Product Overview

The architecture of TCP/IP for VSE centers around a core TCP/IP stack that provides the foundation for network communication on zVSE/VSEn systems. Key components include the TCP/IP stack itself, responsible for handling TCP/IP protocols; the FTP server, which allows for file transfer using the FTP protocol (commands like `FTP `); the TN3270 server, providing terminal emulation services; and the HTTP server, enabling web services. These components communicate using standard TCP/IP protocols, with the TCP/IP stack managing routing and data transmission.

APIs are available for COBOL, PL/1, C, Assembler, and REXX, allowing applications to interact directly with the TCP/IP stack. Configuration is primarily managed through configuration files accessed via a command-line interface (CLI). Security features include username/password authentication and potential integration with external security systems like LDAP.

Competing products offer similar architectural components, but TCP/IP for VSE's specific API support and integration with VSE security are key differentiators. Monitoring and logging capabilities provide insights into network traffic and system events.

Frequently Asked Questions

What standard TCP/IP services are included?

TCP/IP for VSE provides standard TCP/IP services such as FTP for file transfer, TN3270 for terminal emulation, and an HTTP server for web services. It also supports email protocols like SMTP and POP3.

What programming languages are supported for TCP/IP access?

The product includes APIs for COBOL, PL/1, C, Assembler, and REXX, allowing applications written in these languages to directly utilize TCP/IP functions. These APIs enable tasks such as creating sockets, sending and receiving data, and managing network connections.

What are the main system components?

Key components include the TCP/IP stack itself, the TN3270 server, the FTP server, and the HTTP server. These components work together to provide comprehensive network services.

What authentication methods are supported?

TCP/IP for VSE supports authentication methods such as username/password authentication for services like FTP and Telnet. It may also integrate with external security systems for enhanced authentication capabilities.
