The recent emergence of cloud enabled applications raises security concerns increasingly, since more and more personal and company data is outsourced. The security of single systems and services was broadly treated in the past. Cloud systems and services require a more detailed observation of their security requirements and fulfillment, since a huge amount of services and systems coexist on one virtualization layer without knowing other systems on the same layer. Only the cloud provider has a rare idea of these systems' behavior in his own cloud environment. Therefore this work proposes a network security approach which is aware of all existing systems and services hosted by at least one cloud provider. The main idea is to maintain a logically centralized database that provides latest security related information about each system or service. Using this knowledge base, our approach ponders a systems' security score, security requirements given by the systems' owners and the cloud provider, and reconfigures the network accordingly to meet the security requirements for every system. In addition, the reconfiguration process can be used to redirect traffic to additional security systems, in order to obtain more detailed information about a system and therefore increase the accuracy of the specific systems' security score.

As the number and variety of connected devices increase, most end-users find themselves unable to manage their home networks properly, not having enough time and/or knowledge to do so. In this paper, we propose a new approach to remove this burden from them, by fully virtualizing the home network and delegating its management and operations to the ISP, while keeping end-users in control. We furthermore define the architecture of our software-based Majord'Home solution. Acting as a majordomo of the home, it handles a representation of the home objects and network constraints, automates the connectivity between heterogeneous elements and thus meets the needs of end-users. We finally describe the first version of our on-going implementation as a proof of concept.

In network management applications, load balancing has typically been achieved by manually configuring the application in-situ or using configuration information generated using offline tools. As networks increase in scale and heterogeneity, management applications are being designed to take advantage of scalable computer hardware and often have multiple instances, each of which bears a portion of the management load of the network elements or functions being managed. The communication between management applications and the network elements they are managing is often stateful, posing a challenge for load balancing because connections must be managed if responsibility for managing some network elements change from one instance to another during load balancing. In this paper, we describe an algorithm that enables load balancing of telecommunication management applications for an arbitrary number of VNFs (Virtual Network Functions). The algorithm, triggered by NFV (Network Function Virtualisaton) orchestration, is horizontally scalable and there is no single point of failure once two or more management application instances are running.

Content centric networking (CCN) has attracted a great deal of attention as a network that can efficiently deliver content. In CCN, content is delivered using the content name, instead of the host IP address, from cache memory implemented at routers. The nodes sending content are not explicitly indicated, and content is delivered from routers that have copies of content on the routes where the Interest packets are transmitted. Therefore, as a result of introducing CCN in ISP networks, the pattern of traffic exchanges among ISPs will change considerably. Customer ISPs normally pay a transit fee to transit ISPs based on the traffic volume transmitted on the transit links. Therefore, the introduction of CCN by ISPs will affect the profit of ISPs. CCN is introduced and operated by ISPs based on their business judgment, so it is important to estimate how CCN affects ISP profit in order to investigate the likelihood of CCN spreading among many ISPs. In this paper, we formalize the profit of ISPs when implementing CCN, assuming a hierarchical topology of ISPs in three levels and investigate the likelihood of CCN spreading through numerical evaluation.

Network Functions Virtualization (NFV) is a new approach to design, deploy, and manage network functions. In a recent past, such functions used to be implemented at hardware. This approach, besides effective, presents many disadvantages such as increased operational costs, difficulties to scale up or down the network, and deploy new functions. The rise of virtualization technologies, on the other side, provides new ways to rethink about network functions. Instead of specialized and expensive hardware, multiple network functions can share the same commodity hardware, thus contributing to a better utilization of resources. Besides its advantages, NFV is still on its early stages of employment. Important aspects are not yet being investigated by the research community. For example, to this date, the management requirements of NFV remain unclear. Therefore, the present paper addresses this subject, it presents a realistic network function request, which is used to identify management requirements in the context of a specific NFV enabler platform called ClickOS.

Network Functions Virtualization (NFV) is an upcoming paradigm where network functionality is virtualized and split up into multiple building blocks that can be chained together to provide the required functionality. This approach increases network flexibility and scalability as these building blocks can be allocated and reallocated at runtime depending on demand. The success of this approach depends on the existence and performance of algorithms that determine where, and how these building blocks are instantiated. In this paper, we present and evaluate a formal model for resource allocation of virtualized network functions within NFV environments, a problem we refer to as Virtual Network Function Placement (VNF-P). We focus on a hybrid scenario where part of the services may be provided by dedicated physical hardware, and where part of the services are provided using virtualized service instances. We evaluate the VNF-P model using a small service provider scenario and two types of service chains, and evaluate its execution speed. We find that the algorithms finish in 16 seconds or less for a small service provider scenario, making it feasible to react quickly to changing demand.

Virtual Machine (VM) live migration is key for implementing resource management policies to optimize metrics such as server utilization, energy consumption, and quality-of-service. A fundamental challenge for VM live migration is its impact on both user and resource provider sides, including service downtime and high network utilization. Several VM live migration studies have been published in the literature. However, they mostly consider only system level metrics such as CPU, memory, and network usage to trigger VM migrations. This paper introduces ALMA, an Application-aware Live Migration Architecture that explores application level information, in addition to the traditional system level metrics, to determine the best time to perform a migration. Based on experiments with three real applications, by considering application characteristics to trigger the VM live migration, we observed a substantial reduction in data transferred over the network of up to 42% and the total live migration time decrease of up to 63%.

Multimedia conferencing applications play a critical role in business and everyday life. However, scalability and elasticity remain quite elusive, even though they are the keys to efficiency in resource usage. A cloud-based approach could solve the scalability and elasticity issues and bring other benefits such as an easy introduction of new applications. This paper proposes a cloud infrastructure that relies on fine-grained conferencing substrates. These substrates are virtualized and shared by conferencing applications. They enable scalability and elasticity.

In this paper, we propose an adaptive allocation scheme which determines the number of time slots for each user in an OFDM/TDMA system using the Effective Bandwidth theory. For that purpose, we developed an algorithm to adaptively estimate the parameters of the MWM (Multifractal Wavelet Model) traffic model that allow us to calculate the effective bandwidth for the incoming traffic flows. We evaluate the performance of the proposed adaptive allocation scheme through simulations using real traffic traces.

Software-Defined Networking (SDN) attracts attention as a technology to control and manage IP networks, which are inherently designed to be operated autonomously and decentralized, in a centralized manner. There have been proposed some SDN protocols like OpenFlow, but they have a restriction that existing legacy network devices which do not support SDN protocols are not controllable. In this paper, we allow an administrator to manage a wide-area distributed network composed of campus networks and data-center networks in which network devices do not have SDN features, in a single unitary policy, under an assumption that the backbone network supports SDN protocols like OpenFlow. We propose a network management system which generates necessary configuration based on defined network specification and sets the configuration to devices automatically and reactively, based on our Service-Defined Networking (SvDN) concept.
