Google launches VMs powered by newest Intel Xeon

Google Cloud announced new virtual machines as part of its cloud platform based on Intel’s newest Xeon Scalable processors.In addition to the new C3 virtual machine series, Google also announced it is deploying Infrastructure Processing Units (IPU), which are designed to intelligently route network traffic and take the load of network data processing off the CPU. The  company made the announcements at its Google Cloud Next ’22 conference held virtually.The IPU chip, formally known as the E2000, was co-designed by Google and Intel together and features 16 Arm Neoverse cores and 200GbE networking.C3 machine instances deliver performance gains of up to 20% over previous generation of C2 instances. They also benefit from a recent product launch called Hyperdisk, a block storage system that offers 80% higher IOPS per vCPU for data analytics and DBMS workloads when compared to other hyperscalers,To read this article in full, please click here

Cloudflare DDoS threat report 2022 Q3

This post is also available in Français, Español, Português, 한국어, 简体中文, 繁體中文, and 日本語.

Welcome to our DDoS Threat Report for the third quarter of 2022. This report includes insights and trends about the DDoS threat landscape - as observed across Cloudflare’s global network.

Multi-terabit strong DDoS attacks have become increasingly frequent. In Q3, Cloudflare automatically detected and mitigated multiple attacks that exceeded 1 Tbps. The largest attack was a 2.5 Tbps DDoS attack launched by a Mirai botnet variant, aimed at the Minecraft server, Wynncraft. This is the largest attack we’ve ever seen from the bitrate perspective.

It was a multi-vector attack consisting of UDP and TCP floods. However, Wynncraft, a massively multiplayer online role-playing game Minecraft server where hundreds and thousands of users can play on the same server, didn’t even notice the attack, since Cloudflare filtered it out for them.

General DDoS attack trends

Overall this quarter, we've seen:

• An increase in DDoS attacks compared to last year.
• Longer-lasting volumetric attacks, a spike in attacks generated by the Mirai botnet and its variants.
• Surges in attacks targeting Continue reading

OSPF External Routes (Type-5 LSA) Mysteries

Daniel Dib posted a number of excellent questions on Twitter, including:

While forwarding a received Type-5 LSA to other areas, why does the ABR not change the Advertising Router ID to it’s own IP address? If ABR were able to change the Advertising Router ID in the Type-5 LSA, then there would be no need for Type-4 LSA which meant less OSPF overhead on the network.

TL&DR: The current implementation of external routes in OSPF minimizes topology database size (memory utilization)

Before going to the details, try to imagine the environment in which OSPF was designed, and the problems it was solving.

What is a network router?

By most definitions, the network router’s purpose is defined by its name – it routes packets from one location to another. But over the course of decades of internet networking, the value of the router has grown significantly, offering enterprises additional functions such as network security, content filtering, quality of service, and more.At its most basic level, a router is a device that connects networks to each other, forwarding data packets from one location to another until they reaches their destination. Within a local area network (LAN), a router can also allow multiple devices to use the same Internet connection, such as how a home router allows users to connect their laptops, phones and tablets (among countless other devices) at the same time.To read this article in full, please click here

Using functions in bash to selectively run a group of Linux commands

Using a function in bash allows you to create something in Linux that works as if it were a script within a script. Whenever the data being processed matches a set of conditions, your script can call a function that does further processing.The format of a function is very straightforward. The syntax looks like this:<function_name> () { <commands> } You can also use the following format that uses the word "function" if you prefer:function <function_name> { <commands> } In fact, you can also create a function on a single line if the commands to be run are limited, but note the required “;” that follows the command(s):To read this article in full, please click here
