In the past it was believed that network operators should periodically download clear text data from the Internet and put them into the configuration of their routers to make routing more secure.
RPKI is a technology to secure routing which employs proper cryptography. For years we have used it for Route Origin Authorization. New feature of routing security is being deployed now: Autonomous...
The presentation covers a prototype of my auto-bandwidth solution for Segment Routing Traffic Engineering.
The solution is open standard and multi-vendor (existing bandwidth-aware SR-TE solutions are vendor specific).
The prototype also includes an open source tool SR-TE bandwidth sampler, which collects SR policy counters via GNMI, calculates traffic rate and converts it into the BGP-LS...
In the old days of traditional separation of IP and DWDM, there was no need for IP folks to care about much other than what they used on their routers/switches (while the transport team ran the DWDM infra). These past DWDM infra approaches for maximizing the data capacity per fiber pair went for running more and more DWDM channels with grid spacings as small as possible. This meant that grid...
This talk is a short, practical story about a network engineer who wanted repeatable ECMP troubleshooting and also wanted to learn a new programming language. Starting from familiar tools (traceroute, Wireshark, RFCs), I built a small ECMP‑aware probing tool and translated manual workflows into code.
The focus is less on the tool itself and more on the method: start in a domain you trust,...
This presentation is showing and discussing observations of what trends and changes can be seen after the cable cuts near the shore of Yemen in September. We try to highlight findings and interesting changes in routing or traffic shifts.
The findings are valid globally and not just Middle East related. It serves as a great example of do's and don'ts in your routing-setup.
As the service provider market slowly consolidates, network engineers and architects will increasingly face the complex challenge of merging service provider networks. This technical talk dives into the intricacies of integrating distinct IP/MPLS network infrastructures, focusing on practical considerations and potential pitfalls. Based on past experience, we will discuss the general approach...
In high-performance optical communication systems transceiver health and efficiency are critical to network reliability and energy consumption. This presentation explores the powerful capabilities of Versatile Diagnostics Monitoring (VDM) features found in modern optical transceivers (beyond the speed of 100G) with a particular focus on the Thermoelectric Cooler (TEC) current metrics. By...
