Connectivity

Connecting to the Exchange
The Exchange currently offers several types of connectivity with varying levels of management and performance. These range from a full host-to-host solution to a Vendor Access Network connection, as described below.

• Exchange Hosting
  Exchange Hosting is the London Stock Exchange’s lowest latency connectivity option for firms looking to gain the fastest access to the Group’s markets. Trading participants, information vendors and solution providers locate their servers physically within the Exchange’s own data centre, providing ultra low microsecond access to our trading matching engines and real-time market data.

• Extranex
  Customers with their own trading and information systems can connect directly to the Exchange via Extranex. Extranex provides customers of the Exchange with dedicated point to point connections for market data and trading. Extranex is fully supported by the Exchange, providing the highest reliability connectivity.
  
  Extranex provides a single point of access to support a wide number of trading and market data services. Lines can be sized to suit the information and trading service requirements of the firm. The scalability of Extranex allows information services to be added as required.

• Network Service Providers (NSPs)
  The Exchange has extended its network reach globally by partnering with accredited network partners. NSPs act as carriers of Exchange information and trading services to its end clients, who contract with the NSP for provision of network connectivity and sign agreements directly with the Exchange for access to trading and information. Customers of NSPs will have service enablements set up on the Exchange’s trading and information systems in exactly the same way as a direct Extranex customer. The data and trading feeds are in exactly the same format as those received by a direct Extranex customer and are subject to the same testing requirements

• Vendor Access Network (VAN)
  Through it's Vendor Access Network model, the London Stock Exchange works in partnership with vendors who have met its accreditation requirements to provide access to the Exchange's trading system via their proprietary networks.
