Soft Switches

The term soft switch is not defined in a standard… meaning that marketing departments at different equipment and software manufacturers use the same term to describe different things.

A switch, in its simplest form, is a device that causes communications to happen from one point to one other particular point, often when there are multiple “other” points to choose from.

A traditional Central Office (CO) telephone switch might be called a “hard” switch, since it has physical line cards that terminate loops. The switching software running on the computer which is the CO switch directs traffic between a line card and a trunk or between two line cards during a phone call.

The term soft switch is used to mean a computer running switching software that does not have telephone line cards – the communications are instead directed to the correct destination by routers routing packets, a software function.

Digitally-Signed Email: Authentication and Digital Signatures

E-mail was one of the first “killer apps” on the Internet, and has been a major contributor to increases in productivity over the past ten years. Of course, along with email came the scourge of spam. Criminals infect computers with trojan horse programs, creating collections of machines they control remotely to send millions of unsolicited offers for fake watches, pirated software, phony medications and ecard invitations to infect your computer.

As spam reaches 30, 40 or even 100 unwanted messages per day on a targeted account, it is becoming essential to automatically separate legitimate messages from spam. One tool available to senders of legitimate emails to aid the recipient in this process is to digitally sign their messages, allowing the recipient to establish a level of comfort that the message actually came from the indicated sender.

The IP-PSTN

The Packet-Switched Telecommunications Network

Over the past fifty years, several attempts have been made to develop converged networks: networks with “dial tone” that supports all communications: speech, music, text, graphics, images and video. For a number of reasons, convergence strategies employing ISDN and ATM were unsuccessful and did not gain critical mass. This time, it appears that packet-switched network service using IP will gain enough momentum to become the new kind of plain ordinary telecommunications service.
