Cisco grabs Exablaze for low-latency chip technology

Cisco will continued to build up its internal-electronics tools with its planned purchase of   field-programmable gate array (FPGA) technology designer Exablaze for an undisclosed amount.Exablaze, founded in 2013, specializes in low-latency FPGAs used to construct logically reconfigurable digital circuits for networking gear in high-performance environments such as data centers, high-frequency trading (HFT), big-data analytics, high-performance computing and  telecommunications. Exablaze products include FPGA-based switches and network interface cards (NICs), as well as picosecond-resolution timing technology.To read this article in full, please click here

Ansible Content Collections: The Sensu Go Use Case

Blog_Ansible and Sensu

In Getting Started With Ansible Content Collections, which presented the general idea behind what is becoming a new standard in the distribution of Ansible content, we learned about the what, the why and the how of Ansible Collections (and hopefully it got you excited about Ansible Collections!). In this post, we'll take things a bit further, continuing the journey into the world of Ansible Collections accompanied by the certified Sensu Go Ansible Collection that our team at XLAB Steampunk developed and supports for Sensu.

 

What to expect?

This article will guide you through the process of creating a fully functioning automated deployment of the Sensu Go monitoring agent and backend with the help of roles and modules included in the Sensu Go Ansible Collection. 

If you are not familiar with Sensu Go, this quick introduction to Sensu Go will help you get up to speed.

Before we begin, let's first talk about the collection we're taking along for the ride.

 

The Sensu Go Ansible Collection: the basics

What exactly do we need for a complete and fully functioning deployment of Sensu Go? First, the Sensu Go monitoring backend. Then, to allow the backend to Continue reading

IDG Contributor Network: SD-WAN management means more than reviewing logs and parsing events

By creating a single view of all network data, you can do things better like correlating threat information to identify real attacks or keep a log of packet statistics to better diagnose intermittent networking problems.However, to turn data into value with the limitations of traditional systems, we must be creative with the solution. We must find ways to integrate the different repositories in various appliances. It’s not an easy task but an architectural shift that I’ve written about in the past, SASE (Secure Access Service Edge), should help significantly.SASE is a new enterprise networking technology category introduced by Gartner in 2019. It represents a change in how we connect our sites, users, and cloud resources.To read this article in full, please click here

HA inside Data Center

Overview

In Leaf/Spine VXLAN based data centers, everyone likes to provide HA with Active/Active in it, so choices are different. There are two types of HA in data centers, Layer 3 and Layer 2.

For layer 3 HA, always there is more than one spine that can provide ECMP and HA at same time. However, Layer 2 redundancy for hosts and l4-l7 services that connected to leafs are more than an easy choice. As Cisco provided vPC for nearly 10 years ago, almost this was the first (and only) choice of network engineers. Also, other vendors have their own technologies. For example, Arista provided Multi-chassis Link Aggregation (MLAG) for L2 HA in leafs. But, there is always a problem in implementation of them. One example in vPC is “peer-link” that is an important component in the vPC feature. However, it can be a tough one in most cases like Dynamic Layer-3 routing over vPC or Orphan members that may cause local traffic switching between vPC peers without using Fabric links.

To address the “peer-link” issue, there is a “fabric-peering” solution that uses Fabric links instead of “peer-link” and convert it to “virtual peer-link”. With this solution there is no concern Continue reading

The Week in Internet News: U.S. Lawmakers Threaten Anti-Encryption Regulations

Don’t make us make you: Members of a U.S. Senate committee recently told representatives of Facebook and Apple that they need to give police access to customers’ encrypted communications, or they will be forced to by Congress, the Washington Post reports. The companies told lawmakers that backdoors in encryption would be exploited by cybercriminals.

Facebook declines: Meanwhile, Facebook has refused a request from U.S. Attorney General William Barr to build encryption backdoors into WhatsApp and Messenger, the New York Times reports.

Women want to be included: As Internet access is growing in the central African country of Chad, women are demanding to be in on the action, Reuters reports. Women across sub-Saharan Africa are currently 15 percent less likely to own a mobile phone than men are and 41 percent less likely to use the mobile Internet, the story says.

Gigabit tech boom: Gigabit-speed Internet service is turning some small U.S. cities into tech centers, bringing businesses and jobs to the areas, Inc. says. The story looks at businesses taking advantage of gigabit-speed networks in Chattanooga, Tennessee, Melbourne, Florida, and Sarasota, Florida.

Deep Dive Into the New Docker Desktop filesharing Implementation Using FUSE

The latest Edge release of Docker Desktop for Windows 2.1.7.0 has a completely new filesharing system using FUSE instead of Samba. The initial blog post we released presents the performance improvements of this new implementation and explains how to give feedback. Please try it out and let us know what you think. Now, we are going to go into details to give you more insight about the new architecture.

New Architecture

Instead of Samba running over a Hyper-V virtual network, the new system uses a Filesystem in Userspace (FUSE) server running over gRPC over Hypervisor sockets.

The following diagram shows the path taken by a single request from a container, for example to read a PHP file:

In step (1) the web-server in the container calls “read” which is a Linux system call handled by the kernel’s Virtual File System (VFS) layer. The VFS is modular and supports many different filesystem implementations. In our case we use Filesystem in Userspace (FUSE) which sends the request to a helper process running inside the VM labelled “FUSE client.” This process runs within the same namespace as the Docker engine. The FUSE client can handle some requests locally, but Continue reading
