The importance of modern computer networks is steadily growing as increasing amounts of data are exchanged over company intranets and the Internet. Understanding current networking technologies and communication protocols that are available for the IBM® mainframe and System z® operating systems is essential for setting up your network infrastructure with IBM z/VSE®.

This IBM Redbooks® publication helps you install, tailor, and configure new networking options for z/VSE that are available with TCP/IP for VSE/ESA, IPv6/VSE, and Fast Path to Linux on System z (Linux Fast Path). We put a strong focus on network security and describe how the new OpenSSL-based SSL runtime component can be used to enhance the security of your business.

This IBM Redbooks publication extends the information that is provided in Security on IBM z/VSE, SG24-7691.

This book was produced by a team of specialists from around the world working at the IBM Development Laboratory in Boblingen, Germany and at the International Technical Support Organization, Poughkeepsie Center.

Joerg Schmidbauer is a z/VSE developer in the IBM Development Laboratory, Boblingen, Germany. He has worked for IBM since 1989 in VSE Development. In addition to z/VSE connector-related work, he works on z/VSE hardware cryptographic support. His latest project was porting OpenSSL to z/VSE.

Jeffrey Barnard is a Communications and Security Specialist and co-founder of Barnard Software, Inc. He has over 30 years of experience with z/VSE, communications software, and security. He is also one of the authors of IPv6/VSE and is well-known in the z/VSE community.

Ingo Franzki is part of the z/VSE Development Team at the IBM Development Laboratory, Boblingen, Germany. He joined IBM in 1997. His main focus is on z/VSE connectors, security, and performance. He is also consultant for solutions that involve distributed environments with z/VSE. Ingo is often a speaker at IBM events, user group meetings, and workshops.

Karsten Graul has worked in z/VSE development since 2000. His main work areas are the z/VSE connectors and Linux Fast Path. In recent years, he worked on the IBM z/VM® TCP/IP development team. Currently, Karsten is a member of the z/VSE TCP/IP team.

Don Stoever is a Senior Product Developer for CSI International in Columbus, OH and he brings 30 years of VSE systems programming, product development, and technical support experience. He has worked on the TCP/IP for VSE product since 1998 and now oversees its development and support.

Rene Trumpp is a z/VSE software engineer in the IBM Research and Development Laboratory, Boblingen, Germany. After joining IBM in 2006, he became an expert in System z networks. Besides implementing z/VSE SNMP support (z/VSE Monitoring Agent and z/VSE SNMP Trap Client) and the IBM z/VSE GDPS® Client, he also worked in the z/VM TCP/IP development team. Today, he is the key focal point for the z/VSE network device driver and part of the z/VSE TCP/IP team.
