MoreLess

• High messaging throughput and extremely low latency

• One-to-many multicast and point-to-point unicast messaging

• Support for User Datagram Protocol (UDP) and Transmission Control Protocol (TCP)

• Stream failover for high availability even when using commodity hardware

• Message traffic rate and congestion control

• A low latency message store for lightweight persistence

• Shared memory for inter-process communication

• A coordination manager for simplified topic provisioning

• Native InfiniBand support

• 10 GbE support

• Flexible, fine-grained message filtering

• Robust application and network statistics monitoring for internal and external latency

• Efficient market data distribution - Enables low latency communication to downstream applications that perform functions like trading, analytics and compliance. Congestion management software detects and actively manages congestion, offering memory buffer usage limits with notification; limits on data retransmission with notification; transmission rate limitation; and slow consumer policies.

• Reliable trade execution - Delivers highly reliable communication to the downstream execution infrastructure without performance degradation, with high availability and flexible message filtering for complex execution routing.

• Real-time market analytics - Offers robust message filtering to deliver relevant information to downstream applications that perform analytics and compliance.
