TCP

A new engineering write-up describes a method for routing large language model requests across multiple inference providers using congestion-control ideas borrowed from TCP. The approach adaptively shifts traffic toward providers with lower latency or higher throughput, easing bottlenecks when one provider slows down. Commenters are discussing the trade-offs of applying classic networking techniques to AI serving infrastructure.

A new write-up explores running PostgreSQL over the QUIC protocol instead of the usual TCP connection. QUIC, developed originally at Google and standardized by the IETF, promises faster connection setup, built-in encryption and better performance on unreliable networks. The project is drawing attention from database and infrastructure developers curious whether these transport-layer gains translate into real-world improvements for database traffic.

A new vulnerability, CVE-2026-42542 with a CVSS score of 7.5, has been disclosed in TDengine, an open-source time-series database used in OT and IoT deployments. The flaw is an integer underflow in pre-authentication RPC message parsing: a single crafted packet sent to TCP port 6030 can crash unauthenticated servers. Versions 3.4.0.0 through 3.4.1.5 are affected, with a fix released in version 3.4.1.6. No exploitation in the wild has been reported so far, and a proof-of-concept has been withheld.
