![]() ![]() Our results are a first step in understanding the IPX Network at its core, key to fully understand the global mobile Internet. We shed light on the structure of the IPX Network as well as on the temporal, structural and geographic features of the IPX traffic. We analyze an operational dataset from a large IPX-P that includes BGP data as well as statistics from signaling. The IPX Network is a private network formed by a small set of tightly interconnected IPX-Ps. This paper presents the first characterization of this, so-far opaque, IPX ecosystem and a first-of-its-kind in-depth analysis of an IPX Provider (IPX-P). It forms the core that enables global data roaming while supporting emerging applications, from VoLTE and video streaming to IoT verticals. The IPX Network interconnects about 800 Mobile Network Operators (MNOs) worldwide and a range of other service providers (such as cloud and content providers). Thus, our research lays the foundation for making DNSSEC, and protocols with similar constraints ready for PQC.Ī. We show that three algorithms, partially, meet DNSSEC’s requirements but also show where and how we would still need to adapt DNSSEC. We evaluate current candidate PQC signature algorithms in the third round of the NIST competition on their suitability for use in DNSSEC. DNSSEC is particularly challenging to transition to PQC, since DNSSEC and its underlying transport protocols require small signatures and keys and efficient validation. In its main role, DNS translates human-readable domain names to IP addresses and DNSSEC guarantees message integrity and authenticity. In this paper we provide a case study, analyzing the impact of PQC on the Domain Name System (DNS) and its Security Extensions (DNSSEC). This means we cannot just replace existing algorithms by PQC alternatives, but need to evaluate if they meet the requirements of the Internet protocols that rely on them. They can have larger signatures or keys, and often require more computational power. These new algorithms differ significantly from current ones. More secure algorithms, colloquially referred to as Post-Quantum Cryptography (PQC), are under active development. Quantum computing is threatening current cryptography, especially the asymmetric algorithms used in many Internet protocols. Current limitations and future work are also included as part of the discussion section. Additionally, it provides an evaluation of the PD approach as well as the expected impact on K–12 STEM education. This paper describes the teachers’ PD program, the NGSS lessons created and the hardware and software system developed to support the initiative. ![]() The labs are also supported by Next Generation Science Standards (NGSS)-compliant teacher/student material. Specifically, since it is designed for use by non-technical middle and high school teachers/students, it adds easy-to-use enhancements to the experiments’ execution and the results visualization. The software executes and manages the experiments in the same operational philosophy as the COSMOS testbed. The labs run on the COSMOS Educational Toolkit, a hardware and software system that offers a large variety of pre-orchestrated K–12 educational labs. The COSMOS team has already conducted successful pilot summer programs for middle and high school STEM teachers, where the team worked with the teachers and jointly developed innovative real-world experiments that were organized as automated and repeatable math, science, and computer science labs to be used in the classroom. COSMOS’ approach for K–12 education is twofold: (i) create an innovative and concrete set of methods/tools that allow teaching STEM subjects using live experiments related to wireless networks/IoT/cloud, and (ii) enhance the professional development (PD) of K–12 teachers and collaborate with them to create hands-on educational material for the students. The COSMOS wireless research testbed is being deployed in West Harlem (New York City) as part of the NSF Platforms for Advanced Wireless Research (PAWR) program. This paper focuses on the educational activities of COSMOS – _C_loud enhanced _O_pen _S_oftware defined _MO_bile wireless testbed for city _S_cale deployment.
