Ericsson Returns to Profit Amid Rising 5G Costs

Really Late Company Christmas Shopping

I’m headed out to Cisco Live Europe today, so I’m trying to get everything packed before I head to the airport. I also realize I need to go buy a few things for my suitcase. Which must be the same thing that a bunch of companies thought this week as they went on a buying spree! Seriously:

• VMware buys Nyansa for the VeloCloud unit
• Arista is going buy Big Switch Networks, as first reported by SDxCentral but pretty much what’s happening for sure.

I don’t think we’re quite done yet, either. An oblique tweet from a friend with some inside sources leads me to believe that the reason why this is happening right now is because some of the venture funds are getting antsy and are calling in their markers. Maybe they need the funds to cash out investors? Maybe they’re looking to reduce their exposure to other things? Maybe they’re ready to jump on a plane to an uncharted island somewhere?

This is one of the challenges when you’re beholden to investors. Sure, not all of us are independently wealthy and capable of bootstrapping our own startup. We need some kind of funding to make that happen. But Continue reading

A Look Back, Some Predictions, And Learning As Engineers

In this episode we sit down with Jed Casey and Bruno Wollmann to have a conversation about what’s top of mind. We take a quick look back at predominant trends in 2019, pull out the crystal ball and make some predictions for 2020, and discuss certifications and learning as engineers.

Video: FRRouting Architecture

After a brief overview of FRRouting suite Donald Sharp continued with a deep dive into FRR architecture, including the various routing daemons, role of Zebra and ZAPI, interface between RIB (Zebra) and FIB (Linux Kernel), sample data flow for route installation, and multi-threading in Zebra and BGP daemons.

Gartner: Data-center spending will inch up this year

Global IT spending could reach $3.865 trillion in 2020, up 3.4% over 2019, according to newly released data from IT research firm Gartner. In comparison, 2019 saw just 0.5% growth over 2018 levels. Spending is expected to continue to climb into 2021, surpassing the $4 trillion mark with 3.7% growth.Spending on hardware – including edge devices and data center hardware – will be deemphasized, while investments in software and services, including cloud, will see an increase, the firm predicts.

Network Simulations with Network Service Mesh

In September 2019 I had the honour to present at Open Networking Summit in Antwerp. My talk was about meshnet CNI plugin, k8s-topo orchestrator and how to use them for large-scale network simulations in Kubernetes. During the same conference, I attended a talk about Network Service Mesh and its new kernel-based forwarding dataplane which had a lot of similarities with the work that I’ve done for meshnet. Having had a chat with the presenters, we’ve decided that it would be interesting to try and implement a meshnet-like functionality with NSM. In this post, I’ll try to document some of the findings and results of my research.

Network Service Mesh Introduction

NSM is a CNCF project aimed at providing service mesh-like capabilities for L2/L3 traffic. In the context of Kubernetes, NSM’s role is to interconnect pods and setup the underlying forwarding, which involves creating new interfaces, allocating IPs and configuring pod’s routing table. The main use cases are cloud-native network functions (e.g. 5G), service function chaining and any containerised applications that may need to talk over non-standard protocols. Similar to traditional service meshes, the intended functionality is achieved by injecting sidecar containers that communicate with a distributed control plane of Continue reading

How Open-RAN could ‘white-box’ 5G

One of Britain’s principal mobile networks, O2, has just announced that it intends to deploy Open Radio Access Network technology (O-RAN) in places.O-RAN is a wireless industry initiative for designing and building radio network solutions using “a general-purpose, vendor-neutral hardware and software-defined technology,” explains Telecom Infra Project, the body responsible, on its website.TIP is the trade body that, along with Intel and Vodafone, conceived of the technology alternative – an attempt at toppling the dominance of Ericsson, Huawei and Nokia, which provide almost all mobile telco infrastructure now.To read this article in full, please click here
