Cisco Virtual Router for Cloud Services : Cisco CSR1000v
What is the purpose of Cisco CSR 1000v routers ?
With all the intent-based hype (and the previous SDN-will-rule-the-world-hype) you’d think that the network is the ultimate ossified roadblock on the path to agile nirvana.
You’d be totally wrong (and you’d deserve it – never trust a vendor peddling a product).
Here’s an amazing discovery I made when I was still running on-site SDN and network automation workshops.

Someone was having trouble figuring out why the ios_config module didn’t apply his template correctly. I explained what was wrong with the template, afterwards I thought about the issue some more and realized that the error could potentially be really dangerous. As in a game-over-level-event for your employment dangerous. Continue reading
This past weekend, North Korea expert Martyn Williams and I spotted the activation of a new internet path out of North Korea. At 09:07:51 UTC on 1 October 2017, the country’s single internet provider, Star JV (AS131269), gained a new connection to the global internet through Russian fixed-provider Transtelecom (AS20485), often referred to as TTK. Martyn published his analysis on the US-Korea Institute‘s 38 North blog, named after the dividing line between North and South Korea.
The internet of North Korea is very small (four BGP routes) and reportedly only accessible by a few elites in the country. Since the appearance of AS131279 in the global routing table almost 7 years ago, Star JV has almost exclusively relied on China Unicom for its connectivity to the global internet — the only exception was its partial usage of satellite service from Intelsat between 2012 and 2013. In light of this history, a new internet connection out of North Korea is certainly a notable development.
Unsteady Connection
At 09:07:51 UTC, TTK (AS20485) appeared as a transit provider for three of the four BGP routes announced by AS131279, namely, 175.45.176.0/24, 175.45.178.0/24, and Continue reading
Chip giant Intel has been talking about CPU-FPGA compute complexes for so long that it is hard to remember sometimes that its hybrid Xeon-Arria compute unit, which puts a Xeon server chip and a midrange FPGA into a single Xeon processor socket, is not shipping as a volume product. But Intel is working to get it into the field and has given The Next Platform an update on the current plan.
The hybrid CPU-FPGA devices, which are akin to AMD’s Accelerated Computing Units, or APUs, in that they put compute and, in this case, GPU acceleration into a single …

The DockerCon Hallway Track is coming to DockerCon Europe in Copenhagen. We’ve partnered with e180.co once again to deliver the next level of conference attendee networking. Together, we believe that education is a relationship, not an institution, and that a conversation can change someone’s life. After the success of our collaboration in Austin with Moby Mingle, we’re happy to be growing this idea further for Copenhagen.
DockerCon is all about learning new things and connecting with the right people. The Hallway Track will help you meet and share knowledge with community members and practitioners at the conference.
So, what’s a Hallway Track?
DockerCon Hallway Track is a one-on-one or group conversations based on topics of interest that you schedule with other attendees during DockerCon. Hallway Track’s recommendation algorithm curates an individualized selection of Hallway Track topics for each participant, based on their behavior and interests.

Ripple’s XRP Ledger is a blockchain-based payment network that transfers funds between any type of currency within a few seconds with average transaction costs of a fraction of a penny. The core of this peer-to-peer network is an open source C++ application called rippled. Ripple’s goal is to supplant the world’s existing legacy payment networks. As such, scalability is a continuous goal. This document describes how the rippled team has integrated performance engineering into its development processes, and how this has contributed to throughput gains of over 1000%.
Performance engineering practices deliver benefits in addition to measurable performance gains. These include the ability to report on the capabilities of the software so that users can feel confident that their needs will be met by the system. Performance engineering informs capacity planning and optimal configuration of environments to support the application. Many performance problems are caught and addressed before customers notice them. As process automation improves, each change to the software can be quickly assessed for improvement or regression. This methodology also makes better use of developer time by helping choose the most effective tasks for improving performance. Any software project serious about supporting global scale should integrate performance engineering Continue reading
