Even if it just cheaper and same order of magnitude latency, it'll likely take over. High end systems would still have DRAM as a large L4/LLC cache, while low end ones will omit it.

The NOS was based on software written at Stanford. The HW was Andy Bechtolsheim 68K board, which also (without the theft) become the SUN-1. cisco paid Stanford off later, although the author of that NOS is still unhappy.

If your PC is faster than a certain speed Win95 won't boot. This bit us at VMware, since it was common to want to run old Win95-only software in a VM on fast machines. We ended up having the VMM (Virtual Machine Monitor) patch up the

Signal is open source, so you can just fork it to remove the dependency on GCM. In fact, someone already has, so you can just use it: https://fdroid.eutopia.cz/

Or start announcing more specific routes. If you have a /20, and some jackass starts announcing it, you announce 2 /21s instead. You're screwed if you only have a /24, though, since everyone will filter /25s.

Google has contributed ISIS and BGP code to Quagga in the past, as well as funding some testing at the OSRF. Presumably they use it in at least some parts of their operations.

I'd imagine Zuck is going along with it because WhatsApp announced that they were going to do this before the acquisition closed. Zuck is way too savvy to publicly reverse that announcement once the deal closed. Imagine how bad that w

The problem that resilient hashing solves is that if you have 8 LBs in an ECMP group, and one dies and gets withdrawn, a naive hash function would redistribute all flows randomly, meaning every active connection would break. Resilient hashi

We (Cumulus Networks) support a feature called "resilient hashing" that ensures that if a software LB fails, only the flows going to that LB are redistributed to the remaining LBs. You still lose some connections when an LB fails,

We (Cumulus Networks) have customers who use VXLAN for this type of tunneling. It is supported in modern Ethernet switch chips. They're doing basically what Google is, but with off the shelf hardware and a openly-buyable NOS.

Microsoft isn't a huge Debian fan, they just chose it because our (Cumulus) distribution is based on Debian, and so our patches are against it. Porting them to another distribution would be work.

We (Cumulus) have been involved in switchdev since the beginning. Over the long term, it will replace switchd in our products, but that is at least a year out, maybe two. - nolan co-founder, CTO @Cumulus

Raman amplifiers still require juice to run the pumping laser. There aren't exactly 110V sockets sitting on the ocean floor. There is a copper tube around the fiber bundle that carries high voltage (usually 10,000+ volts to reduce los

Intel used "iHDL" which was an in-house language from 1986 to 2005, and after 2005 switched mainly to Verilog. You usually see VHDL in .eu and some defense contractors, and Verilog everywhere else. VHDL feels similar to Ada, and

Netgear has a cheap 5 port switch (GS105e, IIRC) that can do VLANs and trunking. There also have larger models. You'd configure the switch port that the router is plugged into as a trunk, and then configure the other 4 switch ports as

You're probably tired of hearing this from me, but if you distribute the storage, you can evacuate all the VMs off a host, down it, do whatever, bring it back up, and then unevacuate.

None of the current forwarding ASIC vendors publish enough information to write a driver for their chips. So no, you can't write your own driver. The reason OpenSwitch's OpenNSL binary is binary-only is because it uses Broadcom&

They don't even need to go after the firmware: Openswitch has a binary-only userspace process that talks to the hardware. That is where a bad actor would hide something nefarious.

Containers (which are more than just cgroups) are supposed to be secure. In practice, the attack surface is much bigger for containers than VMs, so there are far more "break out of container" vulnerabilities out there than "b

Palo Alto Networks firewalls do exactly that. It was one of their big differentiating feature; this is the main reason companies buy them. Personally I agree with you, but PANW has 15.62 billion reasons to disagree with us. I suspect Goog

We at Cumulus have been told by our customers that having one of our rocket-turtle stickers on their laptop results in a much faster and easier negotiations about discounts with their Cisco sales rep. An Arista sticker probably works too.

amd64 supports a separate interrupt stack (up to 8, IIRC), which would allow you to continue using the redzone optimization.

Note that OpenSwitch and Cumulus Linux are both exactly the same in terms of Open Source: everything is Open Source except the part that talks to the ASIC. OpenNSL in OpenSwitch's case, and switchd in Cumulus's case. <disclaim
