Building the order gateway server

In this section, we will start building the order gateway server infrastructure, which is responsible for setting up a TCP server for clients to connect to. The order gateway server also needs to process incoming client requests from different clients in the order in which they arrive and forward those to the matching engine. Finally, it also needs to receive the order responses from the matching engine and forward them to the correct TCP connection for the corresponding market participant. We will revisit the design of the order gateway server and how it interacts with the matching engine and the market participants, as follows.

Figure 7.1 – Order gateway server and its subcomponents

To refresh your memory, the order gateway server receives new TCP connections or client requests on established TCP connections. Then, those requests go through a FIFO sequencer stage to make sure that requests are processed in the...
