“…Although the problem is similar to classical node mobility in wireless environments, virtual machine migration can also have additional challenges not addressed in wireless networking. Live migration is an example of node mobility with no duality in wireless networking [27], [28]. Live migration requires preserving the current state of all processes in execution.…”

Abstract-We review the main challenges and survey promising techniques for network interconnection in the Internet of the future. To this end, we first discuss the shortcomings of the Internet's current model. Among them, many are consequence of unforeseen demands on the original Internet design such as: mobility, multihoming, multipath, and network scalability. These challenges have attracted significant research efforts in the latest years because of both their relevance and complexity. In this survey, for the sake of completeness, we cover several new protocols for network interconnection spanning both incremental deployments (evolutionary approach) and radical proposals to redesign the Internet from scratch (clean-slate approach). We focus on specific proposals for future internetworking such as: Loc/ID split, flat routing, network mobility, multipath and content-based routing, path programmability, and Internet scalability. Although there is no consensus on the future internetworking approach, requirements such as security, scalability, and incremental deployment are often considered.

“…The data plane performs the function of packet forwarding. All the router architectures using the combination of data and control plane proposed by Pisa et al concentrates on performance in terms of delay [54]. The VROOM [55,56] router architecture also concentrates on the performance in terms of delay using control plane virtualization.…”

Horizontal IaaS federation exploits datacenter for federation of IaaS provider by supplying virtual nodes (e.g. virtual machines, virtual switches, and virtual routers) and virtual links. Today's datacenters for cloud computing do not supply full network virtualization in terms of user-level network management and user-agreed network topology. The datacenters lack the basic security services required for the collocation of tenants' virtual networks. The network virtualization research projects from academia and industry support full network virtualization but lack the basic security services required for the collocation of tenants' virtual networks. This paper investigates the security issues in four areas namely, (a) monolithic IaaS cloud, (b) network virtualization research projects, (c) datacenter network virtualization and (d) virtual resources to incorporate full network virtualization environment in horizontal IaaS federation. Further, it presents the security related qualitative comparisons of datacenters, network virtualization research projects and virtual resources to incorporate full network virtualization in horizontal IaaS federation.

“…The frequency of execution will logically depend on the variation of the traffic matrix. Since a migration should not last less than a second [12], for 1,000 machines our implementation should work correctly. The execution time of VMP is analyzed in Section IV.…”

Abstract-Data centers rely on virtualization to provide different services over a shared infrastructure. The placement of the different services and tasks in the physical machines is crucial for the performance of the whole system. A misplaced service can overload some network links, lead to congestion, or even connection disruptions. On the other hand, virtual machine migration allows reallocating services and changing the traffic matrix, leading to more efficient use of bandwidth. In this paper, we propose a Virtual Machine Placement (VMP) algorithm to (re)allocate virtual machines in the data center servers, based on the current traffic matrix, CPU, and memory usage. Analyzing the formation of community patterns in terms of traffic using graph theory, we are able to find virtual machines that are correlated because they exchange high amount of data. Those virtual machines are aggregated and allocated to servers as close as possible to each other, reducing traffic congestion. Our simulation results show that VMP was able to improve the traffic distribution. In some specific cases we were able to reduce 80% of the core traffic, concentrating it at the edge of the network.
