“…As proposed in [113], the ALTO server can be implemented as an SDN application on top of an SDN controller where the ALTO client resides. In such a scenario, the ALTO protocol which is in charge of communicating both entities will behave as an A-CPI as proposed by the ONF's SDN architecture.…”

“…Faigl et al [179] present an ALTO-SDN architecture where the ALTO client is implemented as an SDN application and assumes the selection of the preferred endpoint. In theory, this decision-making should be implemented at the ALTO server, but they have decided to follow this approach because it is better to implement communication intensive applications as modules in the SDN controller.…”

“…Regarding the optimality, the reviewed literature shows that ALTO can be used to maximise network utilisation and to improve other TE-related parameters in a wide range of scenarios, including DC networks [173], WAN [175] or mobile networks [179]. However, the coarse granularity of the technology, limited to IPv4 or IPv6 addresses and prefixes, impacts directly on the multi-path computation capabilities and the re-optimisation [112].…”

Since the appearance of OpenFlow back in 2008, Software-Defined Networking (SDN) has gained momentum. Although there are some discrepancies between the standards developing organisations working with SDN about what SDN is and how it is defined, they all outline Traffic Engineering (TE) as a key application. One of the most common objectives of TE is the congestion minimisation, where techniques such as traffic splitting among multiple paths or advanced reservation systems are used. In such a scenario, this manuscript surveys the role of a comprehensive list of SDN protocols in TE solutions, in order to assess how these protocols can benefit TE. The SDN protocols have been categorised using the SDN architecture proposed by the Open Networking Foundation (ONF), which differentiates among Data-Controller Plane Interfaces, Application-Controller Plane Interfaces and Management Interfaces, in order to state how the interface type in which they operate influences TE. In addition, the impact of the SDN protocols on TE has been evaluated by comparing them with the Path Computation Element (PCE)based architecture. The PCE-based architecture has been selected to measure the impact of SDN on TE because it is the most novel TE architecture until the date, and because it already defines a set of metrics to measure the performance of TE solutions. We conclude that using the three types of interfaces simultaneously will result in more powerful and enhanced TE solutions, since they benefit TE in complementary ways.

“…Although it was originally intended for P2P networks, this protocol can be applied to any kind of network. The ALTO protocol uses two main information elements, called network map and cost map [22]. The network map contains the description of groups of hosts without including information about the connection between those groups.…”

Service placement for latency reduction in the internet of things

New services and applications become part of our daily activities as we evolve into new solutions supported by cutting-edge paradigms, like the Internet of Things and Smart Cities. In order to properly achieve the benefits theoretically provided by these models, new kinds of services must be designed. These new services have special requirements, as well as the users that access to them. One of these requirements is low latency levels, since a delayed reply could render to chaos for applications such as eHealth and public safety. The communication infrastructure must cope with these challenges by offering innovative solutions. One of these solutions is a smart service placement system that facilitates the location of services in the proper position according to specific needs. On this paper, a service placement architecture for the Internet of Things is proposed, with especial emphasis in its main module, the Service Orchestrator, for which implementation details are provided, including a model for the service placement task. Furthermore, technologies to implement the modules from the architecture are suggested. This proposal, as well as its validation, is framed within the scope of the SusCity project.

Network architectures nowadays are not able to address the requirements of future Internet, as they are not sufficient, ossified, and are power hungry on the TCP/IP paradigm. Therefore, to promote the realizable progression toward the new paradigms and modern protocols, modern routers are required to become programmable for the flexible control and dynamic management of both power states and traffic flows. In this scenario, Software Defined Networking (SDN) is considered as an exemplary approach for providing the support of dynamic traffic flows of each node on a network. Besides the benefits that SDN brought to the networking area, there are still crucial challenges such as to design an effective, lightweight API, rich algorithms, and traffic forwarding rules for SDN layers along with the adoption of an energy efficient infrastructure that could have the least effect on the environment. The aim of this research is to drive the attention toward environment friendly adoption and implementation of SDN that could deal with the growing number of users and network equipment. For this purpose, in this research, a comprehensive review on SDN while mapping the characteristics of green computing with SDN is provided. In addition to that, the research stressed on the benefits of Green SDN through a proposed G-SDN framework. Some well-defined case studies are presented to highlight the need of greening an SDN infrastructure. Finally, various research directions are presented to the wide adoption of SDN technology for academia and industry alike. KEYWORDS green computing, green SDN, SDN, software defined networks 1 INTRODUCTION Software Defined Networking (SDN) offers a high level of flexibility, controllability, and programmability in networks with the power of centralized control. The centralized controller at SDN faces a significant performance drawback when dealing with huge network flows. 1 On the other hand, features provided by SDN allows an ease in deploying the strategies that are designed to overcome the existing problems of power and energy-waste. 2 Green computing refers to the reduction of hazard and toxic materials, improved efficiency of energy including recycling of factory wastage, 3 and it has become an integral part to enhance the reliability of each emerging computing domains. Even the cloud and green computing are applicable side by side to make greener internet and enhance services. The former techniques allow the services with ease when required at a cost of complex infrastructure. However, the later approach has edge in providing all of these services with efficient energy usage, recyclability, low environmental impact, reduced carbon emission, and much more facilities. 4 In addition, to provide the promising services to the intended users, wired and wireless networks 5,6 have been followed by many directions in prior studies 5-7 such as the closing of forward and feedback loops. 8 In this way, there exists a variety of designs such as low-power solutions with slow and fast dynamics. Solutions with sl...
