What does your application or service do?
The creation of IRIS has been an impressive achievement at its launch, leading the company to be a finalist for the coveted Smithsonian Institution Award for Innovation in 1999. After years of improvements, IRIS is still leveraged to coordinate information used by employees and business applications across the entire company, tracking container movements and costs and more, dramatically enhancing operations’ efficiency".
What functionalities are powered by Lightstreamer?
"Within IRIS, mainly two kinds of data are pushed by Lightstreamer – (1) work tasks & notifications and (2) account receivable (AR) information.
(1) Work tasks and notifications are events generated by any module in IRIS system which have to be handled by our operators. The Dashboard (DSH) is a centralized task repository that collects elements from all IRIS modules. Work tasks and notification are distributed to our operators according to their competencies and skills, through a simple publish and subscribe mechanism. Relevant data are received by each individual dashboards, which shows assigned items (Module tasks > DSH > Lightstreamer > Operator).
Another web application is our invoice system, which receives (2) Account Receivable real-time data and updates web clients in real time. Account Receivable information are mostly invoicing-related information, such as customer payment instruction, charge, refund, tax, unallocated shipments, etc. Our invoice information updates volume is surprisingly large. These data updates could be over 40 per second in peak times, so unnecessary data is filtered before pushing data to browser based on user subscriptions item name.
In both cases, Lightstreamer data are pushed to our operators, mostly for customers’ service tasks. We have around one hundred users which are using web clients powered by Lightstreamer now. Their responsibility includes updating or checking the customer booking status - if some details, such as the payment method, need to be updated, we broadcast the real-time updates to all clients using Lightstreamer without refreshing the browsers and avoiding heavy network transfers."
Is your main application based on HTML or other front-end technologies?
What other features of Lightstreamer are you taking benefit from (e.g. data throttling, low latency, bandwidth management, security, smart proxy traversal, etc.)?
"We really appreciated the Lightstreamer StreamSense technology, which allows to choose the best transportation method for each individual client. This is very useful since WebSocket may be blocked by firewalls or be unsupported by older browser versions. For the same reason, we found the firewall and proxy traversal features of Lightstreamer extremely useful. In addition to this, Lightstreamer also provided many built-in controls which allow us to better manage the push behavior, such as flow control, buffer size control, snapshot, etc."
Why OOCL opted for Lightstreamer among many other products, both commercial and free?
"The real time data updating is really important for our operators. Now they can just open the page and wait for the tasks to be assigned, or notifications to be pushed, without refreshing the page. This aligns with their expectation and also improves their work efficiency. Furthermore, when we changed our application to thin client to enhance mobile support, our operators expected the new version to keep the same good efficiency as the legacy system. We adopted Lightstreamer to meet this requirement, considering that Lightstreamer can overcome the heavy network overheads switching to HTTP polling when needed. Lightstreamer accomplishes the needs of our operators and improved their work efficiency."
You integrated Lightstreamer within a huge message-oriented, distributed application like IRIS. How the Lightstreamer implementation process has gone?
"The first version of IRIS was written in GemStone/S Smalltalk, making it one of the largest Smalltalk applications in the world. The newer versions (which include Lightstreamer) are using Oracle DB and J2EE as technology, and we implemented it seamlessly. We started from a “Hello World” example provided by Lightstreamer itself, and then we built up our logic on top of it. With the help of API documents provided by Lightstreamer, we coded our adapter implementation smoothly within a short period of time."
Are you considering to extend your Lightstreamer usage? Are you planning to integrate Lightstreamer in other projects in the future?
"We are foreseeing more users receiving live data after we will integrate our new version of IRIS-4 to other regional offices. We have already upgraded our license to get unlimited update per second, and this is will make us ready for the upcoming Lightstreamer usage expansion."
We would be very grateful if you would like to provide a short recommendation to testify your experience with Lightstreamer technology and its support team.
"We found very easy to implement our own data handling logic by writing an IRIS-compatible adapter. We must say thanks to Lightstreamer support team for its helpful and rapid response during our implementation period. They provided many valuable suggestions and support to us including system load balancing strategy, SSL setup, etc."
