“…In such a case, we expect a low number of flows would actually need to be migrated to a different InP. In such cases, related work to handle mobility in virtualized infrastructures could be applied [8], [9]. Containers We use unikernels to build lightweight proxies, relying on the enhancements to TCP implementation described in [44].…”

We explore the opportunities and design options enabled by novel SDN and NFV technologies, by re-designing a dynamic Content Delivery Network (CDN) service. Our system, named MOSTO, provides performance levels comparable to that of a regular CDN, but does not require the deployment of a large distributed infrastructure. In the process of designing the system, we identify relevant functions that could be integrated in the future Internet infrastructure. Such functions greatly simplify the design and effectiveness of services such as MOSTO. We demonstrate our system using a mixture of simulation, emulation, testbed experiments and by realizing a proof-of-concept deployment in a planet-wide commercial cloud system.Index Terms-NFV, Cloud, Edge Cloud, SDN, CDN, TCP proxy.performance of dynamic web content delivery from an origin server. The motivation for selecting a CDN as application is twofold. First, CDNs are widely deployed and play a critical role in today's Internet [37]. Second, building a CDN requires a fine engineering work to balance performance, scalability and costs. Complex algorithms for content placement and routing [32], fast software implementations [27], tuning of network protocols [3] are just few of the required building blocks, which allow us to touch a large variety of topics. Furthermore, the decision to target dynamic content delivery focuses our discussion on networking-related issues, rather than on cache dynamics as it is the case for static content delivery [49].MOSTO dynamically places virtualized proxies in the network to accelerate TCP flows. In effect, we revisit a wellknown technique for TCP acceleration [30], i.e., using a chain of TCP proxies to connect the end-points, in the light of recent advances on network function virtualization [35] and programmable network devices [12]. In particular, we provide two main contributions. First, we describe the way MOSTO addresses the following issues:• Mapping clients to ingress proxies and intercepting client network traffic; • Selecting proxies' locations and proxies chains for a given TCP flow; • Scaling proxies forwarding throughput to minimize the cost of running the system.

“…Indeed, when the relocated VM is hosted in a DC connected to a different IP network, or even within a different domain, some kind of IP mobility solution must be adopted, such as those based on the so-called identifier/locator split principle [25,26]. Another possibility is to take advantage of the highly flexible, dynamic network reconfiguration capabilities of SDN, which allows to migrate an entire virtual network from one DC to another [27], and to smartly reroute external traffic after a VM has been migrated [28].…”

The idea of pay-per-use computing incarnated by the cloud paradigm is gaining a lot of success, both for entertainment and business applications. As a consequence, the demand for computing, storage and communication resources to be deployed in data center infrastructures is increasing dramatically. This trend is fostering new forms of infrastructure sharing such as cloud federations, where the excess workload is smartly distributed across multiple data centers, following some kind of mutual agreement among the participating cloud providers. Federated clouds can obtain great advantages from virtualization technologies and, in particular, from multiple virtual machine live migration techniques, which allow to flexibly move bulk workload across heterogeneous computing environments with minimal service disruption. However, a quantitative characterization of the performance of the inter-data center network infrastructure underlying the cloud federation is essential to guarantee user's quality of service and optimize provider's resource utilization. The main contribution of this paper is the definition and application of an analytical model for dimensioning inter-data center network capacity in order to achieve some given performance levels, assuming some simple multiple virtual machine live migration strategies. An extensive set of results are provided that allow to understand the impact of the many parameters involved in the design of a cloud federation network.

“…This approach distributes network events opportunistically, based on the assumption that a large fraction of these events can be locally handled; indeed this is an expected behavior in Wide-Area Networks (WAN) where interactions within local networks do not require the knowledge from other networks to be handled. Further details on this approach can be found in [44], [45].…”

Abstract-Software-Defined Networking (SDN) has drawn increasing attention from both industry and academia, owing to its premise to simplify the management and control over large networks. While the SDN technology was initially deployed within datacenters, there are currently early deployments of SDN in Wide-Area Networks; SDN is further envisioned to be deployed in the near future within fixed and mobile networks.In this paper, we show that the envisioned deployment of SDN within operator networks opens the doors to novel network security services that the operators can efficiently offer. More specifically, we propose in this work two exemplary operator services; our first solution enables the construction of secure location proofs for registered network users. Our second solution offers users the possibility to request the setup of network paths that are tailored to their specific security constraints, e.g., that only cross domains regulated by appropriate legislations which match their security policies. We show that this can be securely and efficiently attained by leveraging basic functionality from the OpenFlow protocol. In this respect, we evaluate the feasibility of our proposals by means of implementation within a realistic testbed composed of hardware OpenFlow-enabled switches; our findings suggest that our proposals can be deployed with minimal overhead within existing SDN-enabled networks.
