VMware to Be Acquired by Broadcom in a $61 Billion Deal

Chipmaker VMware, which was viewed as an acquisition target for server and chip makers looking to grow in the growing data center infrastructure market. The deal, valued at $61 billion, provides a new home for VMware, which is a software technology provider with decades-long partnerships with server and chip makers that include Nvidia, AMD and Intel. VMware has been a free agent for a good part of the last decade and has been bounced around between multiple owners. according to chip research firm IC Insights. Broadcom’s core business is around wireless, networking, cable modem and infrastructure components, which accounted for 73% of the $8.1 billion in Continue reading

Boosting your cluster networking with the Calico VPP data plane (beta)!

This is a guest post from Nathan Skrzypczak at Cisco. Nathan is part of a team of external contributors to Calico Open Source that have been working on an integration between Calico Open Source and Cisco’s data plane technology, VPP, for the last year.

Calico v3.23 is out, and with it a lot of new features! This release marks a long-awaited milestone for me and my team, as it includes the Calico VPP data plane (beta). So now seems to be a good time to reflect on what this integration actually is, and why we built it.

The Calico VPP data plane is the fourth data plane option for Calico. Alongside the Linux kernel, eBPF data plane, and Windows kernel, you can now choose to have packet processing done in a userspace network stack: the Vector Packet Processor (VPP). This means the service load-balancing, NAT-ing of packets, encapsulation, encryption and policies will all run in a user-space application. It all seems mostly transparent from the user’s perspective, is seamless to enable, and enabling it allows access to a series of really interesting features.

Quick packets yields more throughput

The first thing the Calico VPP data plane aims to Continue reading

I’ll Be At Cisco Live US Las Vegas 2022. See You There?

I’m attending Cisco Live US 2022 in Las Vegas this June. I’ll be there on the Explorer Pass, crawling the World Of Solutions and chatting with anyone and everyone my introverted nature can handle. If you’ll be there and want to meet up, DM me on Twitter or ping me on LinkedIn.

I’m especially looking to connect with…

The networking & cloud community. Maybe you listen to a podcast I host or read something I wrote and want to meet up. Yup, I’m all for that. Let’s do it. I’m always looking for new podcast guests, so if you’ve got a story to tell or opinion to share, let’s discuss. No pressure, though. I’d be just as happy to shake hands bump air-gapped fists and make your acquaintance. 🤜💥🤛

Vendors with new shinies. Brief me on your latest and greatest. Show off your nifty thing.

Stealth companies getting close to launch. I focus on IT operations and infrastructure–networking and cloud especially. I’d like to hear about what you’re coming to market with.

Technology Short Take 155

Welcome to Technology Short Take #155, just in time for the 2022 Memorial Day holiday weekend! (Here in the US, at least.) I mean, don’t you want to spend this weekend catching up on some technology-related articles instead of cooking on the grill and gathering with friends and family? I certainly hope not! Still, for those who need a little technology fix over the weekend, hopefully I’ve included something useful in the list of articles below. Enjoy!

Networking

  • Isovalent—the company behind the Cilium project—has been talking a lot about how the use of eBPF will transform things, including the architecture of a service mesh. Along those lines, one of their latest articles discusses how to achieve identity-based mutual authentication leveraging eBPF. If I’m understanding the article correctly (and feel free to correct me if I am mistaken) it looks as if Cilium Service Mesh will leverage/does leverage a combination of certificate-based mTLS for identity at the workload level and node-based transport encryption (via WireGuard) for data confidentiality. Even though I know that the underlying mechanisms are different, subjectively this feels a lot like using tunnels to connect workloads on different compute nodes (i.e., network virtualization). Is the Continue reading

We rebuilt Cloudflare’s developer documentation – here’s what we learned

We rebuilt Cloudflare's developer documentation - here's what we learned
We rebuilt Cloudflare's developer documentation - here's what we learned

We recently updated developers.cloudflare.com, the Cloudflare Developers documentation website, to a new version of our custom documentation engine. This change consisted of a significant migration from Gatsby to Hugo and converged a collection of Workers Sites into a single Cloudflare Pages instance. Together, these updates brought developer experience, performance, and quality of life improvements for our engineers, technical writers, and product managers.

In this blog post, we’ll cover the history of Cloudflare’s developer docs, why we made this recent transition, and why we continue to dogfood Cloudflare’s products as we develop applications internally.

What are Cloudflare’s Developer Docs?

Cloudflare’s Developer Docs, which are open source on GitHub, comprise documentation for all of Cloudflare’s products. The documentation is written by technical writers, product managers, and engineers at Cloudflare. Like many open source projects, contributions to the docs happen via Pull Requests (PRs). At time of writing, we have 1,600 documentation pages and have accepted almost 4,000 PRs, both from Cloudflare employees and external contributors in our community.

The underlying documentation engine we’ve used to build these docs has changed multiple times over the years. Documentation sites are often built with static site generators and, at Cloudflare, we’ve Continue reading

EVPN-VXLAN Explainer 4 – Route Type Three and Auto-Discovery

EVPN-VXLAN Explainer 4 - Route Type Three and Auto-Discovery

In this post we will have a look at another EVPN Route Type, that being RT-3, which goes by the rather opaque name of 'Inclusive Multicast Ethernet Tag'; and look at how it is used to ensure EVPN peers flood traffic to those neighbours that need it.
Firstly, we'll look at EVPN packet forwarding to provide some context around why this Route Type is important, then we will dive into its details, with all the usual show commands, packet captures and plethora of RFC name drops.

EVPN Packet Forwarding

Let's start off by running through EVPN Packet forwarding, for that we need an example network.

Example Network

  • For this post, we'll use a slightly larger network, this time with three switches.
  • As shown in Figure 1 below, this consists of three Aruba 6300s, all configured for OSPF and EVPN.
  • To emulate customer workloads, I have a physical linux server attached to each 6300. I have configured the interconnecting port as a trunk to generate traffic in different VLANs.
  • Each node is configured with customer-faced VLAN 10, which is bound to VNI 1010.
  • However, only two of the three peers, 6300-1 and 6300-2, are configured with a second VLAN and VNI, Continue reading

Can Broadcom + VMware move enterprise networking forward?

Broadcom's planned acquisition of VMware could open opportunities to reach enterprise and telco companies alike with innovative technology.

Pros and Cons of Radio Networking

Radio networking is a wireless communication method that uses radio waves to connect devices. It is commonly used in computer networks, cell phone networks, and other devices that need to communicate wirelessly.

Radio networking is often used in situations where it is not possible or convenient to use wired networking, such as in mobile or portable applications. Radio networking can be either peer-to-peer or infrastructure. 

In peer-to-peer networking, each device acts as both a transmitter and receiver, and there is no central access point. Infrastructure networking uses one or more access points that act as repeaters, amplifiers, and signal boosters to extend the range of the network. 

Advantages of radio networking

Radio networking has many advantages over other types of wireless communication. It is very reliable and can work in a variety of environments. Radio networking is also very secure and can be encrypted to protect data. Radio networking is also very fast and can support high-speed data transfers.

Low start-up costs

One of the biggest advantages of radio networking is that it has very low start-up costs. All you need is a radio transmitter and receiver, and you can start communicating.

This makes radio networking ideal for Continue reading
