We present an architecture for cloud networking, the provision of virtual infrastructure in a multi-administrative domain scenario, where data centre and network operators interact through defined interfaces to provide seamless virtual infrastructure. To support this scenario we introduce the flash network slice, dynamic elastic network connections that(More)
One of the main challenges in agriculture is to sustainably meet the demand for food while preserving natural resources for future productions. Information Technology can assist producers to make better decisions by providing them with data and tools that enhance decision-making process, consequently allowing better management of the natural resources.(More)
Infrastructure as a Service (IaaS) provides the capability to deploy infrastructure on demand, but today there are gaps in the IaaS model for network connectivity, especially when user and/or application require guaranteed connectivity between the deployed infrastructures. This problem is aggravated when virtual infrastructures are geographically(More)
Network virtualization is seen as the fundamental underlying technology for enabling future Internet services. Mapping virtual networks onto a substrate network is a well-known NP-hard problem. Therefore, some authors propose heuristic based strategies by allocating virtual networks in two uncoordinated steps: mapping virtual nodes and virtual links(More)
A "network embedded cloud", also known as a "carrier cloud", is a distributed cloud architecture where the computing resources are embedded in, and distributed across the carrier's network. This idea is based on a transformation of carrier-grade networks toward a platform for cloud services and the emergence of cloud computing in a telecommunication(More)
This paper presents the problems for dynamically deploying applications in a multi-tenant federated environment where end-to-end isolation, on-demand scalability and Quality of Service are critical factors. In addition, we propose an “framework” that tackles these issues through the collaboration between data centres and network operators.(More)
This paper presents the distributed processing feature for Trade Wind, a cloud deployment and management solution. The main objective of this research is to evaluate performance and feasibility of this feature for big data applications. A prototype has been created and tested in the calculation of monthly average temperature and humidity based on data from(More)
Resource management in distributed environments, such as Cloud virtualized networks, is one of the main concerns of infrastructure providers. Despite many advantages of centralized solutions (such as the facility of implementation and management), their unique point of failure and the lack of scalability make us consider the use of distributed and autonomic(More)
