• 1-to-1 messages (to Customs)

September 2016

Maritime Single Window MSW

• 1-to-many messages

• Compliant by Design

• WCO Semantic model

• Dutch sea ports connected, incRotterdam

Generic Service

(e.g. WUS)

SMTP

• 10K bus messages per minute• 10 TIBCO nodes (BW, RV, EMS)• 30% burst

• No issues at burst• No issue with sustaining burst

POSTFIX

TERMINOLOGY• MSA – Mail Submission

Agent for mailclient to SMTP server

• MTA – Mail Transmission Agent for machine to machine SMTP traffic

• POSTFIX – Mail Server• WUS – WSDL, UDDI,

SOAP

TECHNICAL CHALLENGES:• Timelines• Burst traffic• 0 down time, 0 loss of

messages, 15s guaranteed delivery

What success looks like Mar 2016 Business

• Platform migration as-is

• Virtually no impact on businesses

• Customs Declarations

Lessons LearnedData synchronization is a problem

• DB data synchronization and latency (amount of data, pipe saturation, errors, etc)

Infrastructure fails

• Hardware fails, networks go down, KPIs not met, Hacks and attacks

Actively put in monitoring on day 1

• Don’t assume out of the box monitoring will meet your needs. Functional (individual component/service), Technical (middleware down) and E2E chain (message flow) need to be viewed in a consolidated place.

Equal partners, conflicting interests

• How to build trust and confidence

What success looks like next year?Tackling BREXIT

• 35,000 companies affected:

• More connected parties

• Message volume growth:

• B2G – 120, 000 MPD

• G2B – 60, 000 MPD

One Single Window to rule them all

• Interconnecting national Single Windows

• Additional: Tracking Cargo, Modes of transport and sharing Documentation

EU Single Window
