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 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.
Customer Managed Connectivity
Customer Managed Connectivity (CMC) provides customers with additional choice and flexibility, when directly accessing the London Stock Exchange Group. Utilising an optimised network infrastructure, engineered for low latency, resiliency and scalability, customers are able to access our markets through a number of Accredited Connectivity Partners.
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.
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.
