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. The exchange shown is one of many possible combinations.

CCNA: Address Resolution Protocol (ARP) In this article, we will talk about ARP that maps the layer 3 address to the layer 2 MAC address. This is similar to Address Resolution Protocol, which maps layer 3 IP addresses to the layer MAC addresses. CCNA RnS Article #28: Why Spanning Tree Protocol? IP address. with 0x4a::56.

Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. The journey to PTP has been years long, as we’ve had to rethink how both the timekeeping hardware and software operate within our servers and data centers.
