Look to Google to solve looming data-center speed challenges

Look to Google to solve looming data-center speed challenges

Google’s Aquila project is establishing a model for high-performance meshing that can handle the most demanding data-center workloads.

Suprise! The internet of things doesn’t necessarily include the internet

Suprise! The internet of things doesn’t necessarily include the internet

Connected devices need a safe, reliable network of things (NoT) that ties them together, but that glue is likely IoT-specific protocols, not the internet.

Private 5G: 4 things that determine if you need it

Private 5G: 4 things that determine if you need it

Private 5G is a major step, so consider what devices need it, whether they move around and require privacy, and whether Wi-Fi you already have meets the need.

MPLS, SDN, even SD-WAN can give you the network observability you need

MPLS, SDN, even SD-WAN can give you the network observability you need

The ‘best’ traffic paths chosen by routers in a network won’t necessarily be the fastest ones.

Basing network security on IP addressing: Would it be worth it?

Basing network security on IP addressing: Would it be worth it?

Rather than layering security onto networks, the networks and carefully managed authorization policies can hinder attacks, but at an administrative cost.

How to build a high-speed network for the metaverse of things

How to build a high-speed network for the metaverse of things

Today’s technology could build a low-latency, meshed optical network supporting real-time metaverse applications.

Surprise! The metaverse could be great news for the enterprise edge

Surprise! The metaverse could be great news for the enterprise edge

High-bandwidth, low-latency services needed to support the metaverse could also mean a better, cheaper way to provide access for edge applications like IoT.

Virtual networks need a rethink to meet hybrid-, multi-cloud demands

Virtual networks need a rethink to meet hybrid-, multi-cloud demands

Switch virtual-network providers if yours lacks a good plan to support ever more dynamic workloads.

5 best practices for making smart-building LANs more secure

5 best practices for making smart-building LANs more secure

Smart-building controllers can reduce risk of smart devices being used as entry points to the LAN, but they should be chosen and managed carefully.

How and why to adopt SDN despite its dark side

How and why to adopt SDN despite its dark side

Software-defined networking gives tighter control over network topology and management, and those not using it might find SDN is already supported in their networking gear.

Zero Trust is hard but worth it

Zero Trust is hard but worth it

Work-at-home has revealed inadequacies in perimeter firewalls and VPNs that Zero Trust can remedy if you’re willing to put in the time.

Don’t let bad press about Open RAN sink your private 5G plans

Don’t let bad press about Open RAN sink your private 5G plans

Use RFIs and RFPs to get good information about private 5G gear and to avoid being duped by stories possibly generated by 'unnamed vendors' looking to lock you into their products.

APIs pose the latest threat of networking-vendor lock-in

APIs pose the latest threat of networking-vendor lock-in

As software-defined networking becomes more dominant, the APIs offered up by one networking vendor can more severely limit interoperability with products made by others.

Juniper's marketing lags its technology

Juniper's marketing lags its technology

Juniper Networks recently made a crisp, aggressive technology presentation to analysts, but for enterprises looking to buy, it’s tough to find an equally clear story on its website.

Wacky as Facebook’s metaverse sounds, enterprises will have to deal with it

Wacky as Facebook’s metaverse sounds, enterprises will have to deal with it

Like it or not, as workers come to expect metaverse communications, enterprises networks will have to support it, so IT pros need to start planning now to fight its biggest enemy: latency.

4 questions that get the answers you need from IT vendors

4 questions that get the answers you need from IT vendors

It’s hard to set priorities for buying IT technology when vendors poorly explain what they do, how they do it, and what the concrete benefits are. Asking them these four questions can break the information logjam.

The search for the optimum network: Don’t let IT vendors sell you on lock-in

The search for the optimum network: Don’t let IT vendors sell you on lock-in

In enterprise networks, best-of-breed may be a good choice, but what does ‘best’ mean?

Tailoring SD-WAN to fit your needs

Tailoring SD-WAN to fit your needs

SD-WAN overhead, on ramps, off ramps, and security are variable and must be chosen carefully to satisfy your requirements.

Private 5G: Tips on how to implement it, from enterprises that already have

Private 5G: Tips on how to implement it, from enterprises that already have

If you’re considering private 5G for an IoT project, you’ll need to learn a lot, choose between white-box switches and servers, and maybe decide that Wi-Fi 6 is a better idea.
