How to buy Wi-Fi 6 access points

November 29, 2021 TH Author Network Security, Networking, Wi-fi

Wi-Fi 6 has some impressive improvements over its predecessor Wi-Fi 5 including lower latency, faster speeds, higher throughput, and increased range that can make it a better fit to serve both dense clusters of clients and clients running high-bandwidth applications.As Wi-Fi in general replaces wired networks in some enterprises and with the increased use of tablets, laptops, and mobile phones within enterprises, wireless-network responsiveness and versatility are becoming more desirable. Wi-Fi 6 (802.11 ax) can help. It can also improve the efficiency of IoT Wi-Fi networks by letting sensors lie idle more of the time so their batteries last longer.To read this article in full, please click here READ MORE HERE…

Rethinking the WAN: Zero Trust network access can play a bigger role

November 15, 2021 TH Author Network Security, Networking, SD-WAN, VPN, WAN

The WAN as initially conceived was about one simple job: the WAN was the network that “connects my sites to each other.” That is, the network connecting users in corporate sites to corporate IT resources in other corporate sites or perhaps colocation facilities. It was all inside-to-inside traffic.Over the past decade so much has changed that, just before COVID-19 work-from-home mandates took hold, only about 37% of a typical WAN’s traffic was still inside-to-inside, according to Nemertes’ “Next Generation Networks Research Study 2020-2021”. The rest touched the outside world, either originating there as with remote work against data-center systems or terminating there as with SaaS use from a company site or both as with VPNing into the network only to head back out to a SaaS app.To read this article in full, please click here READ MORE HERE…

Nvidia jumps into Zero Trust

November 12, 2021 TH Author Network Security, Security

Nvidia has announced a Zero Trust platform built around its BlueField data-processing units and Nvidia software.Zero Trust is an architecture that verifies every user and device that tries to access the network and enforces strict access control and identity management that limits authorized users to accessing only those resources they need to do their jobs.[Get regularly scheduled insights by signing up for Network World newsletters.]
“You cannot just rely on the firewall on the outside, you have to assume that any application or any user inside your data center is a bad actor,” said Manuvir Das, head of enterprise computing at Nvidia. “Zero Trust basically just refers to the fact that you can’t trust any application or user because there are bad actors.”To read this article in full, please click here READ MORE HERE…

Aruba switch can cut the need for separate, single-function appliances

October 19, 2021 TH Author HPE, Network Security, Networking

Hewlett Packard Enterprise company Aruba is taking the wraps of a new flagship data-center switch aimed at helping to better control and secure hybrid-cloud traffic in the enterprise.The Aruba CX 10000 Series switch is a top-of-rack, L2/3 data-center box with 3.2Tbps of switching capacity, 48 ports of line rate 10/25GbE and six 40/100GbE ports, the company says. But its most intriguing component is an integrated Elba programmable data processing unit (DPU) from Pensando that helps eliminate the need for separate appliances for security and load balancing, for example.The 10 most powerful companies in enterprise networking 2021
Pensando is a startup lead by a crew of ex-Cisco stars including its chairmen of the board, former Cisco CEO John Chambers. Others leaders of the company include former Cisco engineering icons Mario Mazzola, Prem Jain, Luca Cafiero and Soni Jiandani, collectively known as MPLS based on their first initials. The MPLS group has founded a number of companies that were spun back into Cisco during Chamber’s time as CEO including Andiamo Systems for SAN switching, Nuova Systems for data-center switching and Insieme Networks for software-defined networking systems.To read this article in full, please click here READ MORE HERE…
