AI agents change network traffic patterns completely. Instead of humans opening browsers and apps, autonomous systems start talking directly to APIs, databases, sensors, and other agents. IPv6 removes the address limitations and NAT complexity that break large-scale AI communication.
Large VLAN domains depend on spanning tree. Every topology change triggers recalculation and temporary forwarding loss. EVPN-VXLAN replaces large Layer 2 domains with routed underlays and distributed MAC learning. Regional ISPs use this to connect data centers, IX edge infrastructure, and broadband aggregation networks without stretching spanning tree across sites VXLAN encapsulates Ethernet frames inside … Read more
From Cambium This email is to inform you that within the next ~24 hours, Cambium expects to release a new 25.0.1 as a replacement for 25.0. Cambium became aware of a longstanding issue for potential javascript execution on log pages. 25.0 was also discovered to have a bug with Technician level user access being allowed … Read more
Effective network engineering is intentionally unobtrusive. When systems remain stable, support tickets are not generated. If routing functions correctly, inquiries are absent. When redundancy operates as intended, disruptions are imperceptible.
Whether you’re a seasoned engineer or just getting started, this post will walk you through the six most common MikroTik configuration errors and how to avoid them.
ISP engineers have traditionally been a “person of many hats”. There are many things that keep us up at night. Among them are some of the following.
When you run a network, you’ll hit this situation sooner or later. A customer buys a service, but the issue they are dealing with is not related to your network. It is theirs. But do you help them?
Many engineers use the term VLAN in a broad way, often referring to any logical separation on a switch. However, a standard VLAN and a Private VLAN address different needs. Mixing them up can lead to network design mistakes.
The three-tier model of core (edge), distribution, and access remains the foundation of ISP network architecture, though the distinctions between these layers have become less defined. A current assessment requires analysis beyond standard diagrams.
Many Internet service providers believe PeeringDB is just for networks in large data centers. That belief sticks around like an old patch cable at the bottom of a toolbox. The reality is simpler: every ISP should have a PeeringDB entry, even if you never set foot in a carrier hotel, IXP, or meet-me room. Your … Read more
When BEAD winners build new last-mile or middle-mile networks, connecting back to the global Internet is essential. Without a nearby exchange, that traffic may have to travel hundreds of miles to a major metro before reaching popular destinations like cloud providers, streaming platforms, or even local government websites. This detour adds latency, reduces performance, and increases costs.
