IEEE 1588 v2.1 PTP Solution
Timestamping Unit IP & Software Stack
Overview
Comcores IEEE 1588 Precision Time Protocol (PTP) Solution is a high quality and high performance time synchronization solution, including Timestamping Unit IP (TSU) and PTP Software Stack. The PTP solution is fully compliant with IEEE 1588 v2.1 and IEEE 1588 v2 standards and enables time synchronization across multiple devices. The solution supports IEEE 802.1AS profile making it ideal for TSN applications. Comcores timing solution supports IEEE 1588 PTP profiles such as IEEE Default and Peer-to-Peer, as well as ITU-T G.8275.1 and ITU-T G.8275.2 profiles.
The fully autonomously operated IP includes XGMII and GMII interfaces. User configuration allows easy configuration for various synchronization methods.
Time synchronization is crucial in many applications and industries, such as Wireless, Aerospace, Automotive, Industrial, and many others. Phase alignment method allows sub-nanosecond precision and enables even the most demanding applications, for example, 5G networks (Delivering timing accuracy in 5G networks whitepaper).

O-RAN Fronthaul Security using MACsec
WHITEPAPER 5G is now in full deployment with numerous services available across the globe, especially for time-sensitive applications. 5G provides a range of improvements over existing 4G Long-Term Evolution (LTE) mobile networks with regard to capacity, speed and latency. It also provides better security. Nevertheless, security risks still remain and these need to be addressed quickly to ensure that 5G can address all of the target applications that drove original specifications. One of the...
MACsec for Deterministic Ethernet applications
WHITEPAPER MACsec provides authentication by ensuring that only known nodes are allowed to communicate on the LAN. It provides confidentiality through encryption of the data so only end-points with the correct encryption key can see the contents. Integrity is provided through mechanisms that can detect any interference with data in motion. MACsec operates at the data link layer acting as a client of the Ethernet Media Access Control. While the ability of MACsec to scale to high speeds is...

Daniel Dik Sep 14 2022 5G provides a range of improvements compared to existing 4G LTE mobile networks in regards to capacity, speed, latency and security. One of the main improvements is in the 5G RAN; it is based on a virtualized architecture where functions can be centralized close to the 5G core for economy or distributed as close to the edge as possible for lower latency performance. The functional split options for the baseband station processing chain results in a separation between...
