IP doesn't require new hardware because it's a lower layer. Transmission Control Protocol - TCP - is baked into the firmware of every client network interface

IP doesn't require new hardware because it's a lower layer.
Transmission Control Protocol - TCP - is baked into the firmware of every client network interface card, and I would suppose in almost all of the switches and routers of business infrastructure.
I have no idea what data centers use. Infiniband and similar things aren't TCP, I think.
- lizknope 7y agoInfiniband is a lower level than TCP. Infiniband is often used as a replacement for ethernet in a supercomputing cluster. If you wish you can run IP over Infiniband (IPoIB) but I think most people using Infiniband are running a lower latency protocol like RDMA https://wiki.archlinux.org/index.php/InfiniBand#TCP/IP_(IPoIB) https://wiki.archlinux.org/index.php/InfiniBand#TCP/IP_(IPoI...
- manigandham 7y agoIs IP not handled by network devices and firmware? If it's just software then why don't we have IPv6 everywhere already?
- watersb 7y agoJiggawatts' comment [0] reminds me that transit routers don't do transmission control.

Mostly harmless.
