Feed handlers manage data that arrives
directly from an exchange, like the NYSE, or a consolidated service
provider, like Reuters. Using the publisher API, the feed handlers then send the data over the network to one or more subscribers.
Publisher API
RAP includes a publisher API library, which is used by feed handlers to format incoming market data, and send data to subscribers by user datagram protocol (UDP) multicasting.
FAST Feed Handler
The FIX Adapted for Streaming (FAST) protocol is an emerging standard defined by the FIX Protocol, Ltd. as a method of compressing messages to be exchanged over a network connection.
Demo Feed Handler
The demo feed handler demonstrates network message flow and is intended to familiarize developers with the publisher API.
