Computer Science > Networking and Internet Architecture Title:Will there be a 7G? View PDF HTML (experimental) Abstract:The transition from 5G to 6G is becoming concrete: the ITU-R IMT-2030 framework has established the high-level vision and capability set for 6G, while 3GPP Release 21 has defined the path toward the first 6G specifications. This raises a deliberately provocative ques…

Networks have always been driven by the need for more speed and bandwidth, and in the AI era, that drive is accelerating the path to 1.6 terabit network connectivity. Work on 1.6T began in 2020 and became a formal IEEE study group in 2021, before AI was the industry’s dominant discussion point. That work became the IEEE P802.3dj Task Force, which has been building out the specifications that are …

The Problem You're debugging a connectivity issue. ping works fine, but curl times out. The usual approach: Run traceroute with ICMP - looks fine Run traceroute with TCP - dies at hop 6 Manually compare each hop Finally identify the firewall/ACL What if you could see this in one command? Protocol Divergence Localization I added this feature to multiprobe , a Rust network probing library. It runs …

DTLS Listeners add TLS-style encryption and authentication to UDP applications without changing the datagram transport model. Clients establish a DTLS 1.2 or DTLS 1.3 session with the Listener's assigned domain and port. Proxylity decrypts authenticated application data and delivers the plaintext payload to your configured Destinations. Responses from your application are encrypted and sent back …

Software-defined networking (SDN) and virtual networking have long been part of VMware’s portfolio, notably with the NSX technology that’s a foundational part of VMware Cloud Foundation (VCF). In 2025, VCF 9.0 expanded the networking capabilities with a public-cloud-style virtual private cloud model on top of that NSX foundation. The model gives tenants and VPC admins a simpler consumption layer …

If you ask most people where to start in DevOps or cloud engineering, you'll get answers like "learn Docker" or "get AWS certified." Almost nobody says "learn networking first," and that's a mistake — because every one of those tools sits directly on top of networking concepts, and skipping it means you're memorizing commands without understanding what they actually do. I hit this wall myself. I …
