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.

Are there caveats to using IPv6 Global Unicast Addresses (GUAs)? Are there caveats to using IPv6 Global Unicast Addresses (GUAs)? Today's IPv6 Buzz podcast answers these and other listener questions. Where does IPv6 fit in to the Zero Trust model of network security?

Remember PC-2 knows the MAC address of the PC-1 when responding to ARP Request, so ARP Response is NOT broadcast, it is Unicast communication between PC-2 and PC-1. PC-2 knows about the PC-1 MAC address from the SMAC value of the ARP request that it received from PC-1. PC-1 maps the IP address 1.1.1.2 with 0x4a::56.

Route Type 3: Broadcast, Unknown Unicast, and Multicast (BUM) traffic delivery via EVPN networks requires Type 3 routes. To guarantee that data packets take the most effective route through the network, each component makes a fine-grained contribution to the identification, routing, and segregation of traffic.

We implemented a scalable PTPv2 unicast PTP server in Go, which we named ptp4u , and open-sourced it on GitHub. The PTP network PTP protocol The PTP protocol supports the use of both unicast and multicast modes for the transmission of PTP messages.

Class D addresses are not used for standard unicast communication but rather for multicast transmission, allowing a single packet to visit multiple destinations. The first three bits of the first octet are 110, which limits the number of hosts per network but allows for many networks. Class D Address (Multicast) Range : 224.0.0.0
