MEFFAccess (Controlador de comunicaciones)

MEFFAccess is a communications controller supplied by MEFF that performs market proxy functions. It stores the information received from the exchange and supplies it to the devices connected to it. It takes information from connected devices and delivers it to the exchange.

- MEFFAccess centralises access to MEFF -

Due to its function, and the fact that it is directly connected to the exchange, MEFFAccess-enabled hardware is always located in the vicinity of the network administered by MEFF. This further facilitates software upgrades or any required intervention by MEFF.

MEFFAccess establishes a TCP/IP connection with the access nodes through which it in turn accesses the central systems. MEFFAccess maintains a list of access nodes for each service, each with a preferred associated connection. This list is configured by MEFF to best suit the member.

MEFFAccess is configured to detect connectivity problems at its main access node and to move on to the next access node on the list. Once communications with the main access node are reestablished, MEFFAccess connects back up via this node.

- MEFFAccess detects and manages exchange access problems -

MEFF installs two or more MEFFAccess servers in each member's network thereby guaranteeing that each device is connected to a minimum of two servers. If a device's primary MEFFAccess connection fails, the terminal redirects orders to its back-up MEFFAccess server. This process is transparent to users.

- Automatic selection of MEFFAccess server in an emergency -

MEFF configures its MEFFAccess servers so that they are all used, distributing data traffic across the customer's hardware.

When a computer connects to MEFFAccess, the latter updates the computer with the current market situation. Locating MEFFAccess midway between the exchange and the devices it services enables speedier synchronisation, as this process takes place within the local area network.

As a general rule, MEFFAccess only receives public exchange data and data on the member that it belongs to. Notwithstanding, a single MEFFAccess server can be used to provide service to more than one member.
