Juniper targets data-center management with Apstra upgrade

Juniper Networks is giving its Apstra software a boost with management features designed to make complicated data centers easier to operate. The vendor rolled out Apstra 4.2.0, which includes intent-based analytics probes for telemetry and network visibility as well as support for HashiCorp’s Terraform network provisioning tool.Since it bought Apstra in 2021, Juniper has been bolstering the platform with features such as automation, intelligent configuration capabilities, multivendor hardware and software support, and improved environmental analytics, with the goal of making the system more attractive to a wider range of enterprise data-center organizations.To read this article in full, please click here

How Waiting Room makes queueing decisions on Cloudflare’s highly distributed network

How Waiting Room makes queueing decisions on Cloudflare's highly distributed network
How Waiting Room makes queueing decisions on Cloudflare's highly distributed network

Almost three years ago, we launched Cloudflare Waiting Room to protect our customers’ sites from overwhelming spikes in legitimate traffic that could bring down their sites. Waiting Room gives customers control over user experience even in times of high traffic by placing excess traffic in a customizable, on-brand waiting room, dynamically admitting users as spots become available on their sites. Since the launch of Waiting Room, we’ve continued to expand its functionality based on customer feedback with features like mobile app support, analytics, Waiting Room bypass rules, and more.

We love announcing new features and solving problems for our customers by expanding the capabilities of Waiting Room. But, today, we want to give you a behind the scenes look at how we have evolved the core mechanism of our product–namely, exactly how it kicks in to queue traffic in response to spikes.

How was the Waiting Room built, and what are the challenges?

The diagram below shows a quick overview of where the Waiting room sits when a customer enables it for their website.

Waiting Room is built on Workers that runs across a global network of Cloudflare data centers. The requests to a customer’s website can Continue reading

Addresses in a Networking Stack

After discussing names, addresses and routes, it’s time for the next question: what kinds of addresses do we need to make things work?

End-users (clients) are usually interested in a single thing: they want to reach the service they want to use. They don’t care about nodes, links, or anything else.

End-users might want to use friendly service names, but we already know we need addresses to make things work. We need application level service identifiers – something that identifies the services that the clients want to reach.

Simple or Complex?

A few weeks ago, Daniel posted a piece about using different underlay and overlay protocols in a data center fabric. He says:

There is nothing wrong with running BGP in the overlay but I oppose to the argument of it being simpler.

One of the major problems we often face in network engineering—and engineering more broadly—is confusing that which is simple with that which has lower complexity. Simpler things are not always less complex. Let me give you a few examples, all of which are going to be controversial.

When OSPF was first created, it was designed to be a simpler and more efficient form of IS-IS. Instead of using TLVs to encode data, OSPF used fixed-length fields. To process the contents of a TLV, you need to build a case/switch construction where each possible type a separate bit of code. You must count off the correct length for the type of data, or (worse) read a length field and count out where you are in the stream.

Fixed-length fields are just much easier to process. You build a structure matching the layout of the fixed-length fields in memory, then point this structure at the packet contents in-memory. From there, Continue reading

Cisco-F5 partnership yields secure, multisite load balancing technology

Cisco and F5 have extended their partnership with new technology that lets enterprises balance large amounts of traffic between multiple sites to ensure availability and improve application performance.Specifically, the companies are meshing Cisco’s ACI Multi-Site/Multi-Pod package with F5’s Big IP DNS software to help customers more effectively utilize resources distributed across multiple locations, according to Yousuf Khan, vice president of technical marketing with Cisco’s enterprise and datacenter networking group.ACI is built on Cisco’s intent-based networking technology, which gives customers the ability to implement network and policy changes on the fly and ensure data delivery. ACI Multi-Site typically lets two geographically dispersed data centers link via L2/L3 networks and offers consistent policy enforcement across both sites. The Multi-Pod technology lets multiple groups of equipment within the individual data centers network with each other.To read this article in full, please click here

BrandPost: How AI and ML Strengthen Networks

The explosion of interest in AI in 2023 has been primarily driven by the widespread availability of Generative AI, but Network Artificial Intelligence (AI) and Machine Learning (ML) have been at work for far longer. In this article, we're highlighting three interesting use cases to build a clearer picture of what’s happening now and where we’re going.1. AI Enhancing Network End-User ExperienceAI is being utilized to help NetOps teams manage the network end-user experience. This involves using AI and ML for efficient data collection, processing, and selection to rapidly identify and expose the most relevant information. AIOps allows network operators to correlate events across the tool stack and other data sources within your network, identify root causes and recurring issues across different environments, and assign collaboration projects for the appropriate operators and teams.To read this article in full, please click here

BrandPost: AI and the business of IT transformation

By: Trent Fierro, Blog Contributor.While digital transformation is a heavily discussed topic, the idea that IT organizations must think differently and adapt to change is rarely mentioned. There’s an expectation that the person with 10 to 15 years of experience using CLI commands will embrace the cloud, templates, and AIOps (AI for IT operations) without hesitation. That they will jump at the chance of using something new and exciting. Wrong!IT transformation involves technology advancements, people, and a new way of looking at processes and outcomes. What this means is that a network refresh usually turns into a discussion on how modern technology helps the team deliver a better user experience.
