Las Vegas Networking Groups

If you’re in Las Vegas, Nevada, and are looking for the best places to enjoy your time and your quality business networking, do your research first and don’t spread yourself too thin.

There is a huge difference between the Las Vegas business referral organization and Las Vegas business networking organization. Here are a few you should get to know well.

3 Las Vegas Business Networking Groups

BNI

Both networking organizations and business referral organizations could be really valuable to make your business grow. If you are a member of BNI for a very long time in Las Vegas and if you put the effort into the business networking group, it would help your business grow in ways you can’t imagine. They both meet every week and attendance is necessary.

Trustegrity

Trustegrity gathers its members once a month and gives you relationships and increase the number of referrals among those in it. It is not strict about the whole one person per profession like BNI. In Las Vegas, there are a lot of different other business networking organizations that feature one member per profession. They usually have a structure in which they meet either twice a week or once a week. Continue reading

Can We Trust Server DSCP Marking?

A reader of my blog sent me this question:

Do you think we can trust DSCP marking on servers (whether on DC or elsewhere - Windows or Linux )?

As they say “not as far as you can throw them”.

Does that mean that the network should do application recognition and marking on the ingress network node? Absolutely not, although the switch- and router vendors adore the idea of solving all problems on their boxes.

UPDATE 4-23: How enterprise networking is changing with a work-at-home workforce

As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.  What follows is a round-up of news and traffic updates that Network World will update as needed to help keep up with the ever-changing situation.  Check back frequently!UPDATE 4.23U.S. Cellular, using authority granted by the Federal Communications Commission, started boosting its mobile broadband capacity in parts of six states to meet increased demand during the COVID-19 pandemic.To read this article in full, please click here

Hosts Roopa Prabhu and Pete Lumbis are joined by a special guest to the podcast, Russ White! The group come together virtually to discuss what we should think about when it comes to routing protocols in the datcenter. What are the tradeoffs when using traditional protocols like OSPF or BGP? What about new protocols like RIFT or a hybrid approach with things like BGP-link state? Spoiler alert: it depends.

Bufferbloat in Action due to Covid-19

Four people now live and work in my home 24×7; my wife Andi, her mother, my daughter and myself. Many of you now live in similar situations.jigsawfish2

Very occasionally, everyone will have network trouble, such as occurred to us this morning. Sometimes it is our “last mile” connection: it is easy to see these failures in our cable modem log. (Often available by looking at the address 192.168.100.1, which seems to be the default address for cable modems.). Occasionally it can be the ISP (in our case, Comcast), either due to some routing failure or DNS failure. These can be harder to diagnose.

Bufferbloat, however, is insidious. It comes and goes, and most users have been “trained” to ignore temporary bad behavior over many years. When you go to diagnose it, you usually stop the operation that is causing it. This blog has recorded our efforts to fix bufferbloat. Now that there are many more people at home at the same time trying to do more demanding applications, this problem is much more common. Other people in your home can inflict the bufferbloat problem on you without you or they understanding what is happening.

Day Two Cloud 045: Tackling Multi-Cloud Challenges With An Actual Multi-Cloud Consumer

We get the architectural nitty-gritty on a multi-cloud migration to Azure and Oracle Cloud on today's Day Two Cloud podcast. Guest Snehal Patel, Network and Cloud Architect for a large corporation, walks us through design and migration details as his company moves applications into two different public clouds.

The Management Plane of Multi-Cloud Networking – Aviatrix CoPilot

Recently, Aviatrix launched a new product called CoPilot to address the dire need of operational visibility in multi-cloud networking. This piqued my interest because the none of the Cloud Service Providers (CSPs) provide any topology tools for end-to-end visualization, monitoring and troubleshooting. So I decided to attend the launch event. Some of the biggest challenges … Continue reading The Management Plane of Multi-Cloud Networking – Aviatrix CoPilot

Next Generation Cognitive Networking

Just a decade ago, public cloud titans Amazon Web Services and Microsoft Azure Cloud, became synonymous with elastic scaling, and software provisioning through APIs. This was a phenomenon that didn’t exist within closed legacy systems.

Private clouds, by contrast, saw the relevance of enterprise customers recreating an infrastructure based on public cloud principles operating at a smaller scale. In an ideal world, both clouds would allow application developers to create and choose where to deploy applications without trade-offs. Arista pioneered technology development in this cloud networking category and today with Covid-19 restrictions driving millions of users to work-from-home, there are tremendous pressures on network access and bandwidth.
