“…SDN provides a convenient control framework for these flexible multilayer networks [415]. Several research networks, such as ESnet, Internet2, GEANT, Science DMZ (Demilitarized Zone) have experimented with these multilayer networking concepts [420], [421]. In particular, SDN based multilayer network architectures, e.g., [354], [422], [423], are formed by conjoining the layered technology regions (i) in vertical fashion i.e., multiple technology layers internetwork within a single domain, or (ii) in horizontal layering fashion across multiple domains, i.e., technology layers internetwork across distinct domains.…”

The emerging Software Defined Networking (SDN) paradigm separates the data plane from the control plane and centralizes network control in an SDN controller. Applications interact with controllers to implement network services, such as network transport with Quality of Service (QoS). SDN facilitates the virtualization of network functions so that multiple virtual networks can operate over a given installed physical network infrastructure. Due to the specific characteristics of optical (photonic) communication components and the high optical transmission capacities, SDN based optical networking poses particular challenges, but holds also great potential. In this article, we comprehensively survey studies that examine the SDN paradigm in optical networks; in brief, we survey the area of Software Defined Optical Networks (SDONs). We mainly organize the SDON studies into studies focused on the infrastructure layer, the control layer, and the application layer. Moreover, we cover SDON studies focused on network virtualization, as well as SDON studies focused on the orchestration of multilayer and multidomain networking. Based on the survey, we identify open challenges for SDONs and outline future directions

“…Apesar da infraestrutura local ter melhorado significativamente e as redes terem atingido um desempenho de altíssima velocidade em seu ponto final, obter um ótimo desempenho entre as redes envolvidas fim a fim é ainda um desafio. É necessário pesquisar, entender e desenvolver tecnologias e ferramentas de análise de desempenho de redes com o envolvimento de diversos protocolos em várias camadas de 1 Em junho de 2014, foi inaugurada a RedeRio Metropolitana (REDECOMEP-Rio), uma parceria da RedeRio/FAPERJ com a RNP/MCTI. Esta é uma infraestrutura de fibras óticas próprias que formam uma rede de alta velocidade para as instituições de ensino, ciência, tecnologia, inovação e de governo na cidade do Rio de Janeiro.…”

Resumo: Este trabalho demonstra a utilização da ferramenta de medição e geração de tráfego de dados Transport Control Protocol (TCP) e User Datagram Protocol (UDP) conhecida como IPERF. Uma ferramenta útil para engenheiros e administradores de rede, do tipo cliente/servidor, desenvolvida com código livre e gratuita. Ela permite, como uma de suas principais vantagens, a alteração de parâmetros TCP, tal como o tamanho da janela TCP, além de exibir relatórios de banda nos modos TCP e UDP, e relatórios de jitter e perda de pacotes no modo UDP. Neste documento, são exibidos alguns casos em que a ferramenta é útil e como ela pode ser utilizada para auxiliar na análise de desempenho de redes TCP/IP.

“…The concept of moving files on L2 paths is relatively new and championed by the scientific computing community, but most papers focus on the transfer of a single large dataset consisting of multiple files to a single receiver [14], rather than on a continuous file stream to multiple receivers. Given the novelty of the problem statement, our solution to this problem is correspondingly new.…”

On Using Software Defined Networks for File-stream Distribution

In a meteorology data-distribution application, streams of files are served to hundreds of receivers every day on unicast TCP connections. Software Defined Networking (SDN) offers a more-scalable solution in which a rate-guaranteed Layer-2 (L2) multipoint virtual topology can be provisioned to have switches perform Ethernet-frame multicasting to support this application. A characterization of the file streams shows that file sizes and file inter-arrival times are both right skewed. The objective of this thesis is to design an algorithm for determining the rate of the Layer-2 multipoint virtual topology, and the size of the sending-host buffer, based on traffic characteristics of the file streams and performance requirements. Furthermore, the traffic characteristics are not exactly the same from day-to-day. An empirical method is proposed to determine the ideal rate and buffer size based on a day's traffic, which are then used along with the current rate and buffer size in an Exponential Weighted Moving Average (EWMA) scheme to determine the rate and buffer size for the next day. Our method was evaluated using metadata obtained for the top five file-streams of this meteorological data distribution, and found to be effective. This thesis also describes our experience with deploying a multi-domain SDN that supports dynamic L2 path service, and offers insights gained from this experience. OpenFlow switches with two controllers, Open Exchange Software Suite (OESS) to perform intra-domain topology discovery and path provisioning actions, and On-Demand Secure Circuits and Advance Reservation System (OSCARS) for inter-domain provisioning, were deployed in several university campuses, and regional and core research-and-education networks (RENs). Our experience demonstrated that this architecture can support global-scale multi-domain dynamic L2 path service. We identified modifications required to the protocols and controllers for improving user experience and scalability iv v of this dynamic L2 path service. We also developed a methodology for provisioning inter-domain multipoint VLANs, and demonstrated the successful use of these VLANs for a multicast application.
