Data Switch

This system has  developed a modular, scalable and customizable marine data routing solution that meets the needs of shore-based and vessel-based users.

Is a MS-Windows software solution that connects nodes (hardware sensors, users, and/or networks) and chooses the optimalway to send each information packet based on its current understanding of the nodes. DataSwitch performs a number of functions when data is passed into it; unlike hardware routers found on the internet that simply pass information from one network device to another. DataSwitch can filter data as it is received, and does not necessarily forward all received information.

For shore-based networks, enables the flow of information from one or more AIS base stations and/or receivers to a Vessel Traffic Services (VTS) centre. Similarly, a VTS centre can send vital information to a regional headquarters, and then on to a national entity via another . For a vessel-based network, can send information from attached NMEA devices (sensors) to a number of stations on the vessel. The distribution of both standard and proprietary data messages from one central location to shared locations, makes essential in many diverse environments.

Features & Functionality

  • DataSwitch provides a reliable flow of information to your environment that is flexible and highly configurable.
  • DataSwitch allows multiple sources of standard and proprietary data to be collected, filtered, sorted, and securely redistributed according to defined rules and user rights.
  • Networks can configure DataSwitch to accept or reject certain messages, and it can be configured to distribute information as it is needed by any network.
  • DataSwitch is node based (hardware sensors, users, and/or networks) and provides a way to easily manage the stream of data between nodes. A node can be both a source and a destination for information.
  • Two separate nodes, however, are required to transfer data. Currently, DataSwitch accepts NMEA 0183 sentences, but ICAN offers complete customization support for additional message formats, including proprietary messages. Sentences can be collected from several sources, using: RS-232 serial ports; TCP ports; UDP ports; and from files on a computer’s hard drive. This information can also be logged to a local log file or database for future playback.
  • Data is collected and then managed by creating a user list, with each node allowed to receive (or transfer) an allowable set of standard or proprietary sentences. In this way, each node can provide (or accept) various sentences. As an example, DataSwitch can be configured to read certain sentences from an RS-232 serial port. A user can then be configured to receive a (sub) set of the incoming sentences from the RS-232 serial port user.
Optional Modules
Standard Communications– Handles two-way communications as well as connection control. (This module is required for all other modules listed below).

Enhanced Communications – Adds advanced connection protocols that are an extension to the normal use of DataSwitch. For example,customers can use UDP and Proprietary connections.

Secure Communications – Offers the ability to encrypt and decrypt AIS messages in order for non-secure client systems to participate in a secure AIS network.

Data Conversion – Offers customers the ability to convert incoming data to a particular data format.

Enhanced Control Monitoring – Allows DataSwitch to participate in a redundant configuration, significantly minimizing the risk of data loss

Filtering – Option 1 – Includes filtering based on duplicate messages, NMEA messages types and connections.

Filtering – Option 2 – Includes filtering based on AIS message, geographical area, and vessel parameters (i.e. MMSI number, IMO number,Call Sign, Ship Name, and Navigational Status).
