Upcoming Events: Data Center Fabrics Workshop in Zurich

Online webinars are great, but many engineers still prefer live workshops – they’re an excellent opportunity for unrestricted 2-way communication and exchange of ideas – so I decided to turn a few of my best webinars (or webinar tracks) into workshops, and Gabi Gerber, the wonderful organizer of Data Center days in Switzerland took over the logistics, resulting in the first-ever Data Center Fabrics workshop in Zurich in late March.

Network Design – Where Should I Start?

After listening to a recent Packet Pushers podcast, the question was raised about network design and where the network design should start. When I first started designing IT, I believed the correct starting point was to define the required outcome through the deployment of technology. For example, the requirement from the customer could be to […]

Non-Blocking #1: sFlow with Peter Phaal of InMon and sFlow.org

The inaugural "Non-Blocking" podcast for ForwardingPlane.net. We discuss sFlow with one if its creators, Peter Phaal of InMon.Discuss sFlow, the protocol, it's uses, similarities to other management frameworks, how it is dissimilar from netflow and why it is worth while to take some time to learn it.

Break Those Chains

So because I’m new to this whole blogging at Packet Pushers thing (and blogging in general), I’ve been trying to decide on my place in the grand scheme of things. There are a lot of folks here that do a great job of deep-dives, vendor happenings, and general overviews. I could do those, but what’s the point of rehashing what this site and 100s of others (Google FTW) do?

Demystifying NFV Infrastructure Hotspots

Slides from the recent Dell NFV Summit 2015 are now available. Steve Wright's 7 Fallacies of NFV talk describes the importance of managing network resources in an NFV stack. The diagram above shows the complex network data paths that result from NFV as packets flow between virtual functions across physical and virtual switches.
The presentation describes how the Fallacies of Distributes Computing apply to NFV, highlighting the importance of effective management of network resources for effective NFV deployment.

Another paper, Demystifying NFV Infrastructure Hotspots by Ramki Krishnan, Anoop Ghanwani, and Michael Tien, demonstrates how industry standard sFlow instrumentation build into physical and virtual switches can provide the comprehensive real-time analytics needed to manage NFV deployments.
The vIMS (virtualized IP Multimedia Subsystem) is used as an example. The diagram below shows the functional elements of the logical architecture deployed on the hardware testbed shown above.
sFlow telemetry from the physical switches in the leaf and spine network, virtual switch instances, and hypervisors is streamed to an instance of the sFlow-RT analytics platform.
The dashboard application running on sFlow-RT demonstrates visibility into the traffic flows between virtual network functions.
The final set of charts in the dashboard shows the multi-media traffic flows running Continue reading

Worth Reading: Internet Governance 2015

In 2015 we saw many agreements on Internet Governance. 193 Governments agreed in the UN General Assembly on the WSIS 10+ Outcome Document. They agreed to extend the mandate of the IGF for ten years. They agreed to strengthen the multistakeholder approach. And they agreed to make more efforts to bring the next billion users online until 2020. -via circle id

Pakistan unblocks YouTube after Google launches local version

Pakistan has lifted a ban on YouTube in the country after Google offered a localized version, which the government claims will allow it to ask for the removal of material considered offensive from the website.YouTube was ordered blocked in Pakistan in 2012 after a controversial video, called the "Innocence of Muslims," created a controversy in many countries for mocking the Prophet Muhammad.Pakistan authorities told a court that they were blocking the whole domain because it was not technically feasible for them to block specific links to the video.To read this article in full or to leave a comment, please click here

It’s an exciting time in networking!

web-IT

Google and Amazon recently gave the IT community a glimpse behind the curtain of web-IT, revealing the outcome of their pioneering efforts. It’s no surprise that they’ve settled on IP fabrics and network virtualization to provide both scale and isolation. Web giants Facebook and Microsoft are both driving open hardware in an effort to eliminate the lock that industry incumbents have on networking solutions.

You know that you’re onto something when industry analysts start counting things – Gartner’s Andrew Lerner recently published his perspective on the networking industry; by 2017, they expect 50% of global enterprises to embrace web-IT architectures.

Last year, we saw the uptake of modern networking paradigms. Practitioners of NetDevOps are driving automation practices into the network domain. IP storage solutions are rampant, benefiting from high capacity IP fabrics. Brite-box hardware suppliers have enabled web-IT with procurement, logistics, and support capability that meets the needs of any organization. Network virtualization solutions from VMware NSX and up-and-comer Nuage are getting the nod in enterprises. The OpenStack community applied a laser-like focus on Neutron which in turn has promoted virtual network solutions from Akanda and Midokura to be deployed at scale. We’re seeing Continue reading
