DB2 and network communication

The DB2® data server products can communicate by using both wide area networks (WANs) and local area networks (LANs).

WAN

A wide area network generally supports the enterprise servers such as DB2 for z/OS®; they require either Transmission Control Protocol/Internet Protocol (TCP/IP) or Systems Network Architecture (SNA).

LAN

A local area network generally supports smaller servers, which requires TCP/IP.
