In the latest years, we have seen a fast evolution of Internet systems and a remarkable increase of the number and variety of services required. The need of new architectural solutions has led to the creation of new tools that allow to develop more flexible and dynamic networks. Software Defined Networking (SDN) goes in this direction, offering a new way to manage networks, based on programmability,...
In this article, we discuss trends, issues, requirements and solutions for customer service assurance (CSA) platforms for mobile broadband networks. We propose a distributed probe-based architecture called intelligent CSA (iCSA), and demonstrate how it is a key component of an advanced OSS. iCSA provides support to OSSs, addressing a number of important issues: increased bit rate, joint analysis of...
Programmers hoping to exploit multi-core processors must split their applications into threads suitable for independent, concurrent execution. The lock-based concurrency of many existing languages is clumsy and error prone - a barrier to writing fast and correct concurrent code. The Actor model exudes concurrency - each entity in the model (an Actor) executes concurrently. Interaction is restricted...
