This article presents an operator's view of the evolution towards a transport network ready to support cloud services, which are hosted in data centers and reachable through the network. This work shows the reasons why current transport networks are not efficiently designed for a cloud environment, and it describes the architecture for a cloud-ready(More)
Many telecom operators are deploying their own cloud infrastructure with the two-fold objective of providing cloud services to their customers and enabling network function virtualization. In this article we present an architecture we call SHINE, which focuses on orchestrating cloud with heterogeneous access and core networks. In this architecture intra and(More)
This document proposes some experimental enhancements to the base solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6) domain. These enhancements include the use of a multicast tree mobility anchor as the topological anchor point for multicast traffic, as well as a direct routing option where the Mobile Access Gateway can provide access to(More)
The objectives of Cross Stratum Optimization (CSO) and SLA Management in multi-domain infrastructure services lead to challenges for maintaining autonomy of resource control and coordination of the SLA lifecycle. The GEYSERS project includes an approach and architecture for SLA Management to address these two problems. The conceptual foundations and(More)
This paper presents on-going research to develop the Intercloud Architecture Framework (ICAF) that addresses problems in multi-provider multi-domain heterogeneous cloud based infrastructure services and applications integration and interoperability, to allow their on-demand provisioning. The paper refers to existing standards and ongoing standardisation(More)
This paper describes a demonstration of SDN-based optical transport network virtualization and orchestration. Two scenarios are demonstrated: a dynamic setup of optical connectivity services inside a single domain as well as a multidomain service orchestration over a shared optical infrastructure using the architecture defined in the STRAUSS project.
Cloud-based infrastructures are becoming the de facto standard for service hosting through the innovation of traditional Data Centres (DCs). The availability of advanced multi-site service provisioning solutions (e.g., availability zones in Amazon EC2), is enabling the creation of advanced high-availability architectures for services and applications. These(More)
Emerging cloud applications such as real-time data backup, remote desktop, server clustering, etc. require not only more traffic being delivered between datacenters, but also dedicated and application-specific virtual optical network (VON) services to support each application's QoS and SLA level. On the other hand, another requirement is to support(More)
The recent evolution of cloud services is leading to a new service transformation paradigm to accommodate network infrastructures in a cost-scalable way. In this transformation, the network constitutes the key to efficiently connect users to services and applications. In this paper we describe the deployment, validation and demonstration of the optical(More)
The goal of the 5G Exchange project is to enable cross-domain orchestration of services over multiple administrations. The system we build allows the end-to-end integration of heterogeneous resource and service elements of a multi-vendor technology environment from multiple operators by sharing their network and compute infrastructures via NFV(More)
