FlowTurbo: From Best-Effort to Hit-Driven MegaFlow Hardware Offloading in Open vSwitch

Offloading fast-path MegaFlows in Open vSwitch to hardware accelerators is a common approach for accelerating packet forwarding in modern cloud data centers. However, due to the limited capabilities of current hardware accelerators, existing solutions still rely on coarse-grained, best-effort offloading, which struggle...

BiCayley: Traffic-Aware 3-ISL Topology Optimization via Bipartite Cayley Graph

Low Earth Orbit (LEO) satellite constellations utilize Inter-Satellite Links (ISLs) to ensure global network connectivity. While the 4-ISL grid is a common academic assumption, operational reports from industry leaders like Starlink reveal a shift toward hardware-constrained 3-ISL configurations to optimize the trade-o...
