NASDAQ transport protocols on the JVM

Nassau

Nassau implements NASDAQ transport protocols on the JVM.

You can use Nassau to connect to Nasdaq and other network endpoints that use NASDAQ transport protocols. You can also use it to provide your own services using these protocols.

Nassau is designed to exhibit low and predictable latency. To achieve this, it supports non-blocking, zero-copy networking and does not allocate any memory on message reception or transmission. The SoupBinTCP implementation can achieve 4.8 µs round-trip time (RTT) over the loopback interface.

Nassau requires Java Runtime Environment (JRE) 8 or newer.

Protocols

Nassau implements the following protocols:

• NASDAQ SoupBinTCP 3.00: a reliable transport protocol for applications requiring delivery of delimited, sequenced messages between two endpoints.

• NASDAQ MoldUDP64 1.00: a reliable transport protocol for applications requiring delivery of delimited, sequenced messages from one sender to many receivers.

• NASDAQ BinaryFILE 1.00: a file format for storing delimited messages.

Download

Modules

Nassau contains the following libraries:

• Core implements the NASDAQ transport protocols.

• Utilities contains utility methods for working with NASDAQ transport protocols.

Nassau contains the following applications:

• BinaryFILE Recorder records a MoldUDP64 or SoupBinTCP session to a BinaryFILE file.

• SoupBinTCP Gateway serves a MoldUDP64 session over the SoupBinTCP protocol.

Nassau contains the following example applications:

• SoupBinTCP Test Client implements a simple SoupBinTCP client.

Nassau contains the following test application:

• BinaryFILE Performance Test is a simple benchmark for the BinaryFILE implementation.
