I don’t think you’re going to move those volumes with Intel X86 chips. For example, AT&T’s Open Compute Project whitebox architecture is based on Broadcom Jericho2 processors, with aggregate on-chip throughput of 9.6 Tbps, and which support 24 ports at 400 Gbps each. This is where AT&T’s 5G slicing is taking place.
My point exactly. If much of the cloud-native is happening on servers with Intel chips, and part of the micro-services is to also provide data plane functionality at that level, I don't see how it can scale for legacy mobile operators. It might make sense for niche, start-up mobile operators with little-to-no traffic serving some unique case, but not the classics we have today. Now, if they are writing their own bits of code on or for white boxes based on Broadcom et al, not sure that falls in the realm of "micro-services with Kubernetes". But I could be wrong.
Intel has developed nothing like this, and has had to resort to acquisition of multi-chip solutions to get these speeds (e.g. its purchase of Barefoot Networks Tofino2 IP). The X86 architecture is too complex and carries too much non-network-related baggage to be a serious player in 5G slicing.
Which we, as network operators, can all agree on. But the 5G folk seem to have other ideas, so I just want to see what is actually truth, and what's noise. Mark.
