PCF

2020 · 24 citations

Recently, traffic engineering mechanisms have been developed that guarantee that a network (cloud provider WAN, or ISP) does not experience congestion under failures. In this paper, we show that existing congestion-free mechanisms, notably FFC, achieve performance far short of the network's intrinsic capability. We propose PCF, a set of novel congestion-free mechanisms to bridge this gap. PCF achieves these goals by better modeling network structure, and by carefully enhancing the flexibility of…

Cogeneration Improves Separation Efficiency

Industrial & Engineering Chemistry Research · 2024-10-18 · 10 citations

For most distillation systems, the heat pump (HP) compressor, upgrading the heat from the condenser’s lower temperature to the reboiler’s higher temperature, uses electrical energy that is only a fraction of the reboiler heat, thereby making such processes highly efficient. However, the electricity utilized to power the HP compressor is typically dissipated as waste heat in cooling water. Here, we propose a novel strategy termed “Separation Cogeneration” whereby most of the electrical energy sup…

Transferable Neural WAN TE for Changing Topologies

2024-07-31 · 7 citations

Recently, researchers have proposed ML-driven traffic engineering (TE) schemes where a neural network model is used to produce TE decisions in lieu of conventional optimization solvers. Unfortunately existing ML-based TE schemes are not explicitly designed to be robust to topology changes that may occur due to WAN evolution, failures or planned maintenance. In this paper, we present HARP, a neural model for TE explicitly capable of handling variations in topology including those not observed in…
