“…• assist in the discovery of architectural elements, and • to validate outcomes. There are six different use scenarios [116], which are divided into two major clusters: network resources used to transfer data and the entire infrastructure is used to provide networkbased services (including computing and storage resources). The clusters are respectively titled data domain and infrastructure domain.…”

The global growth of the Internet continues with an increase in accessibility, connected users and new applications in emerging fields like egames, augmented and virtual reality. Technologies that improve reliability whilst reducing cost and latency are being developed. However, before the Internet can sustain the growth in utilisation and new applications there are challenges to overcome. One of the key challenges remaining is to develop new mechanisms for intra and inter-domain federation that facilitate fast, reliable, and secure sharing of reachability and routing information. Software Defined Networking (SDN) is being introduced to address control and management challenges at domain boundaries. This paper reviews the current state of domain federation and discusses the potential approaches that utilise SDN for a nextgeneration solution.

“…The following technologies used to maintain these configurations: a) ODL Inter SDN controller communication (ODL SDNi): Different ODL controllers can use this feature to instantly communicate to each other and pass any changes in the topology to each other, such as VMs relocation [13] [17]. Two ODLs are configured on LivCloud and Amazon instance to deploy SDNi between both sites.…”

Abstract-Cloud providers offer their IaaS services based on virtualization to enable multi-tenant and isolated environments for cloud users. Currently, each provider has its own proprietary virtual machine (VM) manager, called the hypervisor. This has resulted in tight coupling of VMs to their underlying hardware hindering live migration of VMs to different providers. A number of user-centric approaches have been proposed from both academia and industry to solve this issue. However, these approaches suffer limitations in terms of performance (migration downtime), flexibility (decoupling VMs from underlying hardware) and security (secure live migration). This paper proposes LivCloud to overcome such limitations. An open-source cloud orchestrator, a developed transport protocol, overlay network and secured migration channel are crucial parts of LivCloud to achieve effective live cloud migration. Moreover, an initial evaluation of LAN live migration in nested virtualization environment and between different hypervisors has been considered to show the migration impact on network throughput, network latency and CPU utilization. The evaluation has demonstrated the need for optimization within the LAN environment.
