Gateway Options

Service Overview

The Data Transfer Service (DTS) provides a managed file transfer service. Files contain one or more information ‘flows’, such as meter reading information in a standard logical format. The DTS provides a local connection to the User’s internal network through Gateway Servers. These Gateways provide the interface to the DTS network (DTN).

Here is a high level diagram showing how users with different Gateway types connect to the DTS.

sa-diagramThere are currently six types of Gateway connection:

1) Remote User Gateway (RUG) – This is a remote server on which you will be allocated a dedicated Host directory (with a number of default sub-directories), through which you will send and receive flows via the DTS.

The majority of our users start with this option and can upgrade to any of the other connections below should their data usage and volumes increase. Users connect to the RUG via the Internet using dedicated Cisco software which can be installed on a PC or a Server. This is also the quickest to set up.

2) Low Volume Gateway (LVG) – This Gateway is connected to the DTS through dedicated communications lines, and offering a 1mbps bandwidth. Normally housed at your site in a rack provided by ElectraLink, the Gateway can instead be installed in one of your own racks, if this is required.

3) High Volume Gateway (HVG) – This is the same as the Low Volume Gateway, except that it has a 2mbps bandwidth link and will transfer higher amounts of data than the LVG.

4) Virtual Low Volume Gateway (VLVG) – This option utilises two network connections in the same configuration as the Low Volume Gateway, i.e. a primary 1mbps MPLS connection with a backup connection in case the MPLS fails. Users of this option connect to a shared, virtual Gateway server at the central hub, which is partitioned between all virtual users.

5) Virtual High Volume Gateway (VHVG) – This is the same as the VLVG above, but utilises two network connections in the same configuration as the High Volume Gateway, i.e. a primary 2Mbps MPLS connection.

6) Remote Virtual Gateway Options (RVHVG and RVLVG) – For those large users who wish to operate their DTS connection across the public Internet instead of through a dedicated MPLS and backup circuit, ElectraLink can provide Remote Virtual Gateway options. These operate in a similar way to the Remote User Gateway. However, they provide dedicated Internet bandwidth for each user at the central data centres, rather than the existing RUG arrangement which shares a single link for all RUG users.

Connecting to the Remote User Gateway (RUG)

The Remote User Gateway is the most commonly used connection to the DTS by customers. Connections to the RUG can be made in one of two ways:-

1) Cisco AnyConnect Client Software– Cisco software is used to provide a secure connection to your Remote User Gateway using the internet. This installs (to your PC) directly from the main VPN Concentrator (Firewall Device) via a link provided by ElectraLink. This does not usually require Firewalls rules setting up and uses standard Secure Socket Layer (SSL) ports which are normally open on internet browsers.Good for smaller companies who do not send out large number of files. A short video on how to install this is available online.

2) Site-to-Site VPN – This option allows customer networks to connect to the DTS. Customers are expected to make configuration changes to their Firewalls or other network entry devices as part of the set-up. Please note that ElectraLink does not provide this as a default connection option. Existing or new RUG Customers wishing to use this connection option will be asked to cover the one off set up charges.
