BrandPost: An Efficient Network: The Fabric of a Complex Paperless Hospital System

As CTO of a large regional hospital system, I know that the network is vital to everything. I consider the network in the same critical category as electricity, oxygen, and water. It needs to be available 24x7x365 to support Concord Hospital’s half a million patients and over 5,000 network users across our 30 locations.Because we don’t do anything on paper, the network can never go down. Extreme Fabric Connect has solved that problem for us. It provides a secure, self-healing, highly-available network to serve our patients effectively in our complex paperless environment. All the Benefits of MPLS, None of the HeadachesWe decided to upgrade our network from Split Multi-Link Trunking to Fabric Connect to get the self-networking benefits of Multiprotocol Label Switching (MPLS) without the complexity. Fabric Connect is like having a carrier-class MPLS network, where you can put any network anywhere and only the right people can see it.To read this article in full, please click here

Is Patching And Tech Support Bad? A Response

Hopefully, you’ve had a chance to watch this 7 minute video from Greg Ferro about why better patching systems can lead to insecure software. If you haven’t, you should:

Greg is right that moral hazard is introduced because, by definition, the party providing the software is “insured” against the risks of the party using the software. But, I also have a couple of issues with some of the things he said about tech support.

Are You Ready For The Enterprise

I’ve been working with some Ubiquiti access points recently. So far, I really enjoy them and I’m interested to see where their product is going. After doing some research, the most common issue with them seems to be their tech support offerings. A couple of Reddit users even posted in a thread that the lack of true enterprise tech support is the key that is keeping Ubiquiti from reaching real enterprise status.

Think about all the products that you’ve used over the last couple of years that offered some other kind of support aside from phone or rapid response. Maybe it was a chat window on the site. Maybe it was an asynchronous email system. Hell, if you’ve ever installed Continue reading

Short Take – Complexity Wormhole

Have you ever found yourself in a complexity wormhole? Do you even know what that means? Russ White takes a look at some obvious symptoms that you’ve gone too far with complexity and proposes some ways to avoid the problem all together.

IDG Contributor Network: Stay smart as you approach the edge

Fundamental to harnessing the full potential of the Internet of Things (IoT) is the need for decisions to be made in real time, and it’s in addressing this that discussions have turned to the subject of edge computing over recent years.Before the data generated by myriad of connected IoT devices is sent to the centralized cloud, edge computing sees it stored and processed locally, in distributed micro-clouds at the edge of the network, closer to where the devices are placed, and the data produced. Doing so cuts down on the need for data traffic to be back-hauled to and from a remote data center, thus making it ideal for supporting the real time data delivery required by the IoT.To read this article in full, please click here

Presentation and Video: Real-Life Automation Wins

The networking engineers attending the Building Network Automation Solutions online course created numerous amazing automation solutions, most of them already deployed in production networks.

I described some of them in my Troopers 2018 Real-Life Automation Wins talk. The presentation is online and the video has been published on YouTube a few days ago. I hope you’ll find it as inspirational as the Troopers attendees did.

Did you create an awesome automation solution? I’d like to hear about it!

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

IETF 101, Day 5: All Sorted, Innit?

This week is IETF 101 in London, and we’ve been bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. Friday is only a half-day, but there’s still a couple of interesting sessions to wrap-up the week.

---

NOTE: If you are unable to attend IETF 101 in person, there are multiple ways to participate remotely.

---

Homenet starts at 09.30 GMT/UTC, and has the Homenet profile of the Babel routing protocol currently in IETF Last Call. Other drafts being discussed include the Simple Homenet Naming and Service Discovery Architecture, Outsourcing Home Network Authoritative Naming Service, and DHCPv6 Options for Homenet Naming Architecture.

The remainder of the agenda will be a discussion about Homenet security in relation to the home perimeter, HNCP and Babel, as well as appropriate trust models and how to establish trust.

ROLL continues from where it left off on Thursday morning, also starting at 09.30 GMT/UTC. There are several drafts being discussed dealing with the issues of routing over resource constrained networks where limited updates are possible.

So that brings the IETF in London to a close, and hopefully we’ve also given you a bit of an Continue reading

IETF 101, Día 5: Todo claro, verdad?

Esta semana tiene lugar el IETF 101 en Londres. El Equipo de Tecnología de Internet de ISOC te trae entradas diarias de blog que destacan los temas de interés.

A NOTAR: Si no puedes asistir al IETF 101 personalmente, hay muchas posibilidades de participar a distancia

---

Homenet comienza a 09.30 GMT/UTC. Homenet en este momento tiene el perfil  Babel del protocolo de enrutamiento. Otros borradores incluidos son: Simple Homenet Naming and Service Discovery Architecture, Outsourcing Home Network Authoritative Naming Service, y DHCPv6 Options for Homenet Naming Architecture.

Cisco, Verizon take Information-Centric Networking for a real-world spin

Cisco and Verizon teamed up recently to show off the content-aware technology they say will seriously improve the performance and security of networks of the future, including 5G wireless and IoT environments.Cisco has long been a proponent of the technology known as Information Centric Networking (ICN), which lets applications request data by a name that is based on its content rather than its location (IP address). [ Find out how 5G wireless could change networking as we know it and how to deal with networking IoT. | Get regularly scheduled insights by signing up for Network World newsletters. ] Cisco says that by using such technology the network can locate and retrieve data dynamically from any source – an important feature for future mobile and IoT environments.  As for improving security, Cisco says the technology secures and authenticates the data itself, rather than setting up point-to-point connections to authenticated hosts.To read this article in full, please click here

OCP Summit 2018

Network telemetry was a popular topic at the recent OCP U.S. Summit 2018 in San Jose, California, with an entire afternoon track of the two day conference devoted to the subject. Videos of the talks should soon be posted on the conference web site.

The following articles on this blog cover related topics:

• Streaming telemetry
• InBand network telemetry
• Black hole detection
• Troubleshooting connectivity problems in leaf and spine fabrics
• Monitoring leaf and spine fabric performance
• Leaf and spine traffic engineering using segment routing and SDN
• Marking large flows
• Broadcom BroadView Instrumentation
• Broadcom ASIC table utilization metrics, DevOps, and SDN
• Lasers!

In addition, there were a couple of live sFlow telemetry demonstration in the conference exhibit hall.
The first was a demonstration of leaf and spine fabric visibility using white box switches running the open source Linux Foundation OpenSwitch network operating system. OpenSwitch describes how the open source Host sFlow agent enables standard sFlow instrumentation in merchant silicon based white box switches using OpenSwitch Control Plane Services (CPS), which in turn programs the silicon using the OCP Switch Abstraction Interface (SAI).

The rack in the booth contains a two spine, five leaf network. Each of the switches in the network Continue reading

Lock-In And Enterprise IT – Video

Vendor lock-in isn't necessarily a bad thing if you know what you're getting into. But there are areas where vendors actively promote lock-in to capture unearned profits and control partners. Here's what to look out for.
