The Contractor shall transmit the lockbox files daily according to the information below: Transmission protocol shall be based on an industry standard compatible with IBMs Systems Network Architecture
(SNA); transmissions protocol should have the ability to be upgraded to TCP/IP as specified by the Virginia Information Technologies Agency (VITA).
IP-DLC Link Service supports industry-standard Systems Network Architecture
(SNA) over IP routing so that branch-deployed and centrally deployed HIS 2004 computers can connect directly to z900 mainframes via high-speed IP networks.
Optical Ethernet is transparent to Layer 3 transport and routing protocols, important because many enterprises have a large installed base of legacy protocols, most notably Systems Network Architecture
(IBM) and Internet Packet Exchange (Novell).
Historically, mainframes and open systems computing environments have been islands of information with relatively slow links between them using file transfer technology over SNA (Systems Network Architecture
) and IP data networks.
The retailer's project calls for replacing IBM's protocol, Systems Network Architecture
, or SNA, with the Internet protocol known as TCP/IP, or Transmis- sion Control Protocol/Internet Protocol.
Hooked to the mainframe via the IBM Systems Network Architecture
(SNA) are: an IBM AS/400, which runs applications including that related to Workers' Compensation; 1,000 IBM PS/2 [R] personal computers; and seven IBM RISC System/6000 [R] processors running specialized optimization applications.
This was the problem faced by an installation in Turkey: Two protocols, the systems network architecture
(SNA) and IP--had to be supported.
SNA - or Systems Network Architecture
-has been a de facto data processing and networking industry standard for years, providing a popular alternative to the TCP/IP and Open Systems Interconnection (OSI) protocols.
