Title: Reviewing Brazilian International Collaboration Programs on IT: Challenges and Lessons Learned
Abstract: In the last years, the Brazilian government has been financially supporting a number of research projects selected from joint international open calls, especially with Europe. Important areas have been covered in such projects, such as Cloud Computing, HPC, and Future Internet. Joint projects with international partners lead to unique opportunities to Brazilian researchers, although they also pose challenges that are not often found in traditional, national projects. Opportunities and challenges are also faced by funding agencies, that need to assist researchers to achieve the full potential of international collaborations. In this talk, we will review the last international joint calls with Brazil, discussing their benefits, experiences, and lessons learned. We will also observe the faced difficulties and how such difficulties have been addressed, and finally we will provide considerations about future opportunities of international collaborations.

Abstract: Future Internet and distributed cloud (FIDC) testbed researchers in Brazil and the US are among the first participants in a developing worldwide trend toward greater federation of research cyberinfrastructure. Federation of FIDC testbeds offers a promising value proposition for both operators and end users, offering scale, geographic diversity, and resource heterogeneity, while maintaining local control over resources, policies, and cost.
Federation of FIDC testbeds occurs at several levels, but the first (and often most challenging) step is the human-to-human and organization-to-organization process of establishing trust and resource sharing agreements and the associated implementation policies. Once this step is addressed, the technical implementation may include some or all of AAA (authentication, authorization, and accounting) federation, control plane federation, and data plane federation. Established or emerging standards exist for each of these aspects of technical federation, at various levels of maturity.
Thanks to strong researcher-to-researcher relationships, there are a number of very compelling examples of federation between Brazilian and US testbeds, supporting a variety of research collaborations. There is great potential in pursuing two promising paths for expanding the power of these federations. One path is to agree upon and implement policies that simplify human-level processes, moving toward routine, automated instantiation of federated infrastructure configurations. A second path is to continue to expand research and infrastructure collaborations to a broader set of participating countries and regions.

Abstract: While cloud services have become ubiquitous to all major 21st century economic many open questions remain on how to best assimilate and leverage this new technology. In particular, many open research questions concern the relationship between cloud computing and high performance computing, the suitability of cloud computing for data-intensive applications, and its position with respect to emergent trends such as Software Defined Networking. A persistent barrier to further understanding of those issues has been the lack of a large-scale testbed where they can be explored. This is partly because a suitable experimental platform would require large investment in hardware and support for deep reconfigurability to provide the required support for reliable and reproducible research.
With funding from the National Science Foundation (NSF), the Chameleon project provides such platform to the open research community allowing them to explore transformative concepts in deeply programmable cloud services, design, and core technologies. The testbed, deployed at the University of Chicago and the Texas Advanced Computing Center, will ultimately consist of almost 15,000 cores, 5PB of total disk space, and leverage 100 Gbps connection between the sites. While the primary investment in hardware deployed so far consists of primarily of homogenous hardware to support large-scale experiments, future capabilities will support heterogeneous units allowing experimentation with high-memory, large-disk, low-power, GPU, and co-processor units. To support a broad range of experiments, the project provides a configuration system allowing full control of the software stack, from provisioning of bare metal and network interconnects to delivery of fully functioning cloud environments. This talk will describe the goals, the building, and the capabilities of the testbed.

Abstract:Nowadays the cloud computing technology allows us to integrate local resources (networks, grids and private clouds) to intensive computing centers (data centers), forming a hybrid and heterogeneous environment accessible through the Internet. However, new emerging technologies, notably Internet of Things (IoT), bring with them new requirements to support mobility, geographical distribution, location awareness and low latency, requiring a new platform. To address these new challenges the cloud is migrating to the network edge. This evolution of the cloud demands a new paradigm that extends the cloud computing services to the edge of the network, to meet a new generation of services and applications. In this talk, I will present Chameleon, the LRC (Computer Network Laboratory)/UNICAMP multicloud testbed, designed to meet the IoT requirements. Chamaleon consists of a hardware infrastructure with the capacity to hostmultiple cloud technologies and a software infrastructure to orchestrate the execution of distributed applications, integrate technologies and facilitate cooperation between the various levels of multicloud environments. Several applications that use Chamaleon will be commented, such as image processing applications, scientific workflows, sensor network applications, vehicular applications and Hadoop applications.

Abstract: Since 2009, Clemson University embarked on a series of NSF projects that led its researchers and IT engineers through an exciting learning curve for software defined networking (SDN) and cloud computing technologies. From academic explorations of NSF GENI, CC-NIE, FutureCloud to production adoption of SDN-based data center fabric, we have worked on SDN and cloud programming and integration at data center, campus, regional, national, and international scope. It is our belief that software defined infrastructures (SDIs) around the world will be increasingly federated and interoperable, allowing applications to be launched from anywhere, with highly customizable communication with other services near and far. As a result, their logical requirements, both locally and globally, will be driving the federated SDI architecture, which will shape the future Internet.

Abstract: Smart cities require a variety of new services to be available to citizens of large urban spaces, based on data coming from different sources. This will pose high demands for dynamic allocation of existing computing and communication infrastructure that currently are based on datacenters. We advocate that the management of dynamic configuration mechanisms for cloud elasticity, SDN and NFV is a key feature for enabling such new scenarios. Encouraging results with dynamic datacenter reconfiguration will be used for providing services for smart cities, such as dealing with high and varying density of people in particular locations.

Abstract: Computer systems are everywhere. Society is dependent on networked computer systems and software for everything from running the smart grid that powers your house to social networking with your family and friends. The societal dependency has raised new responsibilities for scientists to develop sound methods and practices to protect computer systems from attack, as well as protect the user against privacy threats created by ubiquitous computer systems. The methods and practices must consider both threats from attackers looking to compromise systems, as well as the privacy and human factors considerations new systems bring to users. Cyber security scientists and engineers are also faced with the daunting task of not just securing systems against lone individuals, but also nation states using computer systems to carry out their political and military agendas. In this talk, I will discuss these challenges from the viewpoint of implementing security across layers of abstraction, and designing systems that protect user privacy and that take into account the social, behavioral and economic implications of security.

Abstract: The current Internet names the hosts, leaving it to the application to locate the host with the desired data. However, with the emergence of technologies such as CDNs and the cloud, and trends such as mobility and IoT, the need to associate data with an IP address has become a hindrance. This misalignment requires enormous corrective effort at the expense of application complexity and robust security.
Named Data Networking (NDN) transforms the current network of hosts into a network of data objects. In the process, application complexity is substantially reduced and data is easily secured. A named data network is an efficient content distributor that can natively support communication models such as multicast and anycast, routing models such as multipath and data operations such as publishing, discovery and caching. In general, NDN offers a network service model that aligns better with user needs, building a stronger foundation for current and future applications.

Abstract: BGP software and policy configuration are widely acknowledged to be highly complex. A research question of interest in whether simplifications are possible to inter-domain routing protocols for best-effort IP service in the new SDN paradigm.
There is an effort called Application Layer Traffic Optimization (ALTO) underway in the IETF to define a protocol that enables applications to request and receive information such as network topology, path costs, link availability, routing policies, and end-host properties. Providers can offer network information in abstracted form since the ALTO protocol offers topology hiding. The ALTO protocol was proposed for IP-routed best-effort services. We propose to explore whether the ALTO protocol can be extended to support advance-reservation dynamic L2-path and L1-circuit services.

Abstract: In this talk, I’ll touch briefly on a number of issues. Here, I highlight two: Federated networking in the future presents a number of challenges. In a new collaborative project between Brazil, US, and Belgium, we are investigating a wide-area federated network environment where applications require deterministic network services (such as high quality video conferencing services). We are exploring research as well as technical challenges in establishing federation and coordination between three different sites located in three different continents. In particular, we are exploring how software-defined networking can be used in this federated environment to give service guarantees.
Virtual machine migration is an important requirement in a data center networking to allow resource flexibility. We want to understand how migration works with the increase the speed of underlying networks in a data center. Our initiation assessment is that scheduling algorithms needs to be network-speed aware since the network speed reduces the time taken to migration VMs. In this collaborative work, we are considering new scheduling algorithms that are network- aware to show how performance can be improved. We are further continuing this work to consider the topological structure of the data center networks in addition to network speed.

Abstract: Mininet is a popular container-based emulation environment built on Linux for testing OpenFlow applications. Using Mininet, one can compose an experimental network using a set of virtual hosts and virtual switches with flexibility. However, it is well understood that Mininet can only provide a limited capacity, both for CPU and network I/O, due to its underlying physical constraints. We propose a method for combining simulation and emulation to improve the scalability of network experiments. This is achieved first by applying the symbiotic approach to effectively integrate emulation and simulation for hybrid experimentation. For example, one can use Mininet to directly run OpenFlow applications on the virtual machines and software switches, with network connectivity represented by detailed simulation at scale. We also propose a method for using the symbiotic approach to coordinate separate Mininet instances, each representing a different set of the overlapping network flows. By effectively distributing network emulation among separate machines, one can significantly improve the scalability of the network experiments.
Abstract: Our research addresses the need to provide more capacity to accommodate the ever increasing demand for bandwidth generated by Internet traffic. At the current stage, we investigate the ability of elastic networking to provide a response to this need. The next stage will be the deployment of a new infrastructure based on a new generation of optical fibers that support space division multiplexing (SDM). Networking solutions for SDM are under investigation, as well as business and regulatory issues related with such emerging infrastructures.

Abstract: The network of a campus or a research enterprise supports multiple business operations: Network traffic associated with administration, The network must be operated with security that protects the financial and personnel data of the organization. At the same time, these networks also support scientific research processes. Researchers depend on the network infrastructure to share, store, and analyze research data from many different external sources.
Campus networks are normally not engineered to support the data movement requirements of data intensive science. Data intensive science applications experience poor performance on general purpose networks. Campuses serve multiple communities of interest. As a result, they are faced with the following challenge: How can campus networks be adapted to optimize flows from science applications without impacting the operation of their production networks?
This talk explores the concept of the Science DMZ as a methodology to reengineer the campus network to support the needs of multiple communities of interest, in particular, the science research community conducting data intensive science, alongside production operation. The implementation of a Science DMZ at FIU’s campus is described. It is a component of a project called FlowSurge: a coordinated and coherent approach to bridging among different cyberinfrastructures by building a Science DMZ at FIU that can be tailored to support the needs of high-performance science applications and data-intensive flows.
Researchers, from their laboratory, will be able to (1) generate science flows to shared CI or CI- connected resources on the campus; at other campuses; or at regional, national or international sites. (2) Orchestrate and participate in “at-scale” experiments by using FlowSurge to tailor the end-to-end path for optimized high-performance science applications and data-intensive flows. FlowSurge will enable IT and network staff at FIU to partition the campus network infrastructure to support Science flows without causing impact to general-purpose production flows on the campus.
Abstract: This year marks important developments in International Research and Education Network Infrastructure for Future Internet and High-Performance Data-Driven Science on the United States West Coast. Pacific Wave (which operates the West Coast International R&E Exchange points) has recently been awarded funding from the US National Science Foundation to upgrade its capabilities and deploy SDX functionality across its facilities in Seattle, Los Angeles, and Sunnyvale (San Francisco Bay Area) and to add access points in several other locations. This is an integral component of the international effort to interconnect research and education networks using Software Defined Networking (SDN). In addition, NSF has funded a $5 million, five-year award to UC San Diego and UC Berkeley and their collaborators to establish a Pacific Research Platform (PRP), a science-driven high-capacity data-centric “freeway system” extending the notion of a DMZ to a large regional scale. This project plans to utilize the Pacific Wave infrastructure to expand the boundaries of campus DMZ’s across a wide geographic area and eventually to international partners. The PRP will give participating universities and other research institutions the ability to move data 1,000 times faster compared to speeds on today’s inter-campus shared Internet and to establish (software defined and managed) virtual networks to support multiple science domains communities across the network. In this talk, we will discuss these developments and the associated measurement infrastructure that is being deployed to monitor network performance and troubleshoot bottlenecks. We will also describe some of the international projects that utilize the infrastructure.

He was Director of the Computer Engineering Division from 1984-1990, Vice-Provost of Academic Computing from 1994-1997, and Vice-Provost of Scholarly Technology from 1997-2006. He received an MA in Mathematics and Operations Research from Cambridge University, MS in Statistics and Computer Science from West Virginia University and Ph.D. in Computer Science from UCLA. His academic interests are in high speed, optical, and wireless networking. He has supervised more than 25 Ph.D. students and published over 150 technical papers. For the last 10 years, he has been actively involved in planning, management and implementation of advanced networking for the research and education community at the State, National, and International level. He was a member of the Board of Directors of CENIC (Consortium for Educational Networks in California), was Vice-Chair from its founding in 1997 to 1999 and Chair from 1999 to 2006. From 2005-2010 he was Principal Investigator of the TransLight/PacificWave project (part of the International Research Networks Connections Program of the US National Science Foundation), that operates the research and education exchange points on the US West Coast and, in partnership with the Australian Academic and Research Network, supports advanced connectivity through Hawaii to Australia. He continues as a consultant for CENIC on international projects with a particular focus on the Pacific Rim and Latin American partners that utilize Pacific Wave (the main academic exchange on the US West Coast), which recently received funding from the NSF to upgrade its facilities to 100G and to deploy a parallel SDX capability. He is co-PI on the NSF Network Infrastructure project TEN-II (Trojan Network II) which is experimenting with SDN capabilities and implementing a “DMZ” to support high performance networking at USC. Participants in TEN-II are part of the Pacific Research Platform based at UCSD (recently funded by the NSF to expand DMZ functionality across multiple campuses to support multiple disciplinary science domains).
Abstract: An Exchange Point is a common place where different organizations collaborate and share computing, storage and networking resources. Recently, Software Defined Networking technologies are being included into Exchange Points to optimize resource sharing and allocation. In this talk, we explore the policy space for a Software Defined eXchange, focusing on the applications that these policies support and the options that we have to express them.
