IEEE Standard for Local and metropolitan area networks — Time-Sensitive Networking for Fronthaul
| Published By | Publication Date | Number of Pages |
| IEEE | 2018 | 62 |
New IEEE Standard – Active. This standard defines profiles that select features, options, configurations, defaults, protocols, and procedures of bridges, stations, and LANs that are necessary to build networks that are capable of transporting fronthaul streams, which are time sensitive.
