Cisco Twists Open Its Intent Networking
The rise of public clouds, the Internet of Things, greater mobility, and the more devices connecting to corporate networks is creating highly distributed environments for enterprises where applications can come from a variety of places, workloads can run on-premises or somewhere in multiple public clouds and computing resources can be located anywhere from the datacenter through branch offices and the network edge and out in the cloud. …

Weekend Reads 061518: A 51% attack materializes
We have also discovered a new stage 3 module that injects malicious content into web traffic as it passes through a network device. At the time of our initial posting, we did not have all of the information regarding the suspected stage 3 modules. The new module allows the actor to deliver exploits to endpoints via a man-in-the-middle capability (e.g. they can intercept network traffic and inject malicious code into it without the user’s knowledge). With this new finding, we can confirm that the threat goes beyond what the actor could do on the network device itself, and extends the threat into the networks that a compromised network Continue reading

Show 394: Technology Problems Are Mostly People Problems
You are a problem…maybe the biggest problem of all. No? The crashing router code is the biggest problem? The leaking memory in the switch?
The app needs layer 2 stretched between data centers–what problem could be worse than that?
Today on the show, we re here to argue that, no…it s you. And me. And everyone else you work with.
With us today to defend the idea that technology problems are really people problems is Eyvonne Sharp, network architect and co-founder of The Network Collective.
We talk about how people and processes can contribute more to a problem than a technology. We also talk about three different organizational culture types (Pathological, Bureaucratic, and Generative), how to evaluate your own organization, and Eyvonne recommends a few books on team building and culture development.

EuroDIG 2018 Gathers the Internet Community: What’s New
The 12th edition of the European Dialogue on Internet Governance or the EuroDIG, as it is commonly known, took place in Tbilisi, Georgia, on 5-6 June. The Internet Society (ISOC) is an institutional partner to EuroDIG and the ISOC European Regional Bureau helped shape the agenda and were involved in several sessions.
This year, a few specific aspects caught my attention and created a lot of debate during the sessions and in the corridors.
Reinforcing the multistakeholder model
While European governments have traditionally been strong supporters of the Internet Governance Fora (IGF) and the multistakeholder model, this support has been to some extent compromised by concerns over national security and other priorities in the recent times. Several core members of the European Internet community have talked about a “fatigue” with the regional and national IGFs.
This year’s EuroDIG offered some fresh food for thought. Larry Strickling, who leads the Internet Society’s Collaborative Governance project, made several interventions during the EuroDIG. Strickling’s extensive experience of driving multistakeholder processes and his practical approach were received with great interest and curiosity. In parallel, high participation from young people injected heaps of new energy and optimism to the event.

5 Myths About Hyperconvergence Software
Myths about the drawbacks and limits of hyperconvergence software have spread due to the fact that many of these “appliance solutions in software clothing” don’t have the flexibility of a true software solution.
Hackathon@AIS: Summary report
The annual Hackathon@AIS, in its second year, is aimed at exposing engineers from the Africa region to open Internet Standards Development. This year, the event was held 9-10 May 2018 in Dakar Senegal at the Radisson Blu Hotel during the Africa Internet Summit (AIS-2018).
The event was attended by more than 75 engineers from 15 countries including 11 fellows who were supported to attend the event. The event featured participants with English and or French-speaking backgrounds encouraging collaboration to work. Organized into 3 tracks, the event allowed participants to choose which track they were interested in participating in. The tracks were as follows:
1. Network Time Protocol Track
Objectives:
- Make NTP more secure (Privacy)
- Using WireShark NTP Plugin to read/analyze NTP traffic
- Code changes to NTP implementations to make them compliant with the draft
- Read and understand Draft RFC
Facilitators:
- Loganaden Velvindron (Mauritius)
- Nitin Mutkawoa (Mauritius)
- Serge-Parfait Goma (Congo)
Participants were introduced to NTP and asked to test out an IETF draft and implement it in open source NTP clients.
Outcome:
Participants were able to successfully implement draft and made presentations demonstrating their work and accomplishments.
2. Network Programmability
Objectives:
- Introduce participants to Software Defined Networking (SDN)
- Introduce network Continue reading

Worth Reading: Discovering Issues with HTTP/2
A while ago I found an interesting analysis of HTTP/2 behavior under adverse network conditions. Not surprisingly:
When there is packet loss on the network, congestion controls at the TCP layer will throttle the HTTP/2 streams that are multiplexed within fewer TCP connections. Additionally, because of TCP retry logic, packet loss affecting a single TCP connection will simultaneously impact several HTTP/2 streams while retries occur. In other words, head-of-line blocking has effectively moved from layer 7 of the network stack down to layer 4.
What exactly did anyone expect? We discovered the same problems running TCP/IP over SSH a long while ago, but then too many people insist on ignoring history and learning from their own experience.
Popular is cheaper: curtailing memory costs in interactive analytics engines
Popular is cheaper: curtailing memory costs in interactive analytics engines Ghosh et al., EuroSys’18
(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).
We’re sticking with the optimisation of data analytics today, but at the other end of the spectrum to the work on smart arrays that we looked at yesterday. Getafix (extra points for the Asterix-inspired name, especially as it works with Yahoo!’s Druid cluster) is aimed at reducing the memory costs for large-scale in-memory data analytics, without degrading performance of course. It does this through an intelligent placement strategy that decides on replication level and data placement for data segments based on the changing popularity of those segments over time. Experiments with workloads from Yahoo!’s production Druid cluster that Getafix can reduce memory footprint by 1.45-2.15x while maintaining comparable average and tail latencies. If you translate that into a public cloud setting, and assuming a 100TB hot dataset size — a conservative estimate in the Yahoo! case — we’re looking at savings on the order of $10M per year.
Real-time analytics is projected to Continue reading

DockerCon Guest Speaker: Liberty Mutual
In yesterday’s DockerCon keynote, Eric Drobisewski, Senior Architect at Liberty Mutual Insurance, shared how Docker Enterprise Edition has been a foundational technology for their digital transformation.
If you missed it, the replay of the keynote is available below:
Turning Disruption into Opportunities
Liberty Mutual – the 3rd largest property and casualty insurance provider in the United States – recognizes that the new digital economy is bringing a faster cycle of technology evolution. Disruptive technologies like autonomous vehicles and smart homes are changing the way customers interact and transact. Liberty Mutual sees these as opportunities to bring new services to market and ways to reinvent traditional insurance models, but they needed to become more flexible and agile while managing their technical debt.
Rapid Expansion of Docker EE
As a 106-year old company, Liberty Mutual recognized that they were not going to become agile overnight. Liberty Mutual has instead built a “multi-lane highway” that enables both traditional apps and new microservices apps to modernize at different speeds according to their needs, all based on Docker Enterprise Edition.
“(Docker Enterprise Edition) began to open multiple paths for our teams to modernize traditional applications and move them to the cloud in a Continue reading
