Aiming at satisfying in a cost-effective manner the forecast traffic growth that future mobile networks will need to support, traditional distributed Radio Access Networks (RANs) are evolving towards centralized architectures. Specifically, the Cloud-RAN (C-RAN) architecture has shown that can alleviate to some extent the ever increasing Total Cost of Ownership in mobile networks. The current trend...
The expected explosion of services offered in the cloud has revealed new paradigms in telecommunication networks and motivated research to satisfy the needs arising. Interconnection between facilities hosting computing resources or between computing resources and end-users may require service-specific Service Level Agreement (SLA) parameters. In this paper, we study the minimum connectivity requirements...
The growth of data traffic related to datacenter (DC) interconnection and the expected explosion of services requiring intensive use of telecom networks, such as video and mobile services, are contributing to the increment of the traffic that transport networks need to support. In fact, Cisco has recently forecast that in the next few years IP traffic related to video services will correspond up to...
Mobile applications and services relying on mobility prediction have recently spurred lots of interest. In this paper, we propose mobility prediction based on cellular traces as an infrastructural level service of telecom cloud. Mobility Prediction as a Service (MPaaS) embeds mobility mining and forecasting algorithms into a cloud-based user location tracking framework. By empowering MPaaS, the hosted...
Cloud computing is one of the most widely used terms in IT today. Some experts regard cloud computing as hype, but others believe that clouds will have a longer future. Although web 2.0 companies have warmly welcomed clouds, mobile operators have taken a more cautious approach to this new phenomenon. However, new opportunities are opening up to operators, and a number of steps can be followed to take...
