoIP will be of value to your business because eventually it will be cheaper and better than what you have now. This will be especially true when all transmissions are carried to the point of use by fiber optic cable. This is usually the PC or Set top box interfaces. From those all other communications devices will be supported. Don't know Boardwalk. If you want a good source of these technologies, you only need to come to SI. Here , for example, you can ask Frank or Bob Zacks where to go for materials. Bob can direct you to sources on the net. There is little reason to go anywhere but to the net. Do a profile lookup and send Bob a private message with your request.

... For that reason, I assumed, and still assume that MAE-East is situated in Northern Virginia, in the location I described. Do you know if I am right? If not, where is it? ... I think its on the Tyson's II side of 123. See: saxophone.agora.com ...MAE (metropolitan area exchange) East, which handles at least one-third of all Internet traffic worldwide, is located in an underground parking garage in McLean, Va. "All it needs is some senior citizen in a Suburban to hit the gas instead of the brake, and there goes the NAP [network access point]," says Rodney Joffe, chief technical officer for Genuity Inc. (San Francisco), an Internet service provider (ISP).... ww
