Enabling Future Internet Architecture Research and Experimentation by Using Software Defined Networking

Internet core protocols were designed in the seventies and after four decades and a huge success, most of that initial design is still in place. As stated by Moores law, current digital devices offer a huge processing capacity when compared to the computational resources of the early Internet. Moreover, physical links, wired or not, offer great connectivity and high throughput capacity. New applications bring a new set of requirements that the Internet is not able to satisfy in a proper way. The Internet architecture must be reviewed and several research groups are engaged in this design. Software Defined Networking (SDN), currently materialized in OpenFlow, represents an extraordinary opportunity to rethink computer networks, enabling the design and deployment of a future Internet. This paper presents SDN based technologies available, describes some research initiatives and discusses how the research community can use them to shape future Internet architecture.

A Security Framework to Protect against Social Networks Services Threats

Despite the security policies, standards, awareness strategies and tools currently in place, employees are still involving in risky behaviors that put business at risk. The growth and proliferation of Social Networks Services (SNS), among other threats, have made possible new leakage avenues for sensitive data, and malware spread. To address these security issues, network and security managers often turn to network policy management services such as firewall, Intrusion Prevention System (IPS), antivirus, and Data Loss Prevention systems (DLP). However, without a consistent strategy the desired control may be circumvented. As its outcome, this paper addresses a security framework to protect corporate information against the threats related to SNS.

On the analysis of multicast traffic over the Entity Title Architecture

New applications bring a new set of requirements that the Internet is not able to satisfy in a proper way. Internet architecture must be reviewed and researchers from all over the world are engaged in the design of a new Internet. Software Defined Networking (SDN), which is materialized in OpenFlow, represents an extraordinary opportunity to rethink computer networks. In this paper, taking advantage of SDN and the concepts of our previous work regarding the Entity Title Model, we present a proof of concept OpenFlow based implementation of the Entity Title Architecture. It is a clean slate network architecture for future networks where multicast and mobility are seamlessly provided. By using this implementation, we describe some experiments conducted and present a comparison between a video application implemented first, using the TCP/IP stack and then using our architecture focusing on its multicast capabilities and by consequently reducing bandwidth consumption. The results presented in this paper show that this consumption near the source by using our architecture remains constant while using TCP/IP it increases monotonically.

Horizontal Address Ontology in Internet Architecture

The ontology is used in different areas of computer systems for the explicit representation of conceptualizations, but there are few studies on the application of ontology in the intermediate and lower layers of computer networks. This paper extend the studies on ontology for the network and transport layers of the TCP/IP architecture, to address the human needs that demands technological requirements for the distributed systems. These systems have to address hosts, users and applications. This work presents one proposal to the horizontal addressing in the Internet architecture to collaborate in the improvement of distributed systems.

Distributed Systems Ontology

Applications in distributed systems, have increased their complexity and demands of new requirements, since the TCP/IP design, e.g. requirements for mobility, security, QoS and throughput. The access technologies also have a history of continuous development, with the increase of its capacity and new transmission medium. This evolution in applications and new access technologies have not been followed by significant development in the main protocols of the layers 3 and 4 in the Internet architecture, as the IP, TCP and UDP. This study shows ontological deficiencies in the Internet architecture in supporting new applications requirements and proposes improvements for the next generation Internet, based on the applications needs.

Software defined eHealth networking towards a truly mobile and reliable system

The eHealth technology will change the way the health system is handled, mainly in developing countries, such as Brazil, where there is a huge shortage of healthcare professionals to assist the patients, especially for those living in rural and remote areas. The Context-Aware Mobile Approach (CAMA) seeks to improve the Brazilian primary healthcare system through context-aware eHealth facilities, such as people mobility, expecting to change the way that healthcare services are applied, managed, and maintained to achieve efficiency and safety for both patients and hospital staffs. Since this type of technology will handle vital parameters of people, it is mandatory that the involved network infrastructure can provide dependability and reliability so it can fulfill their role properly. This paper presents a network infrastructure based on the Software Defined Networking (SDN) paradigm to enable quality-oriented mobility control capabilities in the CAMA approach, to deploy mobility prediction, Point of Attachment (PoA) decision and handover setup meeting both application quality requirements and current wireless quality conditions, then improving the dependability and reliability of the eHealth biofeedback systems.

Horizontal Addressing by Title in a Next Generation Internet

In this work in progress, a new proposal is introduced for Internet horizontal addressing through the unification of application, host, and user addresses in entity title. With this unification it is possible the host addressing in Internet without IP use, as well as the routing of applications without the use of TCP, UDP, or SCTP ports. For so, it is proposed to create one Domain Title Service in Internet architecture to enable the addresses unification and that the network structure can receive information about the entities’ needs, and then meet them.

Entity title architecture extensions towards advanced quality-oriented mobility control capabilities

The emergence of new technologies, in addition with the popularization of mobile devices and wireless communication systems, demands a variety of requirements that current Internet is not able to comply adequately. In this scenario, the innovative information-centric Entity Title Architecture (ETArch), a Future Internet (FI) clean slate approach, was design to efficiently cope with the increasing demand of beyond-IP networking services. Nevertheless, despite all ETArch capabilities, it was not projected with reliable networking functions, which limits its operability in mobile multimedia networking, and will seriously restrict its scope in Future Internet scenarios. Therefore, our work extends ETArch mobility control with advanced quality-oriented mobility functions, to deploy mobility prediction, Point of Attachment (PoA) decision and handover setup meeting both session quality requirements of active session flows and current wireless quality conditions of neighbouring PoA candidates. The effectiveness of the proposed additions were confirmed through a preliminary evaluation carried out by MATLAB, in which we have considered distinct applications scenario, and showed that they were able to outperform the most relevant alternative solutions in terms of performance and quality of service.

FINLAN Packet Delivery Proposal in a Next Generation Internet

There are several studies on the TCP/IP architecture evolution since the 80s, however, due to the great installed and used base there are difficulties in implementing improvements in large scale. In the last years, the number of researches that discuss the next generation Internet has grown, and this paper is a study collaboration in this area. This paper proposes the adding of a mechanism to guarantee the packet delivery in FINLAN, which is a protocol that enables the communication in networks with connectivity in layer 2 without the use of IP, TCP, and UDP protocols.

Title model ontology for future internet networks

The currently Internet foundation is characterized on the interconnection of end-hosts exchanging information through its network interfaces usually identified by IP addresses. Notwithstanding its benefits, the TCP/IP architecture had not a bold evolution in contrast with the augmenting and real trends in networks, becoming service-aware. An Internet of active social, mobile and voracious content producers and consumers. Considering the limitations of the current Internet architecture, the envisaged scenarios and work efforts for Future Internet, this paper presents a contribution for the interaction between entities through the formalization of the Entity Title Model.
