“ACTIVE OVERLAY NETWORK”
Ricardo Lopes Pereira,
Departamento de Engenharia Informática –
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.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
