US 2012/0259761 A1 · Low Latency Financial Data Network Architecture

Abstract

A financial market data network having a lowered overall latency includes communication interfaces, specialized switches having internal switching fabric, and feed handlers that all facilitate communications between financial exchanges and consumers of financial market data therefrom. A feed handler is situated within or proximate a specialized switch and is arranged to receive raw financial market data directly from financial exchanges without the data first traveling through any switching fabric. The feed handler is adapted to process the received raw financial market data into a normalized format before the normalized financial market data is ever routed through any switching fabric, prior to being sent to consumers. The communication interfaces can include I/O ports located on the specialized switches, and the feed handlers can include one or more computer processors or servers. Additional internal switch components can include packet processors and storage components that store network protocols and/or layer tables.

Dependent claims

A financial market data network, comprising:

one or more initial communication interfaces adapted to facilitate communications between the network and one or more external financial exchanges that provide raw financial market data;
one or more secondary communication interfaces adapted to facilitate communications between the network and one or more external consumers of the raw financial market data provided by the one or more external financial exchanges;
at least one specialized switch situated between at least one of the initial communication interfaces and at least one of the secondary communication interfaces, wherein said at least one specialized switch includes switching fabric that is adapted to facilitate communications between the one or more external financial exchanges and the one or more external consumers;
and
at least one feed handler situated within or proximate said at least one specialized switch and arranged to receive raw financial market data directly from the one or more external financial exchanges without the received raw financial market data first traveling through any of the switching fabric, wherein said at least one feed handler is adapted to process the received raw financial market data into a normalized format before the financial market data is sent to the one or more external consumers.

2 more elements

A method of providing communications over a financial market data network, the method comprising:

receiving a raw financial market data feed directly from an external financial exchange without the raw financial market data feed first traveling through any switching fabric;
processing data from the raw financial market data feed into a normalized format before the financial market data is sent through any switching fabric, wherein the normalized financial market data is suitable for use by one or more external consumers without further processing of the financial market data;
routing the normalized financial market data through a switching fabric after said processing step;
and
delivering the normalized financial market data to the one or more external consumers.
