Mode and Versa Use Ericsson’s Global Network for SD-WAN

The two vendors are offering connectivity and SD-WAN over Ericsson’s private network. The offering looks similar to Aryaka’s.

The QUICening

Six o’clock already, I was just in the middle of a dream, now I’m up, awake, looking at my Twitter stream. As I do that the Twitter app is making multiple API calls over HTTPS to Twitter’s servers somewhere on the Internet.

Those HTTPS connections are running over TCP via my home WiFi and broadband connection. All’s well inside the house, the WiFi connection is interference free thanks to my eero system, the broadband connection is stable and so there’s no packet loss, and my broadband provider’s connection to Twitter’s servers is also loss free.

Those are the perfect conditions for HTTPS running over TCP. Not a packet dropped, not a bit of jitter, no congestion. It’s even the perfect conditions for HTTP/2 where multiple streams of requests and responses are being sent from my phone to websites and APIs as I boot my morning. Unlike HTTP/1.1, HTTP/2 is able to use a single TCP connection for multiple, simultaneously in flight requests. That has a significant speed advantage over the old way (one request after another per TCP connection) when conditions are good.

But I have to catch an early train, got to be to work by nine, so Continue reading

Monitoring and Visibility for the Hybrid Cloud

Upcoming Webinars and Events: October 2018

The fast pace of webinars continues in October 2018:

• Rachel Traylor will talk about graph theory and its relevance to reliable network design on October 8^th;
• The Amazon Web Services Networking webinar will start on October 11^th. The second session is planned for October 25^th;
• On October 16^th we’ll have the third session of VMware NSX technical deep dive (unless I manage to finish on time later today… not likely).

There are no on-site events planned until early December:

• We’ll run another on-site workshop in Zurich on December 5^th . This time we’ll focus on using VXLAN and EVPN to build multi-site fabrics;
• I’ll talk about making SDN better with IPv6 on December 6^th.

You can attend all upcoming webinars with an ipSpace.net webinar subscription. Online courses and on-site events require separate registration.

AWS ABCs — EC2 Internet Connectivity

So, you've created a compute instance (ie, a virtual machine) on Amazon EC2. Next question: does the instance require access to and/or from the Internet?

Protip: just because you created the instance in the public cloud, i.e. the cloud that you get to over the Internet, it doesn't mean that your instances all need to sit on the Internet. They can have direct inbound and outbound Internet access, no Internet access, or something in between (which I'll explain).

The basic building block for networking on AWS is the VPC (Virtual Private Cloud). Within a VPC, you define your IP space, gateways, ACLs, DHCP options, and more. Gateways will be the focus of this article.

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

Digital Realty already has data centers in North America, Europe, Asia, and Australia. This expands its data center footprint to Latin American — a region primed for growth.

The Future Is Dispensable Servers

For a server to be truly dispensable, it should be able to be shut down at will or fail without any noticeable end-user impact.

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

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
