The Whisperer Enterprise interface is founded on the Simple Binary Encoding (SBE) protocol which was commissioned by the CME in 2013, and has become the de facto successor to FIX / FAST.
Martin Thompson of Real Logic Ltd. describes the SBE reference implementation as "a compiler that takes a message schema as input and then generates language specific stubs. The stubs are used to directly encode and decode messages from buffers. The SBE tool can also generate a binary representation of the schema that can be used for the on-the-fly decoding of messages in a dynamic environment, such as for a log viewer or network sniffer."
This is a clean-start development, allowing MarketFactory and its customers to move to a new integration model, as outlined below. Whisperer Enterprise is not related to the Whisperer Classic SBE3 implementation in any way and utilises a completely new SBE schema and Server-side components. Whisperer Enterprise differs from Classic in that there is no API server. Instead all client connections are arbitrated by a single Logon Service that hands-off the connection to the relevant Feed Handler, which then communicates directly with the client thereafter for all session types. For detailed information relating to the changes, please refer to Whisperer Enterprise vs Whisperer Classic. |
As with our previous SBE offering, MarketFactory provides a reference client implementation in Java, using a Zero-GC, single threaded implementation model. This is based on the the SBE reference sources and illustrates the end result of using the the Real Logic compiler against the Whisperer Direct SBE Schema to generate compilable codec stubs and integrating the generated code with a higher level interface that supports the desired pricing and trading workflows.
Equivalent steps may be adopted for for C++ or .NET (as preferred),
The Whisperer Enterprise implementation employs the latest Simple Binary Encoding - version="1.0 Draft Standard" This is NOT the same as that utilised for SBE3. |
