Traditional iptables-based filtering introduces significant overhead in high-throughput environments. We are currently experimenting with eBPF (Extended Berkeley Packet Filter) to bypass the kernel network stack, allowing for programmable packet processing directly at the network driver level.

As we expand our global node coverage, the complexity of MPLS management has become a bottleneck. SRv6 simplifies the network by removing state from the core and encoding instructions directly into the IPv6 header. This entry discusses the impact on cross-border latency.

TCP Head-of-Line (HoL) blocking is the primary adversary of modern web performance. By shifting to UDP-based QUIC streams, we've observed improved resilience in lossy network environments (packet loss > 2%). This shift requires a fundamental rethink of congestion control algorithms like BBRv2.
