Gartner says IT spending to top $4 trillion in 2022

With IT budgets growing at the fastest rate in 10 years, worldwide IT spending is projected to total $4.5 trillion in 2022, an increase of 5.5% from 2021, according to the latest Gartner forecasts.All IT spending segments—from data-center systems to communications services—are forecast to grow next year, according to Gartner.  [Get regularly scheduled insights by signing up for Network World newsletters.] Enterprise software is likely to have the highest growth in 2022 at 11.5%, driven by infrastructure software spending. Global spending on devices grew over 15% as remote work, telehealth and remote learning took hold, and Gartner expects 2022 will continue that growth as enterprises upgrade devices and/or invest in multiple devices to support the hybrid work setting. “Enterprises will increasingly build new technologies and software, rather than buy and implement them, leading to overall slower spending levels in 2022 compared to 2021,” said John-David Lovelock, distinguished research vice president at Gartner.To read this article in full, please click here

MTU size issues, fragmentation, and jumbo frames

The maximum transmission unit (MTU) is the largest number of bytes an individual datagram can have without either being fragmented into smaller datagrams or being dropped along the path between its source and its destination.For Ethernet frames—and many other types of packets—that number is 1500 bytes, and it generally meets the requirements of traffic that can cross the public internet intact.[Get regularly scheduled insights by signing up for Network World newsletters.] So, if 2000-byte Ethernet packets arrive at a router, it will split their payloads in two and repackage them into two packets that are each smaller than 1500 bytes and so meet the MTU.To read this article in full, please click here

Hedge 105: Johan Gustawsson and Changing Provider Architectures

Many service providers have the feeling that they “didn’t do anything wrong, but somehow we still lost.” How are providers reacting to the massive changes in the networking field, and how are they trying to regain their footing so they can move into the coming decades better positioned to compete? Join Johan Gustawsson, Tom Ammon, and Russ White as we discuss the impact of merchant silicon and changing applications on the architecture of service providers.

Traffic Sequence: Which Product Runs First?

Traffic Sequence: Which Product Runs First?
Traffic Sequence: Which Product Runs First?

“Which came first, the chicken or the egg?” It’s one of life's great questions. There are hundreds of articles published which conclude with eggs predating chickens by millions of years. Unfortunately, Cloudflare users don't have New Scientist on hand to answer similar questions.

Which runs first, Firewall Rules or Workers? Page Rules or Transform Rules? Whilst not as philosophically challenging, the answers to these questions are key to setting up your Cloudflare zone correctly. Answering them has become increasingly difficult as more and more functionality is added, thanks to our incredible rate of shipping products. What was once a relatively easy to understand traffic flow exploded in complexity with the introduction of products such as Workers, Load Balancing Rules and Transform Rules. And this big bang of product announcements is only accelerating each year.

To begin addressing this problem, we developed Traffic Sequence. Traffic Sequence is a simple dashboard illustration which shows a default, high-level overview of how Cloudflare products interact. Think of this as your atlas, rather than your black cab driver’s “Knowledge”. This helps you understand that London is in the south east of the UK, but not that it's quicker to walk than use Continue reading

Telegraf sFlow input plugin

The Telegraf agent is bundled with an SFlow Input Plugin for importing sFlow telemetry into the InfluxDB time series database. However, the plugin has major caveats that severely limit the value that can be derived from sFlow telemetry.

Currently only Flow Samples of Ethernet / IPv4 & IPv4 TCP & UDP headers are turned into metrics. Counters and other header samples are ignored.

Series Cardinality Warning

This plugin may produce a high number of series which, when not controlled for, will cause high load on your database.

InfluxDB 2.0 released describes how to use sFlow-RT to convert sFlow telemetry into useful InfluxDB metrics.

Using sFlow-RT overcomes the limitations of the Telegraf sFlow Input Plugin, making it possible to fully realize the value of sFlow monitoring:

  • Counters are a major component of sFlow, efficiently streaming detailed network counters that would otherwise need to be polled via SNMP. Counter telemetry is ingested by sFlow-RT and used to compute an extensive set of Metrics that can be imported into InfluxDB.
  • Flow Samples are fully decoded by sFlow-RT, yielding visibility that extends beyond the basic Ethernet / IPv4 / TCP / UDP header metrics supported by the Telegraf plugin to include ARP, ICMP, Continue reading

Getting Cloudflare Tunnels to connect to the Cloudflare Network with QUIC

Getting Cloudflare Tunnels to connect to the Cloudflare Network with QUIC

I work on Cloudflare Tunnel, which lets customers quickly connect their private services and networks through the Cloudflare network without having to expose their public IPs or ports through their firewall. Tunnel is managed for users by cloudflared, a tool that runs on the same network as the private services. It proxies traffic for these services via Cloudflare, and users can then access these services securely through the Cloudflare network.

Recently, I was trying to get Cloudflare Tunnel to connect to the Cloudflare network using a UDP protocol, QUIC. While doing this, I ran into an interesting connectivity problem unique to UDP. In this post I will talk about how I went about debugging this connectivity issue beyond the land of firewalls, and how some interesting differences between UDP and TCP came into play when sending network packets.

How does Cloudflare Tunnel work?

Getting Cloudflare Tunnels to connect to the Cloudflare Network with QUIC

cloudflared works by opening several connections to different servers on the Cloudflare edge. Currently, these are long-lived TCP-based connections proxied over HTTP/2 frames. When Cloudflare receives a request to a hostname, it is proxied through these connections to the local service behind cloudflared.

While our HTTP/2 protocol mode works great, we’d like to improve a Continue reading

Arm creates virtual IoT chips to accelerate development

It can take years for a CPU to go from design to silicon, so Arm is helping developers get a jump on things by putting virtual models of its chip designs in the cloud. The virtual models will allow developers to write and test applications before the actual silicon ships.Dubbed Arm Total Solutions for IoT, the project is a full-stack solution intended for Internet of Things applications and use cases. Arm says the early access for developers, OEMs and service providers, as well as the reduction in product design cycles, could accelerate deployments by up to two years.Arm doesn’t make chips the way Intel and AMD do. It makes designs and licenses them to more than 800 OEMs, which are responsible for everything from embedded devices to servers. Once Arm releases the basic chip design to its partners, the partners then add their own IP to differentiate from the competition, which takes time.To read this article in full, please click here
