The “TL;DR” for those who are interested is that this solution bypasses the normal iptables layer involved in most Kubernetes implementations to load balance traffic directly to Pods in the cluster. Servers/Hardware. Virtualization. Unfortunately, this appears to be GKE-specific. Nothing this time around.

Erik Smith, notably known for his outstanding posts on storage and FCoE, takes a stab at describing some of the differences between SDN and network virtualization in this post. Servers/Hardware. Virtualization. Only a true geek would be interested in this, but here’s some information on running OpenBSD in KVM on Linux.

Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). and their product (VirTool Network Analyzer) is aimed at providing some operational visibility into OpenStack virtual networks. Servers/Hardware. Virtualization. Here’s hoping you find something useful!

Open Virtual Network (OVN) is really ramping up and getting lots of attention, which I personally think is absolutely well-deserved. Servers/Hardware. Virtualization. Welcome to Technology Short Take #56! In this post, I’ve collected a few links on various data center technologies, news, events, and trends. Networking.

Recep will cover the hardware side of ONP; Gershon will cover the software side of ONP (referred to as ONS). The first concept that Recep discusses is network virtualization. He believes that network virtualization is primarily about decoupling network services from the underlying network infrastructure.

First up is Brent Salisbury’s how to build an SDN lab without needing OpenFlow hardware. Not unsurprisingly, one of the key advantages of STT that’s highlighted is its improved performance due to TSO support in NIC hardware. Servers/Hardware. Virtualization. I needed to fill in some other knowledge gaps first.)

A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB). Visit the site for more information on virtualization, servers, storage, and other enterprise technologies.

tech preview of virtual networks for Docker. Tom’s key point is that disaggregating software from hardware—which is kind of a given if you’re buying whitebox networking gear—gives you the (potential) flexibility to repurpose network gear based on the software running on it. Servers/Hardware. Virtualization.
