IBM upgrades WebSphere MQ Low Latency Messaging

05 May 2009  |  2610 views  |  0 Source: IBM

IBM WebSphere MQ Low Latency Messaging is a messaging transport that is highly optimized for the very high-volume, low-latency requirements of Financial Markets firms.

Applications include the high-speed delivery of market data, transactional data, reference data, and event data in or between front-, middle-, and back-office. Although initially designed to meet the high-speed and throughput requirements of financial services firms, WebSphere MQ Low Latency Messaging is suitable for use by other industries with similar requirements. Characteristic applications require extremely low (submillisecond) latency and high message volumes (ranging from many thousands to millions of messages per second), with positive or negative acknowledgement reliability, but not requiring the assured delivery provided by WebSphere MQ. New high availability function through Reliable and Consistent Message Streaming (RCMS) features can make WebSphere MQ Low Latency Messaging a very attractive solution for exchanges and other firms that need to send large message volumes with high availability and reliability in a tiered, replicated environment. Version 2.2 adds the following enhancements to existing capabilities:
• Lightweight Message Store
• Shared memory for inter-process communication
• Reliable Unicast Messaging Enhancements
• Multicast by unicast and hybrid topics
• Enhanced High Availability Features
• RCMS on Unicast over Reliable UDP with support for Multi-Site Failover
• Expanded platform support: 64-bit zLinux and HP-UX on RMM
• Internet Protocol version 6 (IPv6) support
• Usability enhancements
