Who is communicating with whom in my network?
TUM and Infosim® PoC
Demonstrated live at SIGCOMM’19 held in Beijing, the PoC showed a system that uses Stochastic Block Models (SBMs) to infer structural roles of hosts and communication patterns of services in networks. The system, called NOracle, can be used with StableNet® to analyze and visualize networks in an online manner or it can be used to analyze stored traces. Network operators can use SBMs to monitor and verify network operation, detect possible security issues and change-points. To showcase this, NOracle combines StableNet® with an SBM based anomaly detection and network visualization module. StableNet® provides network flow statistics in real-time from actual devices. The SBM extracts roles and communication patterns live from the data provided by StableNet®. The result can help to reason about communication behaviors, detect anomalous hosts and indicate changes in the large scale-structure of network communication.
Data is taken live from the enterprise network testbed located at Infosim’s HQ. The enterprise network provides a testbed for trying out network management operations — it consists of more than 100 devices. StableNet® is the core part “glueing” everything together, i.e., it fetches networking data from all devices and makes it available. The demo showed how a network operator can inspect the communication behavior of the users and services live at run-time. Using NOracle’s GUI, a network operator/administrator can investigate the evolution of the network over time, or investigate details of the communication structures within or between groups. Clients that should be blocked from the outside world should not show any communication with “external” groups. In the end, human knowledge is useful or even required to finally infer the semantic meaning of the communication groups.

Platforms and Workflows that Automate Operations
Without any doubt, multi-faceted automation tasks cannot be uniformally covered with a “one size fits it all” solution. In other words, each firm must establish focused priorities and functional compromises in order to develop the foundation for a successful network automation solution.
Who is our competitor? The view from our CEO of N. American Operations
We face three primary types of competition, for various possible customers in the NMS arena. The customer types range from enterprises that need to secure the health of their network for production purposes to Telcos that require service assurance for the network services that they provide to their clients, and anything in-between.
Marketing at Infosim – An interview with our Director of Marketing
As it has been nearly a year since Dr. David Toumajian first joined Infosim® as the Director of Marketing, we wanted to ask him a few questions about his experience at the company and some of the key initiatives that the marketing department has been working on during that time.
