The field of network research is moving towards more accurate and dynamic emulation of complex networks, such as satellite networks and 5G user planes. This is driven by the need for more realistic testing and evaluation of network protocols and applications. Recent work has focused on developing new approaches to network emulation, including the use of trace-driven emulation and dynamic network emulation. Additionally, there is a growing emphasis on ensuring high-quality service (QoS) in 5G and beyond networks, with researchers exploring new methods for providing predictable behavior and fine-grained service differentiation. Noteworthy papers in this area include: TheaterQ, which presents a Linux qdisc for dynamic network emulation, allowing for high-accuracy emulation of dynamic networks. Kestrel, a sketch-based telemetry system for 5G user planes that provides fine-grained visibility into key metric distributions at a fraction of the cost of per-packet postcards. The QoS-aware data plane model for programmable transport networks, which ensures per-flow bandwidth guarantees, sub-millisecond delay for delay-critical traffic, and resilience under congestion.
