Why NPO Beats CPO for AI Data Center Scale‑up: Alibaba Cloud’s Dual‑Network Blueprint

Alibaba Cloud argues that while CPO (Co‑Packaged Optics) looks perfect on paper, its closed ecosystem and production delays make it impractical for today’s 100k‑GPU AI clusters, and proposes an open, dual‑network architecture—HPN for scale‑out and UPN for ultra‑low‑latency scale‑up—driving a realistic near‑term roadmap for optical interconnect.

The Ongoing IPv6 Transition: Challenges, Progress, and Future Outlook

Although IPv6, standardized in 1998, offers a 128‑bit address space, its global rollout remains sluggish—only about 40 % of users have IPv6, early tunneling methods proved unreliable, and NAT and CDNs lessen urgency—so experts predict a dual‑stack Internet persisting until roughly 2045, with a gradual shift toward a name‑centric architecture rather than a rapid replacement of IPv4.
