Service composition is an aggregate of services often leveraged to automate the enterprise business processes. While Service Oriented Architecture (SOA) has been a forefront of service composition, services can be realized as efficient distributed and parallel constructs such as MapReduce, which are not typically exploited in service composition. With the advent of Software-Defined Networking (SDN),...
Random Linear Network coding (RLNC) has emerged as a promising solution for reliable multimedia delivery over mobile cellular networks. In this paper, we deploy Application Layer-RLNC (AL-RLNC) on the top of the existing Hybrid Automatic Repeat Request (HARQ) in 4G Long Term Evolution (LTE) networks. A simple implementation scenario composed of a user equipment, an eNB and a remote host is considered...
Telecom sector is in the middle of a global transformation. Drivers for this are changes in customer behavior and in the telecom industry itself. Today CSPs need a more sophisticated, real-time view of performance that provides a deeper understanding of how customers are using and experiencing specific services. Moving from network-centric toward customer-centric operations and introduction of Customer...
The advent of the Big Data era and the diffusion of the Cloud computing paradigm have renewed the interest in Data Stream Processing (DSP) applications, which can timely extract valuable information from an increasing number of data sources (e.g., sensing devices, social networks). The distribution of data sources, the huge and unpredictable volumes of produced data, and the diffusion of heterogeneous...
We are facing an increasing interest about virtualization technologies that enable new paradigms and technical approaches like Cloud Computing, Software Defined Networks. Infrastructure Providers (InPs), managing distributed physical resources, need to perform the mapping of the requested virtual resources on the physical ones. For this purpose, they need to optimize the allocation process in order...
