Heavy Networking 475: Anticipating 5G’s Impact On Enterprise Wi-Fi

On today's Heavy Networking podcast, Greg and Ethan engage in a thought experiment: Will 5G and private LTE allow enterprises to get rid of their own wireless networks and shift much of that responsibility on telcos and just let them do it? They explore this idea from the telco and enterprise perspectives.

Understanding BGP Labeled Unicast

We’ve talked in previous posts on how we can use LDP and RSVP as label distribution protocols. Without LDP and RSVP – we wouldn’t be able to easily create LSPs which means we’d have to do it manually as we did in my first post on MPLS. That being said – the discussion around MPLS label distribution usually focuses around these two protocols, but you might (or might not depending on how long you’ve been in networking) be surprised to learn that we can also use BGP to advertise labels. That is – we can build end to end LSPs without the use of LDP or RSVP. Using BGP for label distribution comes with it’s own set of requirements (and associated oddities) so in this post we’ll talk through the use case.

Advertising labels through BGP is something that we’ve seen before. Specifically, we saw it in the MPLS VPN use case where PE routers advertise a VPN label so that the remote PE knows what VRF/VPN the traffic belongs in. In that use case, we did a BGP peering with the inet-vpn address family. To do BGP labeled unicast (commonly called BGP-LU) we do a BGP peering with the Continue reading

Redundant BGP Connectivity on a Single ISP Connection

A while ago Johannes Weber tweeted about an interesting challenge:

We want to advertise our AS and PI space over a single ISP connection. How would a setup look like with 2 Cisco routers, using them for hardware redundancy? Is this possible with only 1 neighboring to the ISP?

Hmm, so you have one cable and two router ports that you want to connect to that cable. There’s something wrong with this picture ;)

IDG Contributor Network: Secure Access Service Edge (SASE): A reflection of our times

There’s a buzz in the industry about a new type of product that promises to change the way we secure and network our organizations. It is called the Secure Access Service Edge (SASE). It was first mentioned by Gartner, Inc. in its hype cycle for networking. Since then Barracuda highlighted SASE in a recent PR update and Zscaler also discussed it in their earnings call. Most recently, Cato Networks announced that it was mentioned by Gartner as a “sample vendor” in the hype cycle.To read this article in full, please click here

DARPA looks for new NICs to speed up networks

The government agency that gave us the Internet 50 years ago is now looking to drastically increase network speed to address bottlenecks and chokepoints for compute-intensive applications.The Defense Advanced Research Projects Agency (DARPA), an arm of the Pentagon, has unveiled a computing initiative, one of many, that will attempt to overhaul the network stack and interfaces that cannot keep up with high-end processors and are often the choke point for data-driven applications.[Get regularly scheduled insights by signing up for Network World newsletters. ] The DARPA initiative, Fast Network Interface Cards, or FastNICs, aims to boost network performance by a factor of 100 through a clean-slate transformation of the network stack from the application to the system software layers running on top of steadily faster hardware. DARPA is soliciting proposals from networking vendors. .To read this article in full, please click here

Is hybrid cloud certification right for you?

After years of shifting applications to the public cloud, enterprises realize it’s not the right fit for every app and are pulling some of them back to private clouds, forcing the businesses to adopt a hybrid strategy. But it’s not an easy process and one that may require formal training and certifications for the  IT pros tasked with this important transition.“A huge desire to move to the cloud, and pressure from lines of business to move to the cloud, have created an experience gap that has led to serious missteps and forced IT teams to repatriate workloads they had put in the cloud back into the data center,” says Scott Sinclair, senior analyst at IT research firm ESG. “IT’s level of competence, experience, and education in how to integrate with the cloud is woefully inadequate.”To read this article in full, please click here

DC 15. Segment-routing/MPLS on the data centre white box switch and VNF/PNF networking (Nokia, Cisco and Mellanox/Cumulus).

Hello my friend,

the article today would be very special because of three following points. First of all, we’ll talk about the segment routing, which is the leading technology today for building service providers and emerging for DC. Second, you will learn how to connect VNFs with the real network devices. Third, we will fork Cumulus Linux with modified FRR. Thrilled? Let’s go!

Thanks

Special thanks for Avi Alkobi from Mellanox and Pete Crocker and Attilla de Groot from Cumulus for providing me the Mellanox switch and Cumulus license for the tests. Additional thank to Anton Degtyarev from Cumulus for consulting me on FRR details.

Disclaimer

This blogpost is the continuation of the previous, where we have brought the Mellanox SN 2010 to the operational with Cumulus Linux 3.7.9 on board. If you want to learn the details about this process, you are welcomed to read that article.
