BGP Updates cin 2025

The first part of this annual report on BGP for the year 2024 looked at the size of the routing table and some projections of table growth for both IPv4 and IPv6. However, the scalability of BGP as the Internet’s routing protocol is not just dependant on the number of prefixes carried in the routing table. BGP protocol behaviour in the form of dynamic routing updates are also part of this story. This second part of this report looks at the profile of BGP updates across 2023 to assess whether the stability of the routing system, as measured by the level of BGP update activity, is changing.

I just passed the AWS Advanced Networking Specialty

It’s been almost exactly 11 years since I passed the R&S CCIE lab in Brussels, and now it was time to go with something more cloudy 🙂 I just passed the AWS Advanced Networking Specialty, and unlike CCIE I did this one on my first attempt. I did stay pretty much in networking during the last years, but shifted to significantly less Cisco and quite much into cloud architecture – mostly AWS. Since networking is the heart of every cloud architecture, and after 4 years of hands-on work with complex AWS networking projects, I decided it was time to validate

The post I just passed the AWS Advanced Networking Specialty appeared first on How Does Internet Work.

Human Cognition Can’t Keep Up With Modern Networks. What’s Next?

Sanil Nambiar, client engagement lead, AI for networks, at IBM: Assembling the infrastructure organizations will need for AI. “The strategy, obviously, is hybrid cloud, data and AI and automation working together as an architecture,” Nambiar told me in this episode of The New Stack Makers. IBM has invested in what he calls “three foundational platforms” because each offers capabilities essential to AI infrastructure. Red Hat, a hybrid cloud platform, is needed “for that consistent runtime across on-prem and cloud,” he said. HashiCorp offers “life cycle control and policy-driven automation.” And Confluent is for “real-time, contextual, trustworthy data access for AI.” All of these platforms are needed, Nambiar said, because  “AI does not sit on top of chaos and magically fix it. You really need environments which are consistent, infrastructure that is programmable, data that moves in real time.” The Core Challenges of Modern Network Operations The new complexity AI introduces has added to the challenges networking Continue reading

Sidecarless mTLS in Kubernetes: How Istio Ambient Mesh and ztunnel Enable Zero Trust

Encrypting internal traffic and enforcing mutual (mTLS), a form of TLS in which both the client and server authenticate each other using X.509 certificates., has transitioned from a “nice-to-have” to a hard requirement, especially in Kubernetes environments where everything can talk to everything else by default. Whether your objectives are regulatory compliance, or simply aligning to the principles of Zero Trust, the goal is the same: to ensure every connection is encrypted, authenticated, and authorized.

Delivering Cluster-Wide mTLS Without Sidecars

The word ‘service mesh’ is bandied about as the ideal solution for implementing zero-trust security but it comes at a price often too high for organizations to accept. In addition to a steep learning curve, deploying a service mesh with a sidecar proxy in every pod scales poorly, driving up CPU and memory consumption and creating ongoing maintenance challenges for cluster operators.

Istio Ambient Mode addresses these pain points by decoupling the mesh from the application and splitting the service mesh into two distinct layers: mTLS and L7 traffic management, neither of which needs to run as a sidecar on a pod. By separating these domains, Istio allows platform engineers to implement mTLS cluster-wide without the complexity of Continue reading

UET Congestion Management: CCC Base RTT

Calculating Base RTT

[Edit: January 7 2026, RTT role in CWND adjustment process]

As described in the previous section, the Bandwidth-Delay Product (BDP) is a baseline value used when setting the maximum size (MaxWnd) of the Congestion Window (CWND). The BDP is calculated by multiplying the lowest link speed among the source and destination nodes by the Base Round-Trip Time (Base_RTT).

In addition to its role in BDP calculation, Base_RTT plays a key role in the CWND adjustment process. During operation, the RTT measured for each packet is compared against the Base_RTT. If the measured RTT is significantly higher than the Base_RTT, the CWND is reduced. If the RTT is close to or lower than the Base_RTT, the CWND is allowed to increase.

This adjustment process is described in more detail in the upcoming sections.

The config_base_rtt parameter represents the RTT of the longest path between sender and receiver when no other packets are in flight. In other words, it reflects the minimum RTT under uncongested conditions. Figure 6-7 illustrates the individual delay components that together form the RTT.

A closer look at a BGP anomaly in Venezuela

As news unfolds surrounding the U.S. capture and arrest of Venezuelan leader Nicolás Maduro, a cybersecurity newsletter examined Cloudflare Radar data and took note of a routing leak in Venezuela on January 2.

We dug into the data. Since the beginning of December there have been eleven route leak events, impacting multiple prefixes, where AS8048 is the leaker. Although it is impossible to determine definitively what happened on the day of the event, this pattern of route leaks suggests that the CANTV (AS8048) network, a popular Internet Service Provider (ISP) in Venezuela, has insufficient routing export and import policies. In other words, the BGP anomalies observed by the researcher could be tied to poor technical practices by the ISP rather than malfeasance.

In this post, we’ll briefly discuss Border Gateway Protocol (BGP) and BGP route leaks, and then dig into the anomaly observed and what may have happened to cause it. 

Background: BGP route leaks

First, let’s revisit what a BGP route leak is. BGP route leaks cause behavior similar to taking the wrong exit off of a highway. While you may still make it to your destination, the path may be slower and come with delays you Continue reading

BGP in 2025

At the start of each year, it’s been my practice to report on the behaviour of the Internet’s inter-domain routing system over the previous 12 months, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet.

Using eBPF to load-balance traffic across UDP sockets with Go

Akvorado collects sFlow and IPFIX flows over UDP. Because UDP does not retransmit lost packets, it needs to process them quickly. Akvorado runs several workers listening to the same port. The kernel should load-balance received packets fairly between these workers. However, this does not work as expected. A couple of workers exhibit high packet loss:

$ curl -s 127.0.0.1:8080/api/v0/inlet/metrics \
> | sed -n s/akvorado_inlet_flow_input_udp_in_dropped//p
packets_total{listener="0.0.0.0:2055",worker="0"} 0
packets_total{listener="0.0.0.0:2055",worker="1"} 0
packets_total{listener="0.0.0.0:2055",worker="2"} 0
packets_total{listener="0.0.0.0:2055",worker="3"} 1.614933572278264e+15
packets_total{listener="0.0.0.0:2055",worker="4"} 0
packets_total{listener="0.0.0.0:2055",worker="5"} 0
packets_total{listener="0.0.0.0:2055",worker="6"} 9.59964121598348e+14
packets_total{listener="0.0.0.0:2055",worker="7"} 0

eBPF can help by implementing an alternate balancing algorithm. 🐝

Options for load-balancing

There are three methods to load-balance UDP packets across workers:

  1. One worker receives the packets and dispatches them to the other workers.
  2. All workers share the same socket.
  3. Each worker has its own socket, listening to the same port, with the SO_REUSEPORT socket option.

SO_REUSEPORT option

UET Congestion Management: Congestion Control Context

Congestion Control Context

Updated 5.1.2026: Added CWND computation example into figure. Added CWND cmputaiton into text.
Updated 13.1.2026: Deprectade by: Ultra Ethernet: Congestion Control Context 

Ultra Ethernet Transport (UET) uses a vendor-neutral, sender-specific congestion window–based congestion control mechanism together with flow-based, adjustable entropy-value (EV) load balancing to manage incast, outcast, local, link, and network congestion events. Congestion control in UET is implemented through coordinated sender-side and receiver-side functions to enforce end-to-end congestion control behavior.

On the sender side, UET relies on the Network-Signaled Congestion Control (NSCC) algorithm. Its main purpose is to regulate how quickly packets are transmitted by a Packet Delivery Context (PDC). The sender adapts its transmission window based on round-trip time (RTT) measurements and Explicit Congestion Notification (ECN) Congestion Experienced (CE) feedback conveyed through acknowledgments from the receiver.

On the receiver side, Receiver Credit-based Congestion Control (RCCC) limits incast pressure by issuing credits to senders. These credits define how much data a sender is permitted to transmit toward the receiver. The receiver also observes ECN-CE markings in incoming packets to detect path congestion. When congestion is detected, the receiver can instruct the sender to change the entropy value, allowing traffic to be Continue reading
