Workshop on Clouds and Applications

In conjuction with SBRC 2019


The WCGA series of workshops purpose is to act as a forum for technical presentations of relevant ongoing research activities in the areas of infrastructure and virtualized infrastructure, services and applications in different areas, bringing together researchers and professionals actively acting in this areas. The workshop also tries to establish multi-institutional collaborative networks and technical and scientific competence groups, as well as to strengthen ongoing activities. The workshop has been evolving to theme of Clouds since 2010, always approaching large scale computational environments. In 2019, WCGA will reach its 17th edition, get consolidated as one of the main workshops in the area of computer networks and distributed systems. Best paper of the workshop should be invited to a journal special issue.

Distributed Cloud: A Modern Paradigm Towards 5G Networks

Moacyr Martucci Junior (USP)

Abstract: The move from 4G to 5G (Fifth Generation of Mobile Networks) promises a very significant jump in terms of network performance, with the support of millimeter waves, small cells, massive Multiple-Input and Multiple-Output, distributed cloud computing etc. being deployed to lower latency and increased throughput. The combination of these technologies is expected to deliver a 10X decrease in latency – as low as 1 ms – and a 10X increase in speed – higher than 1 Gbps. Network slicing, a key aspect of 5G networks, will be important for the edge. Internet Service Providers (ISPs) can implement slicing without 5G, but it will likely become much more prevalent with 5G and its emerging specifications that mandate the partitioning of the data, control and management planes to separate environments that can be created. Thus, serving individual customers or deliver specific services, giving ISPs the opportunity to more easily support multi-tenancy, individual customers and use cases in order to meet each slice´s unique Service-Level Agreements. The advent of 5G is helping to drive demand for distributed edge architectures because of the technology advancements that it promises. The Internet Protocol (IP) network will need to support data, control, and management plane separation across a multi-site network fabric as a result. All these changes are leading to new requirements for the IP network and network fabric. For the IP network, this means that traffic will need to be processed at the edge in thousands of mini -and micro- data centers, some of which may be located in the Radio Access Network. The IP network, ideally leveraging the flexibility and cost-effectiveness of white boxes, will need to support a network fabric that can make this large number of sites appear, logically, as a more manageable set of network fabrics. The white boxes will need to offer some sort of SDN (Software-Defined Networking) control and ideally some sort of network fabric that will make a large number of sites appear, logically, as a set of fewer network fabrics. Using Application Programming Interfaces, these fabrics will need fabric-wide programmability, helping ISPs improve their operational efficiency at scale. SDN brings easier network automation and service orchestration to improve operational efficiency. 5G Network slicing will drive the need for the IP network to support data, control, and management plane separation across a multi-site network fabric, which should have a central view of network state, but with that knowledge and intelligence distributed across the whole fabric and then throughout the distributed cloud.

Bio: Full professor at the Department of Engineering and Digital Systems of Escola Politécnica of Universidade de São Paulo and the Coordinator of the Institute for Studies Brazil Europe, a Research Support Nucleus under the Research Pro-rectory of the USP. Martucci is also the Brazilian National Contact Point in Program Horizon 2020 and the NCP in the program ideas to ERC (European Research Council) to European Commission and participates in the Brazil-EU group within the Action "5G and the Future of Mobile telecommunications in Brazil and Europe" at the Ministry of Communications and Ministry of Planning in Dialogue Sector BR-EU. His main interest areas are Information Systems, Open Systems, Computer Networks and Automation, 5G and Future Internet and Internet of Things with applications in smart cities.
