Data-hungry applications via the limited-capability satellite network

Transcription

1 Data-hungry applications via the limited-capability satellite network Maritime CIO Forum Rotterdam, 18 th Nov 2014 Ir. Peter Van de Venne Director IT, Spliethoff

2 Agenda - Bandwidth a precious commodity - Crew - How has traffic evolved? - revisited - Telephony - Virtual servers - Sensors - Conclusions - Future expectations

3 Total Fleet >100 vessels (about 15 persons/ship) Fleet

4 Always-on Internet - Reasons Crew: - Private (gmail, msn, ) - Chatting with home/friends - Electronic banking - Home newspapers - Surfing Crew Business IT Business: IT: - Communication between ship/shore accelerated - Downloading manuals - Port details, Cargo details - Water heights - Weather and ice charts - Less printing of private -Supporting captain with PC problems -Remote install of updated software

5 Bandwidth a precious commodity - Substantial bandwidth cost (airtime + initial cost) Compression - Discussions on what crew contribution would be fair and how to enforce it. - Some crew members ate all bandwidth, leaving nothing for their collegues Organize charging Organize fair distribution Middleware

6 VSAT setup Antenna control unit idirect satellite modem Patch panel Ethernet switch INFINITY BOX UPS power Circuit breakers Ventilation

7 Crew Policy Internet Get 300 MB/month free allowance (equals about 600 MB before compression) 0.20 USD/MB above 300 MB allowance Buy USD (from leisure of their cabins) (infinitely valid) Bring Your Own Device (no company provided PC s) No further restrictions (skype, etc ok) (as long as legal) Friendly hints for controlling data usage Unlimited internet access on special projects (waiting hours)

8 Crew: Infinity dashboard The user can open the firewall on demand Simulate a mobile device (less bandwidth)

9 Crew change integration How to get crew changes automagically to ship? Webservices: - RegisterUser( ) - Signoff(UserID) - BuyCreditsFromShip(UserID,nn USD) No extra work for captain. Crew can buy extra (never expires) Fair Charging based on free monthly + additional buy on board (never expires)

11 VSAT monthly total cost 2,500 2,000 1,500 1, Total cost/vessel 15-Dec-13 Monthly airtime Monthly infinity Crew returns/month/ship Repair (estimate) 0 O5 oct Dec-13 Write off of investments Less phone calling cost (business VoIP) -Cost has gone up, but bandwidth has gone up from 23 to 256 kbps CIR! -Crew revenues pay for the infinity box

12 Crew vs Business Snapshot from Infinity interface 83% Crew 17% Business

13 Business - Crew How do we make sure the business doesn t drown in crew traffic? Quality of Service (QoS) : QoS, order (most important first): VLAN IP Range Ports Description xxx.0/24 VoIP xxx.0/24 Sensor xxx.0/24 Business TCP RDP/VNC : Remote Access, shore>ship TCP SQL TCP HTTP/HTTPS TCP POP/SMTP TCP 21 - FTP - All other xxx.0/24 Crew xxx.0/24 Tutor (students) Implemented in the Infinity Box

14 Compression Netto 2.2 => 256 kbps feels like 512 kbps Compression in reality even better: + Advertisement reduction + Local http caching + Local DNS caching Snapshot from Infinity interface

15 Uplink - Downlink Average Up/Down 22% 78% Uplink Downlink Uplink Downlink kbps kbps Original situation (symmetrical) Current situation Next step?

16 revisited Via VSAT cost is peanuts Via backup FBB/IOP still costly => direct mail with more intelligent control needed Notifications: Your message has been delivered >5 MB => Your message has NOT been delivered (rejected) Your mail has been put on hold until the connection is restored (max 5 days). The internet connection has been out of service for more than 5 days => discarded

17 Telephony (VoIP) Office staff and vessels can call each other internally (4-digit number) Increases cohesion between office and fleet Free of charge The quality of the voice is very good Phones can be placed anywhere on the vessel s network Technical notes: - SIP connection between office Mitel PBX and Infinity VoIP - Siemens DECT VoIP phones on the vessel - Separate Voice VLAN

18 Virtualization Environment Infinity Virtual machines: VSAT provider can remotely support the ship s satellite systems Virtual vessel PC (planned) Centralised Database Server Centralised Web/Application Server

19 Sensors Sensors currently connected : - Fuel flow (IFO, MDO, Boiler) - Torque (propulsion power, shaft generator) - GPS (position + speed over ground + direction) - Speedlog (speed through water) - Wind meter - Crane control (Huisman; via sensor VLAN) Standard interfaces? NMEA, pulse, Volt, Ampere, modbus, Big Data : datalogger reduced from 1x/min to 1x/15 min; still a lot of data Not online, but via MS SQL database sync Combined with weather routing (Meteo Group SPOS)

20 Conclusions 1) Crew : fair distribution + charging + administration in place 2) Average traffic has increased from 8 to 22 GB 3) Compression makes 256 kbps feel like 512 kbps 4) QoS makes sure that 17% Business doesn t drown in 83% Crew traffic 5) Direct now possible, including sophisticated control 6) Telephony brings fleet and office closer together 7) Sensor LAN now actively used

21 Future Expand always-on Internet to 22 more vessels (128/256 or 128/384) Hunger for more bandwidth will remain Shift from infrastructure to applications: web-based (on-board) applications (vessel cloud + sync to office) fuel saving (interpreting sensor data) renewed arrival/departure/noon/bunker apps (no longer messages) incident reporting app (solving large file attachment sync challenge) how to mix map layers: private company info+weather+ecdis? ECDIS directly connected to sensor VLAN Video (tele-medicine + tele-maintenance)
