“ACTIVE OVERLAY NETWORK”

Abstract:
The size of the Internet and the applications used on it, much of which were unforeseen when the IP protocol was designed, have exposed limitation on the TCP/IP stack.
The networking community has been able to respond with new protocols and modifications to the existing ones, yet few have been deployed in the global Internet.
The nature of the Internet, a combination of networks under distinct administrative control, makes global coordinated efforts for protocol upgrade very difficult or impossible.
Some protocols require new software to be installed on all the end-nodes while others require it be installed on all the routers.
The realisation that protocol upgrades are not more than software installations has prompted the Programmable Networks research area, which proposes that routers be dynamically and continually upgraded by running user supplied code.
Its most extreme approaches defend the use of code carrying packets, processed at each router, instead of today’s data carrying packets.
While programmable networks strive to provide a future proof evolution path, they will need to be integrated into the current Internet infrastructure in order to be successful.
This progressive integration may be accomplished using an overlay network.
The overlay may be managed using an Peer-to-Peer algorithm which will be network topology aware by integrating with inter-domain and intra-domain routing algorithms.
This work consists in the definition of a global scale active networking framework, named Overlay Active Network (OAN), which will provide APIs for passive traffic integration with active applications.
QoS, accounting and security support is included, reflecting the needs of the different stack-holders.
Several innovative network services are defined, allowing their implementation, in the form of active applications, to be used to test the proposed framework.

Upcoming Events
Research data repositories and tools for human genomics data sharing

Inform the human research community of the status and availability of BioData.pt Local EGA and discuss its need and usability challenges.
The European Genome-phenome Archive (EGA) is a repository for all sequence and genotype experiment types, including case-control, population, and family studies. The EGA will serve as a permanent archive that will archive several levels of data, including the raw data (which could, for example, be re-analysed in the future by other algorithms) as well as the genotype calls provided by the submitters.
Responding to national regulations over human data sharing and other constraints, BioData.pt deploys and operates a Local EGA instance and tools that allow data discovery of genomic and phenoclinic data, following the GA4GH standard and international best practices.
This workshop aims at informing the human research community of the status and availability of BioData.pt Local EGA and discuss from several perspectives its need and usability challenges.
Further details and registration are available here.

The 13th Lisbon Machine Learning School | LxMLS 2023

The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)

The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
