“Network Programmability Framework for Vertical Applications in the Beyond 5G Era” Paper Presentation at EuCNC 2022

Harilaos Koumaras EVOLVED-5G technical manager presented the conference paper entitled “Network Programmability Framework for Vertical Applications in the Beyond 5G Era on June 9th 2022. Programmability in 5G Core (5GC) enables operators to open telecom network capabilities and services to third-party developers, allowing them to establish innovative network-aware vertical applications. This openness is materialized through the 5G Service Based Architecture (SBA) that exposes the network intelligence to the vertical applications through standardized Application Programming Interfaces (APIs). Building upon the application empowerment that the programmable APIs can offer unleashing new business potentials, the ecosystem of Network Applications (NetApps) emerges to stand as a facilitating middle-ware between the network and applications. This study presents the architectural and implementation aspects of an open all-encompassing framework for NetApps considering their entire spanning from their development to their final publication in the market.

Offering the 3GPP Common API Framework as Microservice to Vertical Industries” Paper Presentation at EuCNC 2022

Alejandro Molina Sanchez from Telefonica presented the EVOLVED-5G conference paper entitled “Offering the 3GPP Common API Framework as Microservice to Vertical Industries” on June 9th 2022. The 3GPP Common API Framework (CAPIF) has been standardized to guarantee a unique reference model for API-based service provisioning in 3GPP systems. The great potential of such framework is currently revealed due to the need for interaction between vertical industries and mobile networks. Towards realizing the above-mentioned interaction, we describe key functional aspects of CAPIF by focusing on related functional entities and APIs. In addition, we implemented the CAPIF Core Function, i.e., the main entity of CAPIF, as an effort to set the basis for an ecosystem where developers from vertical industries can easily develop network-interacting applications. To facilitate any further contribution in the area, our CAPIF implementation follows the principles of microservice programming, and it is released (open source) together with a set of evaluation tests.

EVOLVED-5G’s NetApp for Verticals Session in EuCNC 2022

Harilaos Koumaras EVOLVED-5G technical manager presented the nature and the NetApp architecture of the EVOLVED-5G in the NetApp for Verticals Session of EuCNC 2022 on June 8, 2022. The session focused on discussing how NetApp empowers the verticals on-boarding on 5G and reinforce the fact that 5G is a platform and not a pipe. Different actors from diverse vertical domains will share their design and their interaction with the 5G platform owner. Through this session, we target to capture the take of the community on the level of interaction and trust that NetApp should support, the way services are provided to verticals, how NetApp simplifies the implementation and deployment of vertical systems at large scale etc.

NEFSim: An Open Experimentation Framework Utilizing 3GPP’s Exposure Services” Paper Presentation at EuCNC 2022

Harilaos Koumaras (NCSR “DEMOKRITOS”) EVOLVED-5G’s Technical Manager presented the conference paper entitled “NEFSim: An Open Experimentation Framework Utilizing 3GPP’s Exposure Services” in the context of Session 8 of EUCNC 2022. Network Exposure Function (NEF) enables third-party application providers utilize the network capabilities and services that the 5G System offers. The 3rd Generation Partnership Project (3GPP) provides open standardized Application programming Interfaces (API) through NEF; however, a big gap appears in the market between mobile operators and service providers since no commercial solutions are available. In this context, the NEF’s standardized APIs offered by 3GPP are examined. As a result of this analysis an open-source simulator “NEFSim” is presented. NEFSim realizes the aspects of the NEF and enables application developers to experiment with the northbound APIs under a simulated, configurable environment. The paper has been created by Dimitrios Fragkos (National Centre for Scientific Research Demokritos (NCSRD) & University of Peloponnese, Greece), Georgios Makropoulos, Anastasios Gogos and Harilaos Koumaras (NCSR Demokritos, Greece), Alexandros Kaloxylos (University of Peloponnese, Greece & The 5GIA, Belgium).

“Implementation and evaluation of the Multi-connection Tactile Internet Protocol and API”

EVOLVED-5G partners from UMA submitted a conference paper entitled “Implementation and evaluation of the Multi-connection Tactile Internet Protocol and API” in the Next-Generation Tactile Internet (FlexNGIA 2022) of IEEE Communications Society. In this paper you may learn about how tactile Internet defines applications for remotely controlling and manipulating critical devices that require perceived real-time operation with additional demanding requirements like reliability. These use cases with stringent requirements demand adequate transport protocols to take advantage of the underlying possibilities. Traditional transport-layer solutions like TCP and UDP are no longer sufficient, hence novel protocols are being developed to support these applications. In this paper, we present an implementation and evaluation of the Multi-connection Tactile Internet Protocol (MTIP), a transport layer proposal to support these communications. MTIP uses application and network status information to perform an intelligent selection of paths in order to improve reliability and latency. In our evaluations, we study how the different configurations of the MTIP algorithm affect this selection and we see a direct trade-off where, with more restrictive thresholds, MTIP can increase the packets received correctly at the cost of sending extra duplicate packets.
