Déjà vu for Advanced Switching

Well, not exactly. Intel washed its hands of an effort to tailor PCI Express for the comms market, and they don't seem to be revisiting that decision.

However, as part of a deal selling off its IXP network processor technology to Netronome, Intel did make a point of insisting the startup adopt Intel's upcoming Quick Path Interconnect (QPI) for its next-generation IXP-based processors. QPI is Intel's answer to AMD's HyperTransport, a 6.4 Gbytes/s link replacing the Intel front-side bus in CPUs starting with the Nehalem generation in late 2008.

Don't expect QPI to try to replace tried-and-true network processor interfaces such as the SPI 4.2. It probably won't even give Interlaken, Cisco's proprietary interconnect, much of a run for its money. Nevertheless, Intel will leverage the link to try to get more design wins for x86 and IXP parts in comms.

You probably meant "GBytes/s" instead of "Mbytes/s"

Speaking of standards that no one uses, any thoughts on Tundra's latest downsizing? RapidIO not exactly blowing the doors off?
