While deploying Precision Time Protocol (PTP) at Meta, we’ve developed a simplified version of the protocol (Simple Precision Time Protocol – SPTP), that can offer the same level of clock synchronization as unicast PTPv2 more reliably and with fewer resources. In our own tests, SPTP boasts comparable performance to PTP, but with significant improvements in [...] Read More...

Meta is transferring its IP for Evenstar, a program to accelerate the adoption of open RAN technologies, to the Open Compute Project (OCP). Meta will contribute Evenstar’s radio unit design to OCP, giving the telecom industry its first open, white box radio unit solution. The TIP Open RAN community will leverage the Evenstar radio unit [...] Read More...

When we first conceived of our aerial fiber deployment solution, Bombyx (the Latin name for a silk moth), we imagined a robot weaving strands of fiber-optic cables over powerlines, helping human workers quickly connect communities even in very rural or remote locations. Now, after years of successful research, Bombyx is taking the next steps in [...] Read More... The post Bombyx is being licensed for product development appeared first on Engineering at Meta.

What the research is:  Millisampler is one of Meta’s latest characterization tools and allows us to observe, characterize, and debug network performance at high-granularity timescales efficiently. This lightweight network traffic characterization tool for continual monitoring operates at fine, configurable timescales. It collects time series of ingress and egress traffic volumes, number of active flows, incoming [...] Read More...
