Forwarding Paradigm Matters: A Controlled Empirical Comparison of IPv6/MPLS and SRv6 for 5G eMBB and URLLC Transport Networks

This study empirically demonstrates that while both IPv6/MPLS and SRv6 forwarding architectures meet 5G transport requirements under steady-state conditions, SRv6's source-based routing exhibits distinct performance characteristics in jitter and worst-case latency compared to destination-based routing under burst-load scenarios typical of eMBB and URLLC traffic.

Numerical Simulation of Microscopic Oil-Water Two-Phase Flow Mechanisms in Porous Media Using the Volume of Fluid (VOF) Method

This study employs the Volume of Fluid (VOF) method to simulate pore-scale oil-water two-phase flow in porous media, revealing that injection velocity, wettability, and pore structure collectively govern displacement mechanisms and demonstrating that periodic intermittent and variable-rate injection schedules significantly enhance oil recovery efficiency while reducing cumulative water requirements compared to constant-rate injection.
