Performance channels

Performance Channels are high speed delivery mechanisms that increase the rate at which data can be sent out to the market.

Performance Channels are of particular benefit to customers who need to have the lowest latency connectivity to the Exchange during peak trading periods. The service offers a reduced latency, high speed delivery mechanism, which increases the throttles that are necessary on Service Channels to provide a managed service.

Performance Channels will also have a new liquidity aligned structure for the UK data channels, to increase the efficiency of market data delivery and optimise the way in which messages are distributed across channels.

Throttling policy

The Exchange’s current Service Channel throttling policy protects customers’ connections and systems from high volumes of data overflowing their Extranex connection. This can mean that during extremely busy periods Service Channels can be subject to minor latency as the high volume of messages being disseminated are “throttled” back in order to protect customer systems and networks from these high data spikes.

Although these high data spikes in Infolect real-time data are relatively infrequent, they can result during times of high trading activity. Performance Channels effectively remove the throttles by increasing the available bandwidth for the data to ensure it is disseminated as it arrives - unshaped.

To receive the service customers will need to have ordered and migrated to an Extranex 100mb connection.

The full Performance Channels service was launched on 9 June 2008.
