Engineering at Meta
FEBRUARY 7, 2024
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. Complete trust in the validity of server timestamps.

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. Network card Our ultimate goal is to make protocols such as PTP propagate over the packet network. Every time-sensitive PTP packet gets hardware timestamped by the NIC.

An IP address is a unique identifier for a device on a network, enabling devices to communicate with each other using the Internet Protocol (IP). Class D addresses are not used for standard unicast communication but rather for multicast transmission, allowing a single packet to visit multiple destinations. What is an IP Address?
