WebSphere MQ Low Latency Messaging

Flexible message delivery options

• Transport high message volumes at rates of millions of messages per second for near instantaneous data transfer.
• Provide multicast messaging for high-speed, one-to-many communications through user datagram protocol (UDP).
• Offer point-to-point, unicast messaging using transmission control protocol over internet protocol (TCP/IP) to deliver data streams through a wide area network (WAN) or through a firewall.
• Use lightweight, point-to-point transport with positive or negative message acknowledgements.
• Support the latest technologies and standards, including 10 Gigabit Ethernet, InfiniBand and remote direct memory access (RDMA).

High performance and availability

• Provide automated stream failover for high system availability.
• Take advantage of services that detect failures, facilitate state synchronization of components and promote backup components automatically.
• Work with unique data packet methods and proprietary batching technology that adapt to throughput, message sizes, receiver and system feedback.
• Use wire-speed message persistence for recovery and auditing.
• Use shared memory for fast inter-process communication.

Message control and filtering

• Work with a range of message filtering options, including coarse-grained, topic-based and fine-grained label-based.
• Configure positive and negative message acknowledgements to manage varying degrees of reliable message delivery.
• Use multicast-by-unicast (MBU) transport to create a single topic once and send it to multiple physical destinations.
• Create topics to define and manage logical message streams and simplify topic provisioning.
• Take advantage of a message store that provides wire-speed message and event persistence.

System monitoring and congestion controls

• Report on message traffic rates to detect bottlenecks and regulate data flow.
• Analyze application and network statistics to monitor internal and external latency.
• Maintain performance levels dynamically, even as the complexity and volume of data increases.
• Monitor system service levels to protect the integrity of the data stream even when components fail.
• Detect and actively manage congestion using memory buffer usage limits and data transmission and retransmission limits with notification.

Standards-based integration tools

• Enable low-latency communication with other applications that perform associated, integrated functions such as trading, analytics and compliance.
• Integrate with IBM WebSphere DataPower® XM70 to support enterprise service bus (ESB) architectures in service-oriented architecture (SOA) environments.
• Use application programming interfaces (APIs) to monitor statistics and performance.
• Support a variety of platforms including Microsoft Windows, Red Hat Enterprise Linux, IBM zLinux, HP-UX Itanium and Oracle Solaris (SPARC and x86).
• Take advantage of a high-volume, low-latency messaging infrastructure that complements WebSphere MQ technology.
