The objective of the symposium is to identify new approaches for the optimization of tests of safety-critical, software-based railway systems. The complexity of such systems in the railway sector as well as specific requirements related to safety and availability require an enormous effort for test and commissioning today.

How do those methods improve testing by reducing the effort or increasing the error detection rate? How do they need to be adapted to be used optimally in the railway sector?

Is Big Data only a marketing hype?

Big Data is often used as a trending buzz word for marketing purposes. However, the Big Data struggle for mobile network operators is very real. Operators are sitting on petabytes of data not knowing how to handle or monetize all the information available in their network. When building a Big Data solution, important marketing questions are raised in order to build an effective and efficient solution:


So what is Big Data?

Big Data refers to the large set of technologies encountered when dealing with very large volumes of data. The technologies employed to tackle Big Data are obviously databases but it is also the capacity to extract and process large (but not always) volumes of data, correlating data coming from heterogeneous sources, making predictive analysis, the capability to move data from one place to another, building meaningful analytics while providing results to users in a usable way.


Is it hard to implement?

Already complicated to implement, it becomes even more tricky when constraints such as an open, real-time and low-cost solution are necessary for an Operator. An open big data architecture is a critical choice as it assures the operators with a future-proof and cost-effective platform in case of evolution, upgrades or swap.

Dealing with the Big Data paradigm requires solution providers to manage numerous technologies. But it also requires marketers to have the skills to understand the customers’ needs as there is no single solution fitting all needs. Use cases are a meaningful way to try to describe some of the customers’ needs in a more precise way.


Why Big Data for Network Data Mining?

To see the big picture. Operators’ are today equipped with multiple solutions from multiple providers, using multiple databases and technologies. The next big thing in the operator’s monitoring solutions is to make sense of all the data available by correlating multiple sources on a big scale to provide unequaled insights enabling the operators to enhance their network and to make better strategic decisions.

When considering the classical 3 Vs –Volume, Variety and Velocity– of Big Data in a network data mining perspective, it means processing billions of transactions generated by the network elements and subscribers per day.

This data comes from very different sources: network elements, probes from different vendors, CRM databases from the Customer Care department and more. An efficient network data mining solution must be able to correlate rapidly these different sources and provide results in real-time as subscribers wants their technical issues to be solved as fast as possible.

Big Data technologies go further by providing tools and techniques and processing that were before unthinkable and now possible. Below are examples showing how Big Data solution can offer new techniques to detect suspicious network events or behaviors.


Example of a complex analysis

Spam is becoming more and more intrusive and operators want to protect their customers from unexpected SMS or calls. One new scenario is called indirect ping call and refers to cases where a spammer send an SMS to a subscriber containing a message mentioning a number to be recalled. This number is often a heavily-taxed number. Detecting automatically this scenario is impossible using standard SQL queries as it involves a sequence of transactions. It is also mandatory to quickly track the change of spammers’ strategy so that it must be implemented in a way that rules are easily changed according to evolutions. That is a case where Big Data based analysis allows new detection and analysis that are not possible with standard solutions.


Example of an unpredictable event

Expandium has once seen an SCTP packet, a signaling data unit exchanged between 2 equipment, doing a ping-pong between 2 SS7 STPs as the routing tables in one of the equipment was misconfigured. This “issue” generated 5,000 messages per seconds. This may sound low considering a network dealing millions of such packet per seconds, but imagine if hundreds of such packet occurred. That raised immediately a big alarm for people in charge of the network security. Are your monitoring systems able to detect these kind of issues? If you are not aware that such incidents can happen, there is a big chance that you cannot detect it. On the other hand, if you know it can exist, it is very easy to implement a KPI that will detect the next time it happens.

The tricky part is to be able to detect an incident without knowing that such an incident even exists. And technologies moving around big data enables this, taking advantage of quantities of metrics available and running predictive analysis on those.
