Intel was the first of the major CPU makers to add HBM stacked DRAM memory to a CPU package, with the “Sapphire Rapids” Max Series Xeon 5 processors, but with the “Granite Rapids” Xeon 6, Intel abandoned the use of HBM memory in favor of what it would hope would be more main stream MCR DDR5 main memory, which has multiplexed ranks to boost bandwidth by nearly 2X over regular DDR5 memory. …

What impact do local regulations have on our ability to build and operate new data centers in the United States? What impact do these regulations have on local economies? Juan Londoño, from the Taxpayers Protection Alliance, joins Ned Bellavance and Russ White to discuss yet another part of the network engineering world.
You might have an environment where a route reflector (or a route server) has dozens or hundreds of BGP peers. Configuring them by hand is a nightmare; you should either build a decent automation platform or use dynamic BGP neighbors – a feature you can practice in the next lab exercise.

The SC24 WAN Stress Test chart shows 10.3 Terabits bits per second of WAN traffic to the The International Conference for High Performance Computing, Networking, Storage, and Analysis (SC24) conference held this week in Atlanta. The conference network used in the demonstration, SCinet, is described as the most powerful and advanced network on Earth, connecting the SC community to the world.
SC24 Real-time RoCEv2 traffic visibility describes a demonstration of wide area network bulk data transmission using RDMA over Converged Ethernet (RoCEv2) flows typically seen in AI/ML data centers. In the example, 3.2Tbits/second sustained trasmissions from sources geographically distributed around the United States was demonstrated.
SC24 Dropped packet visibility demonstration shows how the sFlow data model integrates three telemetry streams: counters, packet samples, and packet drop notifications. Each type of data is useful on its own, but together they provide the comprehensive network wide observability needed to drive automation. Real-time network visibility is particularly relevant to AI / ML data center networks where congestion and dropped packets can result in serious performance degradation and in this screen capture you can see multiple 400Gbits/s RoCEv2 flows.

Ever since AutoCon1, I've been trying to define Network Automation, at least in my own mind. The thinking is, we need to define terms before we can tackle solutions. In a jet lagged, sleep deprived moment, it occurred to me that NAF is trying to help us go from a single celled organisms to a READ MORE

Over a decade ago, I created a webinar describing enterprise MPLS/VPN use cases. Surprisingly, some networking engineers still find it useful in the wonderful new world of SD-WAN duct tape, and starting today, you can access it without an ipSpace.net account.

Distributed Denial of Service (DDoS) attacks are cyberattacks that aim to overwhelm and disrupt online services, making them inaccessible to users. By leveraging a network of distributed devices, DDoS attacks flood the target system with excessive requests, consuming its bandwidth or exhausting compute resources to the point of failure. These attacks can be highly effective against unprotected sites and relatively inexpensive for attackers to launch. Despite being one of the oldest types of attacks, DDoS attacks remain a constant threat, often targeting well-known or high traffic websites, services, or critical infrastructure. Cloudflare has mitigated over 14.5 million DDoS attacks since the start of 2024 — an average of 2,200 DDoS attacks per hour. (Our DDoS Threat Report for Q3 2024 contains additional related statistics).
If we look at the metrics associated with large attacks mitigated in the last 10 years, does the graph show a steady increase in an exponential curve that keeps getting steeper, especially over the last few years, or is it closer to linear growth? We found that the growth is not linear, but rather is exponential, with the slope dependent on the metric we are looking at.
Why is this question interesting? Simple. The answer Continue reading
When cable cuts occur, whether submarine or terrestrial, they often result in observable disruptions to Internet connectivity, knocking a network, city, or country offline. This is especially true when there is insufficient resilience or alternative paths — that is, when a cable is effectively a single point of failure. Associated observations of traffic loss resulting from these disruptions are frequently covered by Cloudflare Radar in social media and blog posts. However, two recent cable cuts that occurred in the Baltic Sea resulted in little-to-no observable impact to the affected countries, as we discuss below, in large part because of the significant redundancy and resilience of Internet infrastructure in Europe.
On Sunday, November 17 2024, the BCS East-West Interlink submarine cable connecting Sventoji, Lithuania and Katthammarsvik, Sweden was reportedly damaged around 10:00 local (Lithuania) time (08:00 UTC). A Data Center Dynamics article about the cable cut quotes the CTO of Telia Lietuva, the telecommunications provider that operates the cable, and notes “The Lithuanian cable carried about a third of the nation's Internet capacity, but capacity was carried via other routes.”
As the Cloudflare Radar graphs below show, there was no apparent impact to Continue reading
