=== Ethernet over InfiniBand ===

Ethernet over InfiniBand, abbreviated to EoIB, is an Ethernet implementation over the InfiniBand protocol and connector technology.
EoIB enables multiple Ethernet [[Bandwidth (computing)|bandwidths]] varying on the InfiniBand (IB) version.<ref>{{cite web|title=10 Advantages of InfiniBand | url=https://www.naddod.com/blog/top-10-advantages-of-infiniband |website=NADDOD|access-date=January 28, 2023}}</ref>
Ethernet's implementation of the [[Internet Protocol Suite]], usually referred to as TCP/IP, is different in some details compared to the direct InfiniBand protocol in IP over IB (IPoIB).
