CA NetCompress Modernization Guide

CA NetCompress is a software product designed to reduce the bandwidth required by 3270-based applications. It achieves this by compressing 3270 data streams, making data transmission more efficient.

CA NetCompress is a system-level software product that operates transparently between 3270 applications and the network. It is not an application in itself, but rather middleware that optimizes data transmission.

Organizations that rely heavily on 3270 applications and need to optimize network bandwidth usage are ideal candidates for CA NetCompress. This includes businesses in finance, insurance, and other sectors with significant mainframe-based workloads.

A company should consider CA NetCompress when they experience network congestion due to 3270 traffic, or when they want to reduce the cost of network bandwidth for mainframe applications. It is also useful when migrating or extending 3270 applications.

Alternatives to CA NetCompress include other network compression products and hardware-based compression solutions. Some examples are IBM Communications Server and various network optimization appliances.

CA NetCompress runs on the z/OS platform. It typically operates within an LPAR and is dependent on z/OS subsystems for its operation.

CA NetCompress requires a z/OS environment with the necessary network infrastructure to support 3270 applications. It integrates with VTAM for network communication.

The main components of CA NetCompress include the compression engine, the decompression engine, and the control components that manage the compression process. These components work together to optimize 3270 data streams.

CA NetCompress uses configuration files to define compression parameters and network settings. These files are typically managed by system administrators.

CA NetCompress reduces network bandwidth consumption, leading to lower network costs. It also improves the performance of 3270 applications, enhancing user experience.

By optimizing network traffic, CA NetCompress can help organizations avoid costly network upgrades. It also extends the life of existing network infrastructure.

CA NetCompress integrates transparently with existing 3270 applications, minimizing disruption to business operations. It does not require changes to application code.

CA NetCompress supports standard authentication methods available in z/OS, such as RACF, ACF2, and Top Secret. It leverages these security systems for user authentication and authorization.

CA NetCompress uses an access control model based on z/OS security systems. Access to configuration and management functions is controlled through RACF or similar security products.

CA NetCompress can encrypt data streams to protect sensitive information during transmission. The specific encryption algorithms used may vary depending on the configuration.

CA NetCompress provides audit logging capabilities to track configuration changes and access attempts. These logs can be used for security monitoring and compliance purposes.

CA NetCompress is typically deployed on-premise within the z/OS environment. It requires system programmers with expertise in z/OS and network configuration for implementation.

Ongoing operational requirements include monitoring the performance of CA NetCompress, maintaining configuration files, and ensuring compatibility with other z/OS subsystems.

Common implementation challenges include configuring CA NetCompress to work seamlessly with existing network infrastructure and resolving compatibility issues with other z/OS software.
