Reference Guide Update: Deploying NSX Data Center on an ACI Underlay

NSX Data Center is now the de facto SDN standard for the Private Cloud. Reference guides for NSX Data Center are proven to reduce complexity in managing the physical switch infrastructure. This increases the infrastructures stability and requires a minimal set of system and service configuration to bring up the fabric. Organizations utilize NSX Data Center for a diverse set of use cases including security, a diverse application framework deployment platform, and application continuity across private and hybrid clouds.  With reference designs for any underlay, NSX Data Center is fulfilling its promise to be a platform over any infrastructure. NSX Data Center provides the cornerstone for the Virtual Cloud Network.

Overview of NSX Data Center with ACI Underlay

Ever since publishing our original design guide Deploying NSX with Cisco ACI as an Underlay, there has been an avalanche of interest in building out a more simplified Cisco infrastructure with ACI as the underlay. Most of the requests are for more detail when constructing the ACI underlay. The high-level design guidance in the original NSX reference design for ACI discussed the minimum ACI constructs necessary for an NSX Data Center deployment. These ideals have not changed.  The original paper called Continue reading

Digital Realty Buys Ascenty for $1.8B, Battles Equinix for Cloud, Interconnection Deals

Will Operators Use Alternative Backhaul Technologies to Deliver on 5G?

WiFi, fixed access, and satellites are promising technologies that operators should consider as viable alternatives to fiber or microwave for 5G backhaul.

Intel makes a play for high-speed fiber networking for data centers

Intel is revamping its strategy around the data center by going beyond the Xeon chip and into silicon photonics transceivers. The company announced Monday at the European Conference on Optical Communications (ECOC) that samples of its silicon photonics transceivers targeting 5G wireless infrastructure and data centers are available now, with production set to start in the first quarter of 2019.The company notes that global data center IP traffic is increasing significantly. In 2016, global data center IP traffic was 6.8 zettabytes, and that will triple by 2021 because of all this data generated by humans and the Internet of Things (IoT).The choke point becomes copper wire, the standard for Ethernet connectivity. Copper wire can only effectively transmit about eight to 10 meters, said Eoin McConnell, director of marketing for the connectivity group in Intel’s data center group. Fiber optics can go as far as 10 kilometers.To read this article in full, please click here

Microsoft Azure IoT Plans Now Support Digital Twins

The integration allows users to manage the digital model using event-driven and serverless methods that can then be transferred to the physical environment.

Worth Reading: eVPN Behind the Curtain

Is EVPN magic? Well, like Arthur C Clarke said, any considerable leap in technology is indistinguishable from magic. On that premise, moving from a traditional layer 2 environment to VXLAN driven by EVPN has much of that same hocus pocus feeling. —Rama Darbha and Eric Pulvino @Cumulus

BGP Security: A Gentle Reminder that Networking is Business

At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security—specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for… 20 years? … at this point, so I have seen the argument develop across these years many times, and in many ways. What always strikes me about this discussion, whenever and wherever it is aired, is the clash between business realities and the desire for “someone to do something about routing security in the DFZ, already!” What also strikes me about these conversations it the number of times very fundamental concepts end up being explained to folks who are “new to the problem.”

Part of the problem here is Continue reading

IGF 2018: Improvements and a Call for Contributions

The annual meetings of the Internet Governance Forum (IGF) have been consolidated as the main space for discussion and exchange of ideas among the stakeholders of the Internet community on an equal footing. However, there are diverse activities which take place throughout the year that require the participation of all the actors of the community.

The Intersessional Activities

The concept of Dynamic Coalitions (DCs) emerged during the first IGF meeting in 2006. These are informal groups, focused on specific topics that report their activities to the IGF Secretariat each year. Currently, there are 17 active coalitions, which involve diverse topics ranging from accessibility and disability to Internet core values. It is possible to join the work of each of them by accessing the site published by the IGF Secretariat.

On the other hand, following the recommendations of the Working Group on IGF Improvements, the IGF community promoted the creation of the Best Practice Forums (BPFs) as a way to generate more tangible outcomes. For the 2018 cycle, four BPFs were approved; all of them are currently seeking feedback from the community. Some of them have a deadline of September 30, while others will receive contributions until October 15. Continue reading

Worth Reading: Internet Reliability Report

Internet connectivity at the inter-domain level is based on connectivity between Autonomous Systems (ASes). As the number of alternate routes between ASes increases, so does fault-resistance and the stability of the Internet in a given economy increase. However, some paths prove to be more important than others. —Alexander Azimov @APNIC
