Juniper aims at simplifying campus fabric deployment

Juniper Networks is looking to ease complicated campus networking by automatically configuring and helping manage Ethernet VPN-Virtual Extensible XLAN (EVPN/VXLAN) deployments.Juniper also expanded its EX family of switches aimed at campus distribution deployments and low-density data-center top-of-rack environments, according to Jeff Aaron, vice president of enterprise marketing for Juniper.Juniper has rolled out a process called campus fabric workflow, under its subscription-based Wired Assurance program. Campus fabric workflow can help customers deploy common standards-based campus fabrics, such as EVPN multihoming, EVPN core/distribution and IP Clos for VLAN extensions with an easy process that lets them pick their desired topology, assign devices/roles and push configurations, Aaron said.To read this article in full, please click here

New Zero Trust navigation coming soon (and we need your feedback)

On March 20, 2023, we will be launching an updated navigation in the Zero Trust dashboard, offering all of our Zero Trust users a more seamless experience across Cloudflare as a whole. This change will allow you to more easily manage your Zero Trust organization alongside your application and network services, developer tools, and more.

As part of this upcoming release, you will see three key changes:

Quicker navigation

Instead of opening another window or typing in a URL, you can go back to the Cloudflare dashboard in one click.

Why we’re updating the Zero Trust navigation

In 2020, Gateway was broadly released as the first Cloudflare product that didn’t require a site hosted on Cloudflare’s infrastructure. In other words, Gateway was unconstrained by the site-specific model most other Cloudflare products relied on at the time, while also used in close conjunction with Access. And so, the Cloudflare for Teams dashboard was built on a new model, designed from Continue reading

The White House’s National Cybersecurity Strategy asks the private sector to step up to fight cyber attacks. Cloudflare is ready

The White House’s National Cybersecurity Strategy asks the private sector to step up to fight cyber attacks. Cloudflare is ready

On Thursday, March 2, 2023, the Biden-Harris Administration released the National Cybersecurity Strategy aimed at securing the Internet. Cloudflare welcomes the Strategy, and congratulates the White House on this comprehensive, much-needed policy initiative. The goal of the Strategy is to make the digital ecosystem defensible, resistant, and values-aligned. This is a goal that Cloudflare fully supports. The Strategy recognizes the vital role that the private sector has to play in defending the United States against cyber attacks.

The Strategy aims to make a fundamental shift and transformation of roles, responsibilities, and resources in cyberspace by (1) rebalancing the responsibility to defend cyberspace by shifting the burden away from individuals, small businesses, and local governments, and onto organizations that are most capable and best-positioned to reduce risks, like data holders and technology providers; and (2) realigning incentives to favor long-term investments by balancing defending the United States against urgent threats today and simultaneously investing in a resilient future. The Strategy envisions attaining these goals through five collaborative pillars:

  • Pillar One: defending critical infrastructure;
  • Pillar Two: disrupting and dismantling threat actors;
  • Pillar Three: shaping market forces to drive security and resilience;
  • Pillar Four: investing in a resilient future; and
  • Pillar Five: forging Continue reading

Fortinet adds new security, management features to its SASE platform

UNDER EMBARGO UNTIL TUESDAY, MARCH 7 AT 9AM ETFortinet has added features that broaden the range of management and security tools for its secure access service edge (SASE) package.The company has exanded its Secure Private Access offering that ties SASE resources together with SD-WAN-based applications through a Fortinet SD-WAN hub located in a nearby point-of-presence (PoP). The idea is to support larger hybrid environments and simplify anywhere access to corporate applications, said Nirav Shah, vice president of products with Fortinet.To read this article in full, please click here

Keeping the Cloudflare API ‘all green’ using Python-based testing

Keeping the Cloudflare API 'all green' using Python-based testing
Keeping the Cloudflare API 'all green' using Python-based testing

At Cloudflare, we reuse existing core systems to power multiple products and testing of these core systems is essential. In particular, we require being able to have a wide and thorough visibility of our live APIs’ behaviors. We want to be able to detect regressions, prevent incidents and maintain healthy APIs. That is why we built Scout.

Scout is an automated system periodically running Python tests verifying the end to end behavior of our APIs. Scout allows us to evaluate APIs in production-like environments and thus ensures we can green light a production deployment while also monitoring the behavior of APIs in production.

Why Scout?

Before Scout, we were using an automated test system leveraging the Robot Framework. This older system was limiting our testing capabilities. In fact, we could not easily match json responses against keys we were looking for. We would abandon covering different behaviors of our APIs as it was impossible to decide on which resources a given test suite would run. Two different test suites would create false negatives as they were running on the same account.

Regarding schema validation, only API responses were validated against a json schema and tests would not fail if the Continue reading

Dynamic MAC Learning: Hardware or CPU Activity?

An ipSpace.net subscriber sent me a question along the lines of “does it matter that EVPN uses BGP to implement dynamic MAC learning whereas in traditional switching that’s done in hardware?” Before going into those details, I wanted to establish the baseline: is dynamic MAC learning really implemented in hardware?

Hardware-based switching solutions usually use a hash table to implement MAC address lookups. The above question should thus be rephrased as is it possible to update the MAC hash table in hardware without punting the packet to the CPU? One would expect high-end (expensive) hardware to be able do it, while low-cost hardware would depend on the CPU. It turns out the reality is way more complex than that.

Artificial intelligence helps solve networking problems

With the public release of ChatGPT and Microsoft’s $10-billion investment into OpenAI, artificial intelligence (AI) is quickly gaining mainstream acceptance. For enterprise networking professionals, this means there is a very real possibility that AI traffic will affect their networks in major ways, both positive and negative.As AI becomes a core feature in mission-critical software, how should network teams and networking professionals adjust to stay ahead of the trend?Andrew Coward, GM of Software Defined Networking at IBM, argues that the enterprise has already lost control of its networks. The shift to the cloud has left the traditional enterprise network stranded, and AI and automation are required if enterprises hope to regain control.To read this article in full, please click here

Building your personal Linux cheat sheets

An Economic Perspective on Internet Centrality

What sustains a digital monopoly in today's world? It's not the amassing of a huge workforce, or even having access to large pool of capital. It's not even the use of proprietary technologies that are not accessible to others. So why isn't the Internet fulfilling its vision of profound and intense competitive pressure in every part of the digital supply chain? Whjat is sustaining the domination of the digital world by a select group of behemoths? And, can we change this picture?

IDC: Add used IT gear to the mix to stretch budgets, support sustainability

Reducing e-waste and extending the useful life of IT gear are top recycling drivers, according to an IDC survey.The most commonly cited motivation was to reduce e-waste, with more than half those surveyed in Latin America, Western Europe, and Asia-Pacific, citing it, and with US respondents falling just shy of 50%. The IDC Spotlight survey results of 540 respondents was conducted in February 2023 and written by IDC Research Vice President, Flexible Consumption and Financing Strategies for IT Infrastructure.To read this article in full, please click here
