PHILADELPHIA OS/2 USER GROUP . http://www.phillyos2.org The Philadelphia OS/2 User Group invites all interested computer users to attend the May monthly meeting: . WEDNESDAY, MAY 23, 2000 7:00 - 10:00 PM . The Episcopal Academy, 376 N. Latches Lane, Merion, PA . *** MAY 23rd FEATURE PRESENTATION *** . -- OPTICAL NETWORKING FOR OS/2 -- Implementation of optical networks on OS/2 will be the the main feature at the May 23rd meeting, to be presented by Philadelphia OS/2 member Vadim Kavalerov. TCP/IP and Ethernet are the two computer networking technologies developed in the 1970s that became de facto standards in the early 80's, and are currently used in all BSD-derived operating systems, including OS/2. In the last decade, several high-speed alternatives have emerged to address major shortcomings of insufficient speed, poor bandwidth utilization, best-effort instead of guaranteed delivery, and lack of network management protocols. Asynchronous transfer mode (ATM) is one such major alternative technology. ATM is based upon cell-switching rather than packet switching. It was built by telecommunication companies in order to integrate voice, video and data networks into one. ATM standard speeds range from 155 Mbps (OC-3) & 622 Mbps (OC-12) up to 40 Gbps. ATM is currently the principal backbone networking technology; it carries over 60% of the Internet traffic. In the mid-90's, the leading developers of ATM envisioned it to replace TCP/IP and Ethernet in the near future, and deliver voice and video to the desktop. However, due to high initial cost and complexity, its application has been limited to Wide Area Networks (WAN). Still, ATM adapters for the desktop computers are available, and there are several of them that work on OS/2. They provide LAN Emulation that can be used to integrate ATM, Token-Ring, and Ethernet networks into one. Vadim will review the main principles behind ATM technology, and demonstrate a small ATM network on OS/2 using PCI adapters from Fore Systems Fore PCA-200E & LE155, and Olicom RapidFire 616x, and an Olicom 9200 ATM backbone switch. He will show how optical fiber and CAT-5 copper cabling can be used interchangeably on a 155 Mbps LAN. If time permits, switch configuration and management procedures will also be demonstrated. Barry Mann's REXX Section tutorial this month will cover writing procedures. Specific topics will include writing procedures, passing parameters, returning results, and variable scope. We will also field questions about the previous exercises. Other agenda items include U/G business matters, OS/2 news, Q&A session, new releases & raffles. Free light refreshments. Philadelphia OS/2 meetings are open and free for OS/2 users, their guests and others interested in learning about OS/2 and associated technologies. .
