Eduardo Sousa, a researcher from IT in Aveiro (coordinated by Diogo Gomes and Rui Aguiar) was at the the 3rd NFV Plugtests event to present the Network Services (NS) Heimdall Web and Heimdall Hybrid.
These NS allow to accelerate the processing of encrypted traffic (SSL / TLS) that circulates through the network, allowing to perform functions such as caching, anti-virus, compression, among others. Most important, it allows to add / remove new functions without requiring many changes. “The Heimdall Web allows all the traffic to flow into the cloud for processing. The Heimdall Hybrid Web allows part of the functions to be performed on the Edge, since there is traffic that may not even need to be processed in the cloud, with benefits in terms of response time and speed of navigation”, explains Diogo Gomes. Both Heimdall Web and Heimdall Hybrid Web can represent use cases for 5G networks, with large enterprises and telecom operators as potential costumers. Developed by the Telecommunications and Network Group of IT in Aveiro, these NS were developed in an inter-project collaboration (5GinFIRE, Smart Entercom and DEVNF).
The NFV PLUGTESTS are promoted by ETSI with the aim of accelerating the development of the standards that will support 5th generation mobile networks. The 3rd NFV Plugtests event was held in ETSI´s headquarters in Sophia Antipolis, France, from May 29 - June 8.

In project INNOVATE, a group of researcher from IT is developing bioelectronic devices to communicate with living cells and tissues. The goal is to use electronic devices to instruct cells to repair nerves and restore faulty communication paths. For instance, devices can be used to repair spinal cord injuries or to establish a bi-directional electrical communication with cancer cells. Devices can specify patterns of electrical signals to instruct the cancer cells to switch their aggressive behavior, namely their capacity to migrate and survive.
The new therapies based on bioelectronic transducers have been possible because the research team has developed ultrasensitive devices that can record the electrical activity of non-excitable cells. Unlike neurons, other types of cells, such as cancer cells, generate very week electrical signals. In order to record these faint signals the research team developed a device with surfaces coated with a forest of structures similar to micro-mushrooms that can detect very low signals. The ultra-low noise allows demonstrating that brain tumor cancer cells can engage into cooperative activity and generate complex signals patterns alike the ones used in Telecommunications. Researchers speculate this signal mechanism may interfere with brain activity and trigger epileptic seizures in patients with brain tumors.
INNOVATE is a project coordinated by Henrique Gomes from the Organic Electronics group at IT. The consortium involves the IT branches of Lisbon and Coimbra, the CICECO – Aveiro Institute of Materials of the University of Aveiro and the Instituto de Física dos Materiais of the University of Porto.
INNOVATE is funded by the Fundação para a Ciência e Tecnologia (FCT) and, in its second year,already has major results published in Science Advances, Scientific Reports and IEEE sensors journal.
