History

Rad was founded by brothers Yehuda and Zohar

Zohar Zisapel

Zohar Zisapel , is a successful Israeli entrepreneur in Israel’s advanced hi-tech industry. The RAD Group of companies he co-founded with his brother, Yehuda Zisapel, has been called "the world's most successful incubator" of telecom-related start-ups by Business 2.0 magazine.The Zisapels' RAD...

Zisapel in 1981, as a spin-off from Bynet, a Networking hardware distribution company founded by Yehuda in 1973. Their goal was to develop their own products; the company was simply named RAD, for Research And Development.

RAD first successful product was a miniature (in 1980’s standards) computer modem. The product quickly became a commercial success, and by 1985, RAD annual revenues reached $5.5 million USD. This initial product line has evolved into RAD Data Communications, the largest company within the RAD Group.

Products

RAD's research, development and engineering includes TDM

Time-division multiplexing

Time-division multiplexing is a type of digital multiplexing in which two or more bit streams or signals are transferred apparently simultaneously as sub-channels in one communication channel, but are physically taking turns on the channel. The time domain is divided into several recurrent...

, Ethernet

Ethernet

Ethernet is a family of computer networking technologies for local area networks commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies....

, MPLS

Mpls

MPLS or Mpls can refer to:* Minneapolis, Minnesota, United States* Multiprotocol Label Switching, a data-carrying mechanism in computer networking...

, IP

Internet Protocol

The Internet Protocol is the principal communications protocol used for relaying datagrams across an internetwork using the Internet Protocol Suite...

, ATM

Asynchronous Transfer Mode

Asynchronous Transfer Mode is a standard switching technique designed to unify telecommunication and computer networks. It uses asynchronous time-division multiplexing, and it encodes data into small, fixed-sized cells. This differs from approaches such as the Internet Protocol or Ethernet that...

, pseudowire circuit emulation and service emulation, clock synchronization

Clock synchronization

Clock synchronization is a problem from computer science and engineering which deals with the idea that internal clocks of several computers may differ. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at...
