Messaging Accelerator (VMA)

Dramatically improves performance of socket based applications

Mellanox Messaging Accelerator (VMA) boosts the performance of message-based and streaming applications across a wide range of industries. These include the Financial Service market's High-Frequency Trading (HFT) platforms, Web2.0 clusters, and more. For Media and Entertainment broadcasting and streaming (supporting SMPTE 2110-21) please refer to Mellanox Rivermax.

VMA is an Open Source library project that exposes standard socket APIs with kernel-bypass architecture, enabling user-space networking for Multicast, UDP unicast and TCP streaming. VMA also features ease of use out-of-the-box, with built in preconfigured profiles such as for latency or streaming.
