Analyzing communication flows on the network can help to improve the overall quality it provides to its users and allow the operators to detect abnormal patterns and react accordingly. In this paper we consider the analysis of large volumes of cellular communications records. We propose a method that detects abnormal communications events covering call data record volumes, comprising a country-level data set. We detect patterns by calculating a weighted average using a sliding window with a fixed period and correlate the results with actual events happening at that time. We are able to successfully detect several events using a data set provided by a mobile phone operator, and suggest examples of future usage of the outcome such as real time pattern detection and possible visualisation for mobile phone operators.

Analyzing and aggregating large-scale broadband measurements is essential to study trends and derive network analytics. These trends and analyses could be made available through well defined protocols such as the Application Layer Traffic Optimization (ALTO) protocol. However, ALTO requires network information to be distilled and abstracted in form of a network map and a cost map. We describe our methodology for analyzing the United States Federal Communication Commission’s (FCC) Measuring Broadband America (MBA) dataset to derive required topology and cost maps suitable for consumption by an ALTO server.

Content-Centric Networking (CCN) is a promising routing paradigm for content dissemination over a future Internet based on named data instead of named hosts. The CCN architecture has aspects that provide more scalability, security, collaborative and pervasive networking. However, several key components that secures the current Internet are still missing in CCN, in particular a firewall able to enforce security policies. We provide a comprehensive study of CCN security requirements from which we design the first CCN-compliant firewall, including syntax and definition of rules. In particular, based on CCN features, our firewall can filter packets according to both their authentication and the semantics of the content name. We also provide a performance evaluation of our prototype. [less ▲]

Content-Centric Networking (CCN) is one of the most promising research area for a future Internet. The goal is to obtain a more scalable, secure, collaborative Internet supporting context-aware services. However, as a new overlay infrastructure, CCN raises the need of a new monitoring architecture to assess security of CCN devices. In particular, the stateful nature of CCN routers introduces new attack threats that need to be addressed. We propose in this paper a monitoring approach for the instrumentation of CCN enabled network nodes. The rationale of our monitoring approach is demonstrated through real experimentations to detect and mitigate network level attacks against CCN. [less ▲]
