Mainframe networking involves a complicated set of technologies and disciplines that require specialized knowledge. At BCL, we help organizations maintain high availability and secure connectivity across complex enterprise environments.
From legacy protocols like VTAM and NCP to modern TCP/IP-based communication, our team supports the systems that keep your enterprise server connected and responsive.
Mainframe networking refers to the combination of hardware, protocols, and software required to ensure secure and consistent access to mainframe systems. While legacy protocols such as SNA, VTAM, and NCP continue to play a role, TCP/IP has become equally essential for connecting modern applications, users, and partners to enterprise servers.
In the System z environment, TCP/IP includes a wide range of tools and services, such as the TCP/IP stack, FTP, TELNET, and TN3270. In more recent versions of System z, the TCP/IP stack is integrated with UNIX System Services, adding flexibility and performance.
Common uses of mainframe networking supported by BCL include:
We have implemented networking solutions for a wide range of client environments. One of our main goals is to help organizations improve availability and performance while minimizing complexity.
BCL supports all major components of mainframe networking, including:
Flawless availability is expected across all enterprise network connections. Network outages, configuration issues, or protocol mismatches can interrupt essential business operations.
Mainframe networking requires coordination across tools, protocols, and environments that were once handled by separate specialty teams. We handle it all in one place so there is less chaos and more organization
BCL brings the cross-discipline knowledge of z/OS, CICS, TSO, VTAM, TCP/IP, and NCP into a unified support team to help clients maintain stable, scalable connectivity.
