VMware’s Project Monterey creates a virtual environment to run applications and services on Data Processing Units (DPUs). VMware is partnering with multiple server OEMs and DPU vendors to bring Project Monterey to distributed infrastructure. In this video, Drew Conry-Murray from the Packet Pushers is joined by VMware’s Paul Turner, Vice President Product Management vSphere. We […]

The Internet has become a significant factor in geopolitical conflicts, such as the ongoing war in Ukraine. Tomorrow marks one year since the Russian invasion of that country. This post reports on Internet insights and discusses how Ukraine's Internet remained resilient in spite of dozens of disruptions in three different stages of the conflict.
Key takeaways:
VNets and VPN/ExpressRoute connections are associated with vHub’s Default Route Table, which allows both VNet-to-VNet and VNet-to-Remote Site IP connectivity. This chapter explains how we can isolate vnet-swe3 from vnet-swe1 and vnet-swe2 using VNet-specific vHub Route Tables (RT), still allowing VNet-to-VPN Site connection. As a first step, we create a Route Table rt-swe12 to which we associate VNets vnet-swe1 and vnet-swe2. Next, we deploy a Route Table rt-swe3 for vnet-swe3. Then we propagate routes from these RTs to Default RT but not from rt-swe12 to rt-swe3 and vice versa. Our VPN Gateway is associated with the Default RT, and the route to remote site subnet 10.11.11.0/24 is installed into the Default RT. To achieve bi-directional IP connectivity, we also propagate routes from the Default RT to rt-swe-12 and rt-swe3. As the last step, we verify both Control Plane operation and Data Plane connections.

Today's podcast episode revisits the subject of IPv6 address allocation along with how changes in network planning and Regional Internet Registry (RIR) policy are influencing allocation size requests. We also look at how network trends around IoT, cloud, and SD-WAN might affect allocation size and how to overcome "IPv4 thinking."

One of my readers sent me a question along these lines:
How do we determine the number of spines needed in a leaf-and-spine fabric? It’s easy to calculate the number of leaf nodes from the required number of server ports, and two spines give you the redundancy. Does it make sense to have more spines if two are good enough from the capacity perspective?
There are at least two factors to consider:

For last week’s show, we had Christopher Wood on to talk about oDoH. This week, Chris joins us again to talk about Multiplexed Application Substrate over QUIC Encryption, or masque, which is a more generalized privacy proxy. You can find more about masque at the IETF WG page.
With the release of ChatGPT as a product, Microsoft brought Machine Learning (ML) and Artificial Intelligence (AI) back into focus for millions of users—including network operators, coders, and other folks in information technology. People are once against asking if this technology will make them redundant or how it might change their day-to-day jobs. As always, […]

This video looks at the fundamentals of Data Processing Units (DPUs) and what they can do with an eye toward helping network engineers and infrastructure professionals. Greg Ferro from the Packet Pushers and Joseph White, a Fellow at Dell Technologies, discuss how DPUs are different from GPUs and CPUs; using DPUs to offload workloads from […]
