Cisco targets hyperscalers with silicon, high-end routers

Cisco says it wants to change the future of the Internet and has rolled out the new silicon, hardware and software it says will move toward that goal.The centerpiece of Cisco’s strategy revolves around its custom Silicon One chip technology and new Cisco 8000 Series carrier-class routers built on that silicon, which the company says has been in development for more than five years, at a cost of over $1 billion. The 8000s feature a new operating system – IOS XR7 that runs the boxes and handles security.Network pros react to new Cisco certification curriculum The Cisco Silicon One Q100 optical-routing silicon brings up to 10Tbps of network bandwidth in its first iteration – with a future goal of 25Tbps – and support for large non-blocking distributed routers, deep buffering with rich QoS and programmable forwarding. To read this article in full, please click here

What’s hot at the edge for 2020? Everything

Few areas of the enterprise face as much churn as the edge of the network.  Experts say a variety of challenges drive this change – from increased SD-WAN access demand to cloud interconnected resources and IoT, the traditional perimeter of the enterprise is shifting radically and will continue to do so throughout 2020.One indicator: Gartner research that says by 2023, more than 50% of enterprise-generated data will be created and processed outside the data center or cloud, up from less than 10% in 2019.To read this article in full, please click here

Celebrating a Successful Chapterthon 2019!

We are incredibly inspired by the collaborative projects brought to life by our Chapters for the 2019 Chapterthon, the global contest in which Internet Society Chapters develop a project within a set timeline and budget to achieve a common goal for the development of the Internet. This year’s theme was “Connecting the Unconnected” – because every last person on the planet is part of having an Internet for “everyone”, and we won’t rest until each person has the option of choosing to be connected.

Internet Society Chapters from all corners of the world developed innovative solutions that will continue to serve as inspiration for communities everywhere working to connect the unconnected. At the end of the contest, each project presented a three-minute video about the project specifics and its benefits to the community. Winning projects received a prize.

See how they addressed this global issue through local community initiatives!

Announcing the Winners!

1st Prize (USD 3000)

IPv6 Buzz 041: IPv4 Address Exhaustion And You!

The Regional Internet Registry for Europe (RIPE) recently announced its supply of public IPv4 addresses was officially depleted. In today's IPv6 Buzz podcast, we discuss what that means and why it's impactful for companies everywhere. We also discuss the history of IPv4 address exhaustion and why IPv6 is key to avoiding or mitigating the negative effects.

How we used our new GraphQL Analytics API to build Firewall Analytics

Firewall Analytics is the first product in the Cloudflare dashboard to utilize the new GraphQL Analytics API. All Cloudflare dashboard products are built using the same public APIs that we provide to our customers, allowing us to understand the challenges they face when interfacing with our APIs. This parity helps us build and shape our products, most recently the new GraphQL Analytics API that we’re thrilled to release today.

By defining the data we want, along with the response format, our GraphQL Analytics API has enabled us to prototype new functionality and iterate quickly from our beta user feedback. It is helping us deliver more insightful analytics tools within the Cloudflare dashboard to our customers.

Our user research and testing for Firewall Analytics surfaced common use cases in our customers' workflow:

• Identifying spikes in firewall activity over time
• Understanding the common attributes of threats
• Drilling down into granular details of an individual event to identify potential false positives

We can address all of these use cases using our new GraphQL Analytics API.

GraphQL Basics

Before we look into how to address each of these use cases, let's take a look at the format of a GraphQL query and how our Continue reading

Introducing the GraphQL Analytics API: exactly the data you need, all in one place

Today we’re excited to announce a powerful and flexible new way to explore your Cloudflare metrics and logs, with an API conforming to the industry-standard GraphQL specification. With our new GraphQL Analytics API, all of your performance, security, and reliability data is available from one endpoint, and you can select exactly what you need, whether it’s one metric for one domain or multiple metrics aggregated for all of your domains. You can ask questions like “How many cached bytes have been returned for these three domains?” Or, “How many requests have all the domains under my account received?” Or even, “What effect did changing my firewall rule an hour ago have on the responses my users were seeing?”

The GraphQL standard also has strong community resources, from extensive documentation to front-end clients, making it easy to start creating simple queries and progress to building your own sophisticated analytics dashboards.

From many APIs...

Providing insights has always been a core part of Cloudflare’s offering. After all, by using Cloudflare, you’re relying on us for key parts of your infrastructure, and so we need to make sure you have the data to manage, monitor, and troubleshoot your website, Continue reading

You Don’t Need IP Renumbering for Disaster Recovery

This is a common objection I get when trying to persuade network architects they don’t need stretched VLANs (and IP subnets) to implement data center disaster recovery:

Changing IP addresses when activating DR is hard. You’d have to weigh the manageability of stretching L2 and protecting it, with the added complexity of breaking the two sites into separate domains [and subnets]. We all have apps with hardcoded IP’s, outdated IPAM’s, Firewall rules that need updating, etc.

Let’s get one thing straight: when you’re doing disaster recovery there are no live subnets, IP addresses or anything else along those lines. The disaster has struck, and your data center infrastructure is gone.

7 ways to remember Linux commands

Some Linux commands are very easy to remember. The names may have only a couple letters and they often relate directly to what you want to do – like cd for changing directories or pwd for displaying the present working directory. Others can be very difficult to remember, especially if what you want to do relies on using a series of options.So, let’s look at some commands and tricks that can help you remember commands that do just what you need them to do and that make issuing those commands so much easier.Use aliases The best way to nail down a complicated command is to turn it into an alias. Just take a command that works for you and assign it an easy name. In fact, there is nothing wrong with using the name of the command itself as the alias as long as this doesn’t interfere with other ways you might want to use that command. For example, grep and egrep are often aliased to include using color to highlight your search term.To read this article in full, please click here
