The main focus of the HPSR 2025 – the 26th edition of HPSR conference – will be to assess how breakthrough changes occurring to networks and telecom are affecting areas related to switching and routing, and communication networks in general. We are soliciting original and thought-provoking works on big data, data analytics, cloud services, and machine-learning techniques applied to networking and switching and routing. Works on autonomous networks, 5G and beyond, IoT, Industry 4.0, social networks, network, cybersecurity, virtualization, and other advanced topics are also welcome.
